SGRAB DOCUMENTATION
|
||
|
|
-------------------
|
||
|
|
|
||
|
|
SGRAB [-s | -c] [-p] filename
|
||
|
|
-s force seperate files
|
||
|
|
-c force a composite .DAT file (default)
|
||
|
|
-p wait for a keypress after each grab command
|
||
|
|
|
||
|
|
|
||
|
|
Filename should be the root (no extension) of the picture (.LBM) to be
|
||
|
|
grabbed. The script file (.SCR) is read in and parsed, causing lumps to be
|
||
|
|
grabbed off the screen and saved into an output data (.DAT) file.
|
||
|
|
|
||
|
|
If the -s option is used, or the first command in the script file is
|
||
|
|
$SEPERATE, the lumps are each saved to a seperate file, rather than being
|
||
|
|
combined into a composite file.
|
||
|
|
|
||
|
|
|
||
|
|
The script file format is as follows:
|
||
|
|
|
||
|
|
[$SEPERATE]
|
||
|
|
lumpname grabcommand [parameters]
|
||
|
|
; Comments can be uses at the beginning of a line, or after a command's parms
|
||
|
|
; whitespace can be introduced anywhere, but a command cannot cross lines
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
If the lumps are being saved individually, lumpname can be any valid pathname,
|
||
|
|
but for composite files it must be a filename[.ext] size.
|
||
|
|
|
||
|
|
|
||
|
