This disk contains the CanonStudio V2.16 UPDATE. Version numbers
shown by the programs on this disk may differ and are only updated
in case the program itself was changed.
IMPORTANT: The installation requires your CanonStudio disk 1.
Note: This Update will basicly install a new copy of CanonStudio
over your old copy. Unlike older updates, it will not simply
replaced already installed files. This makes the update especialy
usefull for those switching to a different and new Canon printer
as they get a nearly complete new package.
This file contain notes about changes made after printing the
manual. We also feel that it is your right to have the
information about changes made to previous versions:
------------------------------------------------------------------
General
If your output is to dark after installing CanonStudio, make sure
you have the correct profile selected in the "Match..." window and
the Color Management System (CMS) is turned on. The default
settup after installation is usualy for plain xerox paper
(NeuSiedler's ColorCopy). Also make sure the output module is
configured as described in the profile comment (watch the print
mode setting!). Again, everything is setup after installation for
you for normal paper.
If everything is correct and the output is still too dark, adjust
the gamma slider in the Monitor (NOT "Color...") window. See the
manual for an explanation of this gamma slider and what it does.
If your output is too dark even after adjusting the gamma slider
as described by the manual, LOWER the gamma until the output does
match your requirements. Once done, all profiles you will select
later for your printer will give you good ouput.
------------------------------------------------------------------
CanonStudio V2.16 now comes with many new profiles. These new
profiles are based on Canon's latest MS Windows 95 driver V3.93.
Using these profiles with CanonStudio will give you identical
colors in the output as with a PC using the Win 95 driver.
How good are Win 95 drivers adjusted? It requires much work to
get the colors in the output of the printer adjusted correctly.
So far, there is no way to generate perfect profiles automaticly.
CanonStudio does ship with CMSScan wich is used to make profiles
on the Amiga. Sometimes the results achived using profiles based
on CMSScan are better, sometimes worse.
You'll find that the profiles based on the Win 95 driver will give
very good output quality especialy when based on new printer
drivers and when using usual print media. It's easy to understand
that adjustment efforts are more focused on the usualy used print
media like plain paper or Canon's High Resolution Paper HR 101.
Older printers are usualy not adjusted with the quality achived by
newer calibration software. That's why you'll most likely find
some Win 95 profiles for older printers to be worse compared to
the profiles generated by CMSScan on the Amiga.
But basicly things are rather simple: if you do not like the
colors in the output, make sure you did use the correct
settings/media/print head as mentioned in the profile. If you are
sure the setup of CanonStudio was done correctly, try a different
profiles. There are usualy several profiles for various settings
and print media to choose from.
IMPORTANT: Note that the Win 95 driver can't be adjusted for the
monitor gamma like CanonStudio. Because of this, set the Monitor
gamma to 2.1 if you want identical colors in the output compared
to the Win 95 driver. This note should help users working in a
mulitplattform environment.
All CanonStudio profiles based on the Canon Win 95 driver are made
for the Floyd Steinberg Serpentine dither method. This dither
method is very similar to the one used by the Win 95 driver. Use
the Avail gadget in the Match...-window for a list of installed
profiles and their used dither method and print resolution.
------------------------------------------------------------------
CanonStudio V2.13b now supports the new Canon printer series with
Photo Ink Cartridges. The Photo Ink Cartridge (ie. BC 06, BC 22
and BC22e) can be used by setting the Density gadget to
"PhotoGraph Mode" in the main CanonStudio window. You than have
to choose a proper Photo Ink color profile in the "Match..."
window in order to perform a color correction for Photo Ink mode.
Don't forget to set the print mode of the output module using the
"Config Module" menu item as described by the profile comment in
the Match window.
That's basicly it. However, some comments to clear things up:
- You can only make real use of the Photo Ink Cartridge's ability
to print 64 colors per dot by using a CanonStudio output module
for your printer. Using the Workbench module (ie. the Workbench
driver set to Photo Ink) for printing Photo Ink will lead to only
8 colors, wich are usualy printed by the normal print head with
higher quality. So don't use the Workbench module for Photo Ink
printing - use the provided output modules for your printer.
- For best quality, use at least the Canon HR 101 High Resolution
paper. It might not be the best paper, but it definitly is one of
the best I have seen and it's cheap too. Don't forget to select
the print mode in the output configuration when switching print
media.
- You need at least CanonStudio Version 2.13b for Photo Ink
printing.
