PROGRAM/DISPLAY
===============
You can determine which display driver should be used for showing
graphics with the following functions.
PMPro supplies display drivers for most of the available graphic
cards (ECS, AGA, Merlin, Picasso II, Retina, EGS and CybergraphX).
But please note that the display drivers are selectable for only
those which corresponding with the hardware that is present in the
system.
Should your graphic card include special display utilities, e.g. for
GIF, JPEG or IFF, you may use these via the function "external viewers".
Configuration:
--------------
You may select the preferred display driver and configure it via
this menu . The following settings can be made :
* select display driver
Here you select the display driver module that you want
to use. Further information on the modules are described within
chapter "display drivers".
* configure display driver
Some drivers allow specific settings which are made here. They
are described in the chapter "display drivers".
* 24BIT display
Here you can specify which colour depth should be used for displaying
24BIT graphics (24BIT, Greyscales, HAM, 256 Colours etc.).
Should you own a graphic card module 24BIT should be kept.
When using AGA- older ECS drivers you can specify the preferred
colour depth for displaying 24BIT graphics. But it has to be mentioned
that displaying in 256/16 Colours takes some amount of CPU time
as a high quality colour reduction will be applied.
So don't use this function when you just want to take a quick look
at your graphic or want to do a kind of dia-show (HAM or greyscales
would be better here).
Note: This function only concerns the function Display (Pop-Up-Menu)
and Dia-Show but not the function Display within image processing
menu.
* 8BIT display
Just like with 24BIT displays you may specify here which colour depth
should be used for graphics with 256 colours. This function, though,
is mainly for Amiga's which neither include a graphic card nor
the AGA chipset (ECS-driver) to allow displaying of 256 colour
graphics. Should your machine contain the AGA chipset or a graphic
card you should always select Keep to prevent unnecessary loss in
image quality.
Your settings will be stored via the Save function and will also
be present after starting the program next time.
These settings will also be used by the program MultiConvert and
may also be saved and or modified from there.
Information:
------------
An information requester will be opened with current settings
about the selected display driver. Please note that AGA and
ECS drivers will also show up 24BITOPERATOR=ExtractGrayScales.
This does not concern displaying graphics (PopUp-Menu and Dia-show)
but instead only applies to the image processing menu.
24BIT graphics (if no graphics card driver is selected) will
always be displayed there in greyscales.
See also chapter "image processing".
NOTE: The select menu for display drivers only indicates such
===== drivers for which the necessary hardware has been installed.
For example, a Picasso-Driver will not appear if
no Picasso has been installed in the system.
External Viewers:
-----------------
This function allows binding of viewers which take over displaying
of graphics (not with Slide-show). So you have a simple method
of displaying graphics in 24BIT on your graphics card
This is useful as viewer programs
which have been especially designed for graphic cards often
work faster and more effectively than PMPro's display modules.
To use external viewers with PMPro you must copy them
(e.g. Showiff, Showgif and Showjpeg for Picasso II) to the directory
"Viewers" in the PMPro path. In addition, care has to be taken so that
the display program is able to be CLI-started with the graphic's
name as a command line parameter.
Now start PMPro and select the function "Display/external viewers".
You may now select a specific external viewer for any of the supported
graphic file formats. Please take the following steps:
1.) Select the file format (IFF, GIF, etc.) to which the new settings
should be applied within the ListView "Graphicformat".
2.) Within the ListView "Viewers" select the preferred external viewer
(or INTERNAL for the internal viewer) for this graphic file format.
3.) When selecting an external viewer the string gadget "command line"
shows up the name of the display program with the addition
"FILE$". "FILE$" is a variable which will be replaced with
the graphic's name when calling the viewer. After FILE$ there
may follow additional CLI-options for the specific viewers.
You have to confirm your selections with RETURN!
4.) This has to repeated for the other graphic file formats.
The separate functions:
- Save: Saves the current setting. These will be available
with every new run.
- Load: Loads the settings from the configuration file.
- Use: Uses the changed settings without saving these
to the configuration file(s). After leaving the
program, these will be lost.
- List: Shows the current settings of the viewers within
a window.
- Cancel: Quits the menu without keeping any of the changed
settings.
