REQUIREMENTS CGFX
- cybergraphics v3/4
- cv64/3d or piv gfx-board
REQUIREMENTS P96
- p96 with *cgxvideo emulation* (v1.38)
- piv or cv64/3d
DESCRIPTION
CyberPiPView is another picture viewer with usage of the
datatypes. This program uses the videolayer feature of a
cv64/3d/piv to display pictures in 16bit no matter which
resolution the current screen has (<=8bit, 15/16/24bit).
This means that any picture can be shown in up to 65536
colors even if the current screen just has 8 colors. The
gfx processors automatically scales the picture to fit on
the screen. When the window gets resized, the picture will
be resized, too.
USAGE
From shell
----------
FILES/M: filename(s) or AmigaDOS pattern(s) of the image(s)
which shall be shown.
REQUESTER/S: pop-up filerequester even when CyberPiPView was started
with filenames given.
PUBSCREEN/K: name of pubscreen to show the pix on (must be a cgfx one).
COLORKEY/S: Normally the video layer is the front most part of the screen,
so if you move a window in front of the layer, the window
remains in the background. When using the COLORKEY option
windows can cover the video layer (see also known problems
section).
DELAY/N/K: Turns slide show mode on, each picture is shown for DELAY
seconds.
From WB
----------
CyberPiPView can be started ...
1. As default tool
2. By multi selection (click on the program icon, then select the
files to view [hold the shift key down while doing this] and
finally do a double click to start CyberPiPView).
3. By a double-click, a requester will pop up then.
The tooltypes REQUESTER, PUBSCREEN, COLORKEY and DELAY are available
from wb, too.
The window
----------
You can resize a picture using the sizegadget. Clicking on the closegadget
terminates CyberPiPView. Pressing the lmb starts displaying the next picture
in the list (if there's one:), the pointer must be over the picture.
KNOWN PROBLEMS
- Sometimes crashes your machine :( according to F.Mariak
this could be a hardware problem of the virge S3 chip. Actually,
Frank doesn't have much documentation on it, so if someone has
a good documentation on it ...
It has been reported that the vlayer feature works stable on p96.
- Downscaling isn't supported by the ViRGE chip, you might get trash
at a certain picture size.
- stripes at the bottom / right border (hardware bug?).
- When using hi-resolutions you may see flickering stripes, to avoid
this turn-off (default) the COLORKEY option. Unfortunely deactivating
COLORKEY doesn't always help because of the high bandwidth which is
required. Using CyberPiPView on screens >=15 bit doesn't make much
sense at all, use CyberView by M.Scheler instead!
- Please note that you can't grab the contents of a video layer!
- Not a bug: Please set the MULTIMEDIAMEM tooltype to YES (cvision3d
driver)! Otherwise you'll get an "out of memory" error.
HISTORY
1.0 first public release
1.1 now checks if a cv64/3d is installed (R. Reiswig),
didn't close libs when ReadArgs() failed,
window border no longer covers parts of the pictures,
added COLORKEY option (see known problems section),
added DELAY option.
1.2 removed some enforcer hits
1.3 now works with p96 picture.dt (forgot to get a new
bitmap pointer after remapping).
1.4 now works with p96 cgxvideo emulation, filerequester
remembers last path, changed handling of window
1.5 newer releases of cgxvideo.lib work buffered for both Z2
and Z3 machines. This slows down CyberPiPView, fixed
that problem by changing the way the layer is filled up.
1.6 newer releases of p96 seem to have a different LibID string
for their cgfx emulation. That's why cyberpipview failed
to work with a piv. Fixed that by removing the check for
a specific gfx-board <reported by several users>. compiled
with gnuc. v1.5 changes made the program crash on p96.
1.7 no longer refuses to work with a piv when cgfx is installed
(latest cgfx version supports piv video overlay). now opens
a simple refresh window to reduce memory usage <Frank Mariak>.
1.7a Whoops! compiled wrong source code (old MaxonC++ one).
SPECIAL THANKS GO TO
Frank Mariak for his help and reworking the cgfx autodocs and
includes ;)
R. Reiswig for his suggestions.
Emiliano Esposito for his bug report.
Jan Britsch and Olaf Krafft for beta testing and reporting bugs.