- Note that the BJC 4300 and BJC 4650 do support the new BC22e
Photo Ink cartridge. This cartidge does offer Drop Modulation
Technique (DMT) combined with photo ink. Make sure that you do
not select DMT as print mode in the output configuration window
unless you do have the necessary print BC22e head.
------------------------------------------------------------------
BJC 210, 250, 240 users should use the BJC 2xx or 210 profiles
with CanonStudio. The CanonBJC 2xx printers are basicly
compatible with each other. For instance, you can use the BJC 250
profiles on the BJC 240. Only the photo ink profiles of the BJC
240 and 250 can not be used with the BJC 210 as this printer
doesn't support the BC 06 Photo Ink cartridge.
Canon BJC 2xx users can also use the b/w profiles for the BJ 10
and 200 family of printers.
------------------------------------------------------------------
Canon BJC 4000, 4100, 4200, 4300, 4550, 4650 profiles are mainly
compatible to each other as long as the recommended print mode and
print resolution in the profile is supported by the printer output
module.
For instance, you can't use the Canon BJC 4xxx profiles asking for
a Fine+DMT print mode on a BJC 4200. These print modes are only
supported on the new Canon BJC 4300 and 4650 with DMT print head
BC 21e. The DMT print mode profiles are one of the rare cases
where the new BJC 4300/4650 profiles do not work on the older BJC
4xxx printers. Because of this, the profile names do end with a
uppercase D for easy identification in the Match window of
CanonStudio. Otherwise, I can't think of a profile on a BJC 4xxx
that can't be used on any other BJC 4xxx printer.
So, check the print mode and recommended print head in the profile
comment before using it. Make sure you do have the required
settings and print head installed. This should result in very
good output.
------------------------------------------------------------------
The new Canon BJC 4300 and 4650 can print 720*360dpi. Still,
CanonStudio is installed for 360*360dpi for these printers similar
to the MS Windows 95 driver. The reason for this is simple:
these new printers offer a feature called Drop Modulation
Technique (DMT). Using DMT CanonStudio can control the drop size
of the print head. Results achived using DMT and 360dpi are
usualy much better than using the higher 720*360dpi resolution.
This is why the default recommendation for BJC 4300 and 4650 users
is: use 360*360dpi with DMT when possible. IMPORTANT: Make sure
you do have the proper DMT print head BC 21e (regular ink) or
BC22e (photo ink) when enabling DMT in the output configuration
window.
But if you don't like the recommendation, you can always switch to
720*360dpi and use other profiles.
------------------------------------------------------------------
Introducing with CanonStudio V2.16 you can find a "Fit Image on
Page" menu item. You can use this menu item to automaticly fit
the wanted picture on a page. The picture size is maximized and
centered on the page with correct aspect ratio.
The corresponding ARexx command is: MAXFITIMAGE. If there was an
error, RC is set to non-zero and PRTSTUDIO_RESULT returns the
error text. Note that the VERSION command now returns 4 from
CanonStudio.
------------------------------------------------------------------
CanonStudio V2.14c now supports the TIFF image format.
CanonStudio tries to support all requirements defined by the TIFF
V6 specifications. However, it supports far more than those
minimum requirements. It's extremly unlikely you'll find any
Amiga program that supports TIFF as much as CanonStudio does.
CanonStudio does support TIFF images with RGB, CMYK and YCbCr
color space and alpha channel. It supports images saved in strips
or tiles. It supports various precissions. The decompressions
codecs supported are None, RLE, PackBits, LZW, G3, G4, JPEG and
more. Please note that the JPEG decompression support is
according to the Tech Note #2 tag 7 scheme. The older JPEG
compression described in the TIFF V6 specification is not working
reliable.
As usual, CanonStudio does print TIFF images with nearly no
requirement for memory. Because of the way TIFF images can be
stored, CanonStudio might need a bit more memory than with other
supported image formats. There is no easy way to calculate the
memory required by the program to print an TIFF image. You can
increase the print speed for certain type TIFF images if you do
allow CanonStudio to make use of more memory if available. The
allowed memory usage is controlled by the Memory menu items of
CanonStudio. In case you don't have enough memory to print an
image, try saving the TIFF images with/without a compression
method. For instance, a 40MByte image file generate by a drum
scanner may require only 100KByte of memory to get loaded by
CanonStudio. A much smaller 1MByte TIFF LZW compressed image
might need 512 KByte more memory. Anyway, you'll find that
CanonStudio doesn't need much memory for printing TIFF images. So
enjoy.
Parts of the TIFF routines are based on the work of Sam Leffler
and others. Many enhancements/bug fixes/cleanups have been done
by Wolf Faust in order to make the library work the way it does.
