I’ve updated my cross-compile libraries:
SDL_image 1.0.4, SDL_net 1.0.1, SDL_ttf 1.0.1.
They were a bit out of date and used the old name conventions.
http://www.slothmud.org/~hayward/Xmingw32/
As noted in a previous letter, libpng and libz Xmingw32 distributions now
have the necessary development libs within them. (lib*.a).
Some problems I was having with these libraries that I’d love to have help
figuring out:
-
I can’t load PNG’s on Win NT 4 and Win 2K, but they work on Win95/98.
It gives an application error somewhere between libz.dll and
libpng.dll. Other image formats on this platform seem to work fine (only
tested png and bmp).
-
SDLimage-1.0.2 seemed a bit picky, it had problems with ImageMagick
modified bmp’s, but opening them in photoshop and resaving them fixed it!
I haven’t tried SDL_image-1.0.4 to see if this was solved. Anyone know if
this was the case? Only SDL_image had a problem with those particular
bitmaps, all other programs could read them fine.–

I think that what you have here is a case of compressed BMP’s.
ImageMagick is one of the few programs that can write RLE-compressed
BMP’s (nearly all are open source, I believe). Windoze paintbrush can’t
even read them. See if the Paintbrush can read the ImageMagick BMP’s.
Photoshop can read them, but always saves a BMP uncompressed. Strange
that the people at M$ included a system for compressing their BMP’s but
never wrote a program that implemented it!–

The windows paintbrush was able to read them.–

For anyone using ImageMagick to convert images to BMP, you can control
whether it RLE compresses the images by specifying “-compression none” from
the command line utilities. The default is to use RLE compression.> -----Original Message-----
