- Description
- -----------
-
- ShowGIF is, as the name says, a GIF viewer for the Picasso-II graphics board
- of VillageTronic.
- The program can be started from CLI or Workbench with one or more file
- names/icons. If the program cannot load an image (because you didn't submit
- a filename or the file doesn't exist), a file requester pops up.
-
-
- Usage
- -----
-
- From CLI: ShowGIF Image [...]
-
- Template: FILES/M,BUF/N,DELAY/N
-
- FILES/M: One or more filenames to be viewed
- If no filenames are given or the files weren't GIFs, a
- file-requester pops up.
- BUF/N: Specify the FileBufferSize in KB, like BUF 100
- DELAY/N: Specifies the delay in seconds after showing the
- picture. If none is given, the program waits for
- a key or a mousebutton.
- Remember: during this delay, the program can't be
- stopped !
-
- Examples:
-
- ShowGIF BUF=5 SYS:Images/Globe.gif
-
- ShowGIF DF0:Pictures/Mercedes.gif DF0:Pictures/Family.GIF BUF 10 DELAY 5
-
- From Workbench:
- - Default Tool: Specify ShowGIF as the default tool of an image
- - Multiple selection: With the shift-key pressed, select an image and
- double-click on ShowGIF's icon.
-
- There are no arguments from the WB.
-
-
- Features
- --------
-
- - fully programmed in assembler
- - uses a file buffer (50 KB by default)