It took months to create this TIFF support.

------------------------------------------------------------------
CanonStudio V2.14 now supports the BMP (sometimes called Windows
DIB) image format. Supported BMP formats are Windows BMP version
3 and OS 2 V1.x, V2.x and others: 1, 4, 8, 16 and 24 Bit.
Uncompressed, RLE 4, RLE 8 and RLE 24 compression without delta is
supported. Multiple image (or array) BMP's are supported and the
first image from the array is used. As usual, BMP images are
printed from disk without need for much memory.
------------------------------------------------------------------
CanonStudio now supports the PNG image format (PNG is pronounced
"ping"). The PNG format is intended to provide a portable,
legally unencumbered, well-compressed, well-specified standard for
lossless bitmapped image files. We hope PNG will soon replace the
well known GIF format. Beside offering more features than GIF,
PNG also offers a very good lossless compression. We are sure PNG
will soon become a well known standard beside JPEG/JFIF format
used for lossy compression
------------------------------------------------------------------
CanonStudio now supports the PCX image format. This format is
very popular on MS DOS PC's. CanonStudio supports 1,2,4,8 and 24
bit PCX files. CanonStudio is also able to print the first image
of DCX images. DCX images are mainly generated by fax software.
------------------------------------------------------------------
CanonStudio V2.11 now offers you to limit the amount of ink/color
printed using the former Separation window. The window can be
selected with the "Color..." windows using the "Color:
Separation, Weights, Usage" gadget.
Note: you can only limit the amount of ink with disabled CMS.
Otherwise it's the CMS profiles task to limit the amount of ink.
When should you use this function? Usualy whenever your output
without CMS becomes to muddy/dark because of too much ink being
printed. For instance, let's assume you want to print without CMS
on a Canon BJC 610 printer at 720dpi. In this
case, limit the amount of ink to 50% per print color. 50% is the
smallest amount giving you full ink coverage on this printer. In
most cases, you only have to use the gamma slider in the
"Color..." window in order to get good results without CMS. As
described in the Studio manual, there are special cases where
printing without CMS might be wanted.
Users wanting to create profiles should first find out the correct
ink usage for the printers before printing the color calibration
images. Enter the limits into CMSScan afterwoods. The ink limit
for your printer can usualy easily be seen when printing the b/w
greyscale calibration picture with 100% ink usage.
------------------------------------------------------------------
V2.10b offers a new Canon BJC 610 output module with 720dpi
support. Several profiles are included for printing 720 dpi.
CanonBJC610 users should always install the CanonBJC 600 AND 610
profiles. Use the CanonBJC600 profiles for printing 360*360dpi on
the Canon BJC 610.
------------------------------------------------------------------
Canon BJC70 and BC 80 users can also use the BJC 4xxx profiles
with minor color differences.
------------------------------------------------------------------
CanonStudio (V2.10) now offers a saturation slider in the
"Color..." window. An additional separation window allows you to
control the separation used by CanonStudio when printing color
images without(!) CMS.
------------------------------------------------------------------
The new separation functions offered are used for converting RGB
screen colors to CMYK printer colors. Please note that the
separation settings are used only if you print a color image
without using the CMS. CMS profiles provide their own separation
settings as the profiles are made for a specific separation
process. Changing the separation process would result in faulty
colors in the output. However, you can change the separation
function used by the CMS by changing the profile settings using
CMSEdit.
CanonStudio currently offers five different separation functions:
Internal UCR/GCR: Uses the default internal separation. The
method is simple: CanonStudio will print a black dot if a cyan,
magenta and yellow dot would otherwise be printed at the same
place.
Custom UCR/GCR: Uses the standard linear UCR and GCR
percentage settings defined by the UCR and GCR integer gadgets.
The meaning of this setting is very similar to that used by
various DTP and image processing programs on the Amiga.
Under color removal (UCR) describes the practice of removing
quantities (here defined in percentages) of yellow, magenta and
cyan from where the black is printing -- literally removing color
from under the black.
Greyscale component replacement (GCR) removes yellow, magenta and
cyan ink from where all three inks print together, and replaces
them with black. The black plate carries most of the tone in the
reproduction, therefore neutrals (greys) are easier to print.
Again, you define the percentage of how much color should be
replaced.
Custom UCR / Weak GCR: This setting uses the standard linear
UCR setting as described above, but with a preset "weak" non
linear grey component replacement function (Weak means less black
is used). The non linear function results in composite grey being
used for bright shades and black is only used for dark shades.
