TMSColor: Converter from BMP to TMS9928 format

2.4 Sep/25/2024 by Oscar Toledo G. http://nanochess.org

Usage:

tmscolor [options] image.bmp image.asm [label]

Creates image for use with assembler code

-b Generates CVBasic source code.

-n Removes CVBasic stub code for displaying.

-z Output file is compressed with Pletter.

-s Process tiles in chunks of 16 pixels high (sprites).

-sb Same as above but generates BITMAP statements.

-t Generates minimum of tiles required.

-t1 Same but starting at tile 1 (0-255).

-e45d2 Replaces color 4 with 5 and d with 2 before processing.

-fx Flip image along the X-coordinate (mirror)

-fy Flip image along the Y-coordinate

-i Generates BITMAP statements instead of DATA

-i2 Generates BITMAP statements using X and .

-m Generates magic sprites for areas with more than 2 colors

-p1 Searches best color combination for photo (slow)

-p2 Searches best color combination for photo (2x2 dither) (slow)

-o result.bmp

Outputs the final image, plus highlight of errors (if any).

-d Direct copy of binary input file to output (can compress).

Useful for getting binary data in ASM or CVBasic code.

Best photo conversion is generated by this command line:

tmscolor -p2 photo.bmp photo.bin

Photos will look better if the contrast is good.

Magic sprites will work only with an image of 256x192 pixels.

Thanks to LeandroCorreia for ideas of color conversion.
