If gif2spr has not been placed in a directory pointed to by Run$Path then
you will need the full pathname of the program or if you are only going to
use it with Webster you could copy gif2spr into the webster directory and
set GIFVIEWER to:
GIFVIEWER:<Webster$Dir>.gif2spr -q %0 %1
Notes
-----
Only sprites with square pixel aspect ratios are generated.
This program appears to be at least twice as fast as ChangeFSI even
though ChangeFSI has hand coded LZW decompression. This made me very
happy when I tested it.
I've tested the program on 1,2,4,6,7,8 bits per pixel all the routines
have been tested since 3bpp uses the 4bpp routines and 5,6,7bpp uses 8bpp
I've only tested the transparency on 8bpp gifs, but the masking code is
almost identical to the pixel code so should not cause any problems. I
did check that part of the code for typos. The images I have were not
suitable for creating transparency masks as they were scanned in and
did not have large areas of single colour.
1.03 The code to deal with interlaced gif's has been re-coded since version
2 and is more likely to work correctly. Previously some images had a few
lines in the wrong place making the image look quite odd.
1.04 has fixed a rare problem that occured when GIF's with multiple graphic
extensions caused the error message
'liblug: Unkown input file type'
1.05 Another Rare error this was created by me several versions ago. It only happens when an empty transparent index graphic extension occurs in the data stream and generates the message
'liblug: Unkown input file type'
The -q and -v options should be seperate and not of the form -qv but this
would not make much sense anyway. This may change in the future as more
options need to be added.