This gives you fewer distrurbing black dots in lighter areas of
your output. The output will look less grainy.
Instead of offering a GCR setting, this method offers a setting
for defining the maximum percentage of black being used by the
replacement function. Usually a value between 80 and 100 percent
gives good results.
"Custom UCR / Medium GCR": This setting is similar to Custom UCR
/ Weak GCR. However, the GCR function will use black for brighter
shades.
"Custom UCR /Strong GCR": This setting is similar to Custom UCR /
Medium GCR. However, the GCR function will use black for bright
shades and the increase of black is nearly linear to the amount of
composite grey of the processed color.
So, when do you need the separation functions?
Mainly when not using the CMS or when generating a profile using
the tools (CMSScan) described later in an extra chapter. There is
no general rule for which type of separation is best. The
"Internal UCR/GCR" function is very fast and offers decent
quality. The "Custom UCR/GCR" function is mainly offered for
compatibility with other programs. The last three non-linear
separation functions offer good quality. If your printer offers
good ink coverage without bleeding and similar problems, Custom
UCR / Weak GCR gives best results. For instance, if you own a
normal inkjet printer, Custom UCR / Weak GCR often gives the best
results when using coated paper. Plain paper often results in
rather worse output as too much color ink is being printed. In
those cases Custom UCR / Strong GCR might be better. Simply give
it a try and see what you think is best for your printer, paper
and dither method.
Again note: when generating a CMS profile make sure you select
the correct separation function for your set-up. Otherwise all
printed calibration pages might be useless because they would have
been made with a bad separation function.
------------------------------------------------------------------
Following additions have been made to the ARexx interface of
CanonStudio V2.10:
VERSION
Returns the version of the CanonStudio ARexx interface. Up to
version 2.09 CanonStudio returns 1 in PRTSTUDIO_RESULT. Version
2.10 and higher returns 2. Version 4 is returned by CanonStudio
V2.16 and higher.
COLOR
GREYSCALE
Selects the default output print mode. The previous setting is
returned in PRTSTUDIO_RESULT. No error is reported. Note that it
is valid to select COLOR even if the image selected is a greyscale
one or the printer driver selected doesn't support color. The
setting mainly reflects the default preset. CanonStudio will
automatically switch to greyscale printing if required.
The commands require CanonStudio V2.10 or higher. Use the Version
command for detecting the Studio version.
SEPARATION
SEPARATION 0-4
Sets the type of separation used when printing a color image
without using the CMS. The previous setting is returned in
PRTSTUDIO_RESULT. If there was an error, RC is set to 10 and
PRTSTUDIO_RESULT to "Illegal value". The following values are
supported:
0: Use the default internal separation.
1: Use the standard linear UCR and/or GCR settings defined by the
UCR and GCR commands.
2: Use the standard linear UCR setting with a preset weak (Weak
means less black is used for replacing composite grey.) non linear
grey component replacement function. The GCR command can be
used for defining the maximum percentage of black ink being used
by the replacement function.
3: Use the standard linear UCR setting with a preset medium non
linear grey component replacement function. The GCR command can
be used for defining the maximum percentage of black ink being
used by the replacement function.
4: Use the standard linear UCR setting with a preset strong non
linear grey component replacement function. The GCR command can
be used for defining the maximum percentage of black ink being
used by the replacement function.
The Separation command requires CanonStudio V2.10 or higher. Use
the Version command for detecting the CanonStudio version.
UCR
UCR 0-9999
Sets or reads the amount of under color removal (UCR) in percent.
The setting is used depending on the type of Separation selected.
The previous setting is returned in PRTSTUDIO_RESULT. If there
was an error, RC is set to 10 and PRTSTUDIO_RESULT to "Illegal
value".
The UCR command requires CanonStudio V2.10 or higher. Use the
Version command for detecting the Studio version.
GCR
GCR 0-9999
Sets or reads the type of grey component replacement (GCR) used by
the Separation function. The meaning of the GCR value mainly
depends on the separation function being used. The value either
defines the percentage for black generated from a color by the GCR
function, or it defines the maximum amount of black ink to be used.
The previous setting is returned in PRTSTUDIO_RESULT. If there
was an error, RC is set to 10 and PRTSTUDIO_RESULT to "Illegal
value".
The GCR command requires CanonStudio V2.10 or higher. Use the
"Version" command for detecting the CanonStudio version.

printing IFF DEEP images with
poster/clipping/histogram enabled.
