lbmtool

Overview

This module is a simple DeluxePaint LBM converter tool. It can convert LBMs and BBMs to JSON (including the palette, color cycling data and raw pixel indexes), or PNGs.

Usage

Use npm to install the module as a command-line executable:

sudo npm install -g lbmtool

Then call it using lbmtool and specify a path to your source LBM file:

lbmtool MYLBMFILE.LBM

By default the converted JSON data is printed to the console. If you would rather send it to a file, add the --json flag with a destination filename:

lbmtool MYLBMFILE.LBM --json MYJSONFILE.JSON

Fancy a PNG instead? Use the --png flag and a filename:

lbmtool MYLBMFILE.LBM --png MYPNGFILE.PNG

If you are using OS X, the tool can also open the image for viewing:

lbmtool MYLBMFILE.LBM --view

You can combine any or all of the above flags.

Sample Output

Here is sample JSON output from a LBM file. Note that the palette and pixel data is chopped for brevity:

{
	"filename": "SCENE.LBM",
	"width": 640,
	"height": 480,
	"compression": "cmpByteRun1",
	"masking": "mskHasMask",
	"transparentColor": 224,
	"colors": [
		[ 255, 255, 255 ],
		[ 7, 23, 27 ],
		...
	],
	"cycles": [
		{
			"reverse": 2,
			"rate": 0,
			"low": 69,
			"high": 75
		},
		{
			"reverse": 0,
			"rate": 1842,
			"low": 169,
			"high": 180
		},
		...
	],
	"pixels": [
		0, 45, 255, 0, 0, 0, 0, ...
	]
}

The compression and masking properties are only included for informational purposes. The pixel data is completely decompressed and demasked in the JSON pixels array. The transparentColor denotes which palette index should be transparent.
