    imagecon: --input <input1.png,input2.png...> [options]
    options:
      --output <output prefix>
      --colors <max colors>
      --quantize
      --output-palette
      --output-palette-asm
      --output-bitplanes
      --output-mask
      --output-copperlist
      --use-palette <palette file>
      --verbose

The following files can be generated:

<output prefix>.bin binary interleaved bitplane data
<output prefix>-copper-list.s m68k assembler syntax copper list with no symbols
<output prefix>-palette.s m68k assembler syntax code to install the color palette (preserves all registers)
<output prefix>.pal palette file listing the palette colors as hex
<output prefix>-mask.bin binary interleaved bitplane mask

options

--input <input1.png,input2.png...>

Specify the file(s) to be processed. Multiple files are comma separated. If bitplane output is directed, the bitplane data is stacked vertically. For images that need right padding, each line is right padded with the pixel in coloumn zero of that line.

--output <output prefix>

Specify the prefix for the output file set. Extentions will be added to this. Default is the input file name minus the extension.

--colors <max colors>

Specify the maximum number of colors allowed in the palette. Acceptable values are from 2 to 32.

--quantize

Convert the image to use less colors.

--output-bitplanes

Output the binary bitplane data in interleaved format

--output-copperlist

Output the copper is as a series of m68k instructions (No labels are generated)

--output-mask

Output the binary bitplane data for use as a blitter source mask

--output-palette

Generate a palette file of the final palette used. Output will be the output file with the ".pal" extension.

--output-palette-asm

Generate m68k assembler instructions to install the palette. No symbols are generated. Registers are preserved.

--use-palette <palette file>

Specify a palette file to use that will override the image or quantized palette. Overrides the --colors and --quantize options.

--verbose

Display debugging information

example

Create a copper list and bitplane data file with an automatically generated 32 color palette.

    ./imagecon --input full_color.png --output image-data --quantize --colors 32 --output-bitplanes --output-copperlist

Create a shared palette based on two files, then use that palette to generate image and copper list data for each file.

    ./imagecon --input file1.png,file2.png --output shared --quantize --colors 32 --output-palette
    ./imagecon --input file1.png --output file1 --use-palette shared.pal --output-bitplanes --output-copperlist
    ./imagecon --input file2.png --output file2 --use-palette shared.pal --output-bitplanes --output-copperlist