21.07.95 V2.09 I - PNG file format support added
I - PCX file format support added
I - DCX file format support added
E - Problems with compressed Targa files fixed
27.11.95 V2.10 I - Switched to SAS/C V6.56 compiler. Optimizer now
seems to work fine and thus was fully enabled.
I - This is the major improvement in V2.10:
Scaling,
Dithering,
Border handling,
Effects,
CMS,
and much more...
rewritten for complete CMYK(!!!) processing.
Slightly faster too.
I - And this is the second major step:
CMS now accepts CMYK profiles and profiles with
various precission.
I - Saturation control added to the color window.
I - Update to PNG compression library
E - BNoise b/w dither method was not reentrant
since V2.07. Now reentrant again.
I - Separation functions/settings added.
Binary CMY->CMYK and CMYK->CMY functions
added beside the standard UCR/GCR functions.
I - SEPARATION [0-4], UCR [0-9999], GCR [0-9999],
GREYSCALE, COLOR and SATURATION [-50 - 50]
Arexx commands added. Arexx Version command
will now report "2" to reflect the changes.
E - A problem reported by a user when printing from ARexx
hopefully got fixed - even though I couldn't repeat
the problem on my machine. The problem seems to cause
dark/black images being printed when not using the
the PANEL command prior to PRINT or PRINT WAIT.
I - Blue Noise non binary dither method (previously
only used by Fargo output module) now much faster.
Also fixed: BNoise 30% was printed as 50%.
I - CanonStudio Version is now supplied to the output module.
I - CanonStudio will now switch to greyscale printing
for a specified print density if output module
doesn't support color printing for a specific
resolution.
I - Added additional functions to CanonStudio server
for upcoming PageStream V3 server printer driver.
These functions offer an easy way to a
future setup window of the PageStream driver.
E - Canon BJC800 output module didn't allowed
paper width greater 8.5 inch. Because of this,
users had to use the slower Workbench driver
for printing A3. Similar problems with right
margin do exist with other Canon modules
when printing 180 dpi. Fixed.
I - A bug in the BSC/Alpha Data Multiface III
pit.device can cause a lockup of any print
program with a priority below 0. All output
modules will now open pit.device with
a changed priority of zero unless priority
was set to high by user (in this case
pit.device is always accessed with
priority 0 anyway).
E - CanonBJ-EC right margin problems when using
a different density than 360dpi fixed.
12.02.96 V2.10c I - Canon BJC 4100 output module and profiles added.
I - New and improved BJC 610 profiles added.
20.02.96 V2.10d C - Recompiled with SAS/C Peephole Optimizer
E - Fixed a CMS bug introduced with V2.10 causing
minor color faults for certain colors/profiles.
E - Fixed histogram/clipping function. Output
was far to dark for certain images.
21.04.96 V2.11 I - ALL dither routines completly rewritten in
order to suit upcoming optimize functions
and image preview.
I - Right/Left margin handling of dither
routines is optimized depending on
image contents. When effectiv,
can lead to 1000% speed increase...
I - Following functions have been translated
to fast assembler code (% faster):
- serpentine binary dither routines (30%)
- IFF ILBM read routines (50%)
- sharp/blur functions (10%)
- 3d interpolation of CMS (10%)
I - Output modules are now listed
in alphabetical order. Doubleclick
can be used for selection.
I - CMSScan ink limit settings added.
I - CMSScan now applies a filter to CMYK
profiles removing unwanted dots
in the output. This means introducing
faults to the profile for the benefit
of better output.
10.06.96 V2.12 I - PageStream 3.0i Server driver added
I - Improved server interface
E - 2 color IFF ILBM images were not loaded
correctly by new V2.11 routines. Fixed
E - print dimension rectangle in window was wrong for
VERY large (>900 inch!) posters. Fixed
15.07.96 I - ImageFX 2.x server driver added
15.08.96 I - PageStream 3.1 beta 1,2,3 Driver added
I - Canon BJC 210 support added
05.10.96 V2.13 I - PageStream 3.2 beta 6,7,8,9 driver added
I - All binary dither routines are now up to their final
speed. This increases the Studio printing program
speed further by 5-60%.
I - Recompiled for 68060 and full optimizer.
I - Now supports progressiv JPEG/JFIF files.
Note: progressiv images currently must be printed
from memory.
I - PNG read routines rewritten for new PNG library
Version 1.0 beta 3-V0.89 and ZLIB 1.04
I - Faster image file access implemented in: IFF ILBM,
IFF DEEP, PBM, PGM, Targa, Gif, PCX, PNG.
