- 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).
