ATARI Bitmap converter

Hi,

Here is a nice tool for demo creation. It's a bitmap converter, with several options. It can read any picture format ( use FreeImage internally ) and produce 1 to 4 bitplans image. Support chunky mode, 16 colors per line with dithering, support sprite sheet, etc. For information that tool was made to proceed with all bitmaps of the "We Were @" demo.

Code: Select all

Usage:   abc <input image name> [-options] <output file>
Options:
   -[1|2|3|4] : generate <n> bitplans file (4 by default)
   -chunky    : generate chunky data (1byte per pixel)
   -pal=<name>: generate palette file (444 STE)
   -rgb       : generate RGB bitmap ( 16bits per pixel, 444 STE)
   -mp15      : generate 1 palette of 15 colors per line
   -mp16      : generate 1 palette of 16 colors per line
   -sprw=<n>  : image contains <n> pixels width sprites
   -sprh=<n>  : image contains <n> pixels heigth sprites

..\..\BitmapConverter\abc large_pic.png -mp15 -chunky large_pic.bin -pal=large_pic.pal -pcp=large_pic_pc.png


To proceed the 3d sprite screen with 128 sprites cut:

Code: Select all

..\..\BitmapConverter\abc SprAnim.png -4 -sprw=32 -sprh=32 -sprc=128 -pal=SprAnim.pal SprAnim.bin

Hi

I think you somewhat duplicated part of what Troed / sync wrote 7 months ago and which has the "advantage" of using Java, so can run on any OS
https://github.com/troed/PNGconv

Options are not exactly the same, maybe you should merge both work in a "one tool to rule them all"

Oh I wasn't aware of that tool! Looks really similar. Mine just fit my needs in "We Were @" demo so it has sprite sheet support and "one palette per line" image converter. Obviously I didn't add any AMIGA options

Haha - great minds think alike My tool, of course, was also written for our needs when we made Closure