I - Fargo output module (Ver3 Rev0) now writes/reads the
temporary files much faster (10-15% speed increase).
E - Effect window gadget scaling didn't worked for some
fonts when opening the window multiple times. Fixed
E - Landscape poster printing for small image on computers
with much memory and a high memory setting might cause
the second row of pages to get inverted. Fixed
E - Studio could have crashed if an error occured while
reading the image data of a PNG file. Fixed.
E - IFF read buffer underrun could cause Error 48 while
reading IFF ILBM images. A rare bug in the original
Commodore IFF source. Fixed.
E - Following serpentine(!) dither had a bug that might
have caused a crash in Studio V2.11&2.12: Stucki,
Jarvis and Sierra3. Again, only serpentine methods
were affected. Fixed.
01.01.97 V2.14 I - recompiled using near code model.
E - memory for dither structure for preview
wasn't free'd in V2.11 and V2.12
E - Pointer array for landscape rotation was to
small in V2.12 - 4 bytes trashed
I - BMP image format support added.
Supported BMP formats are Windows BMP version 3
and OS 2 V1.x and V2.x:
1,4,8, 16 and 24 Bit.
Uncompressed, RLE 4, RLE 8 and
RLE 24 compression without delta is supported.
Multiple image (or array) BMP's are supported and
the first image from the array is used.
E - Left white margin check in multilevel BNoise
dither routine of V2.11, V2.12 and V2.13 was
not correct and caused a slowdown.
The bug affected only very slightly the
print speed - nothing else.
I - Multilevel dither routines restructered.
CanonStudio now 40KByte smaller because of this.
I - BNoise and Order multilevel dither routines
now written in assembler (20% total speed increase!).
I - Output modules now watch data send to the
printer in order to avoid timeout problems
if print data compresses to well.
E - PageStream 3.1 and 3.2 Studio driver
did not print correctly if an unprintable
margin was entered in PageStream.
Fixed in Studio driver Ver 3 Rev 1.
I - BMP support added to CMSScan V2.14 (01.01.97)
14.05.97 V2.14c I - TIFF V6 Support added
E - color CMS profile was loaded when printing using
PageStream 3.x in greyscale mode using the Studio
driver with CanonStudio set to color.
E - PrtDevice Halftone and Order were not 100%
similar to the printer device method.
E - Server dpi info was overwritten by BMP reading
routine if defined by server (so far unused by
any server)
03.09.97 V2.15 I - Binary (that is not Photo) assembler BNoise
dither routines might show vertical stripes
in light colors caused by random number
generator introduced in V2.13.
E - Fixed a minor bug that caused the V2.14c
TIFF reader to ignore DPI information.
I - Now compiled using SAS/C V6.58
E - Fixed a bug in the left/right find() function
that might cause longword access on odd address
boundary (caused crash on old 68000 and 68010).
This bug was introduced in V2.11.
E - Fixed a bug in the printing program causing
the IFF ILBM output module to display error 14
when printing a poster with a startpage greater 1.
E - Fixed a bug in the printing program introduced
in V2.14c causing the IFF ILBM output to
fail printing non dithered 8/24 Bit images.
E - Fixed a bug when printing posters with a
startpage > 1: in certain cases the last lines
of the previous page are mixed with the start
of the first (start)page printed.
I - Changes done to the multilevel dither routines
allowing independent number of shades for each
print color. Feature not used by Canon drivers.
I - Now uses AsyncIO link library V39.2
I - IFF ILBM output module now warns when trying
to print CMYK to 8/24 Bit file.
I - major speed improvements when printing
using a startpage > 2.
10.03.98 V2.16 E - A fault in the V2.14 and V2.15 CMS trilinear
interpolation routine could cause an overflow
in case the profile values differs greatly.
As the fault introduced is usualy minor,
the fault mainly becomes visible in sudden
color changes of a smoth gradient.
I - The gamma window for measuring the users monitor
gamma now works on 16/24 Bit screens.
I - All multilevel dither routines
(Floyd, Jarvis, Stucki, Burkes, Sierra)
are now implemented in assembler.
This causes a total 30% speed increases.
I - Added Canon BJC 80, 250, 4300, 4650 modules
I - Profiles for BJC 2xx and 4xxx printers
based on the Win 95 V3.93 drivers added.
E - SetAspect ARexx command did not work correctly
while Landscape mode was enabled.
I - Fit Image on Page menu item and ARexx command added.
C - ARexx Version command will now report "4" to
reflect added commands.
I - New monitor settings added.
