- Save Degas snapshots of screens from within
- other programs using this powerful utility
-
-
- SNAP.TOS is a simple, but useful snapshot utility that saves the ST's screen
- when a certain combination of keys are pressed. When it is run, it hides itself
- in memory and quickly returns to the desktop. Now you can run another program,
- and at any time, you can press the special control keys to save the screen.
-
- It works in any screen mode and saves ordinary Degas (uncompressed) screens
- - PI1 in low resolution, PI2 in medium resolution and PI3 in high resolution.
- It's useful for grabbing screens and artwork from other software for inclusion
- in your own, for instance, for pasting mono images onto DTP pages, or taking
- sprites from pictures and so on.

- How to use it
- --------------
- Boot up your ST as normal. When you want to take some snapshots double click on
- SNAP.TOS on the desktop to install it in memory. Now boot up your software as
- and whenever you want to save the current contents of the screen press
- Control+Alternate+both Shift keys.
-
- Every time you press this combination of keys the screen will be saved -
- first as SNAP_A.PI? then SNAP_B.PI? followed by SNAP_C.PI? and so on. It saves
- to the currently selected disc and directory. Switch off the ST to remove it
- from memory.

- Problems
- ---------
- The program works by intercepting the TRAP #13 vector and checking for the
- Control+Alternate+(both)Shift keys being held down. However, if a program
- doesn't call TRAP #13 for anything (unlikely, because most programs call TRAP
- #13 most of the time) then the screen won't be saved.
-
- I found one program that while booting up somehow fooled Snap into thinking
- the hot-key combination was being held down and the screen was saved a couple
- of times with nothing on it. Once the program was running the other snapshots
- were fine.
-
- Make sure you have plenty of free disc space available as each screen saved
- takes up 32k. Also, Snap doesn't check for overwriting existing files, so, for
- instance, SNAP_A.PI1 will overwrite any existing SNAP_A.PI1 file.
