REQUIREMENTS (PLEASE READ THIS;)
- cybergraphics v3 (, pictdt43)
- cv64/3d gfx-board
DESCRIPTION
CyberPiPView is another picture viewer with usage of the
datatypes. This program uses the videolayer feature
of a cv64/3d (currently the Picasso IV isn't supported)
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 scaled, 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.
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 ...
- Scaling doesn't always work perfect, sometimes you get trash at
a certain size (hardware bug?).
- 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).
SPECIAL THANKS GO TO
