From: xmerm05 AT vse DOT cz (Mertl Michal) Newsgroups: comp.os.msdos.djgpp Subject: ALLEGRO - letter to Shawn Date: Mon, 4 Aug 1997 12:58:50 Organization: University of Economics - Prague, CZ Lines: 30 Message-ID: NNTP-Posting-Host: s019h15.vse.cz To: djgpp AT delorie DOT com DJ-Gateway: from newsgroup comp.os.msdos.djgpp Precedence: bulk I mean this like a letter to Shawn, cause I don't receive any reply from him by personal mail (maybe I've got wrong address (shawn AT talula DOT demon DOT co DOT uk) or he doesn't read it - don't know). Sorry for this being off topic, but it's more than 2 months yet and I see he read the NG and my posts get inthere. I did some work on Allegro, wrote 24bit true color and rewrote load_pcx and load_tga to load any colordepth image (8/15/24) to any colordepth BITMAP. I' m, still working on some optimisations of 24bit routines. I think it'd be nice to store high/true color images on 8bit BITMAP with some optimized palette (dithering ? don't know how it's done) and with current palette. I think there could be functions like get_bitmap_specs(PACKFILE f,*width, *height,*color_depth) and bitmap loading routines would have one more parameter to tell into which colordepth BITMAP to load. I wanted to extend also LBM loading function, because there also exists 24bit LBM but I've no info about format, so Adrian Oboroc (if I remember correctly the name of the author) could be contacted either to change the routine or to send me specs for LBM format. If you didn't receive anything from me in last 3 months send me mail to XMERM05 AT vse DOT cz or post to this NG (although I'm quite sure my mail's working properly) and I could resend you my changes to Allegro. The speed of my 24bit routines is about 5 times worse than 8bit but I still think it can be optimized little bit more and I also think it needn't to be that fast as other depths, it's meant just for completness and for ability to display true color on older (mine :-)) cards. Sorry again to waste bandwidth of NG and mailing list. Michal Mertl
