-
- To load a picture, select the file from the GEM ITEM SELECTOR by
- double-clicking on its filename. To change the directory path, type in the new
- pathname on the top line of the ITEM SELECTOR and click inside the directory
- window. To get the directory of a different disk, change disks and click on
- the directory bar just above the directory window.
-
- PicSwitch is fully error-trapped (I think!) using alert boxes. You are given
- the option on common errors to [Retry] the error or [Cancel]. Selecting
- [Cancel] will send you back to the file selector.
-
- The program determines the picture's format solely from the filename extender.
- Be sure to use the correct extender as listed above. IFF pics are the only
- ones that are checked for proper format. DEGAS pics (.PI1 - .PI3) are checked
- to be sure the actual picture resolution matches the extender. If it does not,
- you are given the option of viewing it anyway, or aborting.
-
- With any picture displayed on the screen, you can view the command list by
- pressing HELP, exit to the file selector by pressing UNDO (or the right mouse
- button), or [S]ave the picture in a new format.
-
- The following commands are also available for IFF pics...
- * [1]-[5] or [SPACE]:
- 'Pulls out' the selected bit-plane from the screen image. (Amiga
- lo-rez 320x200 32-color IFF pics are the only format supported in
- this version of PicSwitch. Since the ST can only display 16
- colors (4-bit planes) at a time, one plane must be taken out of
- the screen image.) Most pics look best with the default setting
- (planes 2-5 displayed).
- * [R],[G],[B]:
- Red, Green, Blue touch-up. Boosts the selected color up a notch.
- * [Return]:
- Restores the default settings.
-
- For MacPaint documents, the screen can be scrolled over the picture using the
- mouse. Pressing [S] will allow you to save the displayed portion of the
- document in DEGAS med-rez format. (MacPaint documents are 576x720 pixels.)
-
- [NOTE: If the file was downloaded with a modem on a non-Mac computer, there may
- be an extra 128-byte "MacBinary" header at the beginning of the file. If this
- is the case, PicSwitch automatically adjusts for the longer header.]
-
- PicSwitch also allows you to view DEGAS (and NeoChrome) hi-rez monochrome
- pictures normally only viewable on the Atari SM124 monochrome monitor, and you
- can permanently convert these to med-rez if you wish.
-
- Finally (for now anyway) you can view and convert screens saved with the Atari
- "Snapshot" program (found in the AtariDevelopers' sig) from medium or hi-rez
- NeoChrome to med-rez DEGAS so that you can touch them up with Tom Hudson's
- DEGAS package.
-
- If you don't have access to Mac or Amiga pics, plenty of great artwork can be
- found on the sigs here on CIS and also in the DELPHI "MicroManiac" computer art
- sig. If you find any good pics you'd like to share, upload them here! If
- possible, please retain the original artists name on the converted picture.
-
- This version of PicSwitch is in the public domain. Distribute it freely.
-
- Any comments, suggestions for enhancement, or problems should be sent to me
- here or via EasyPlex. Enjoy!
