img2scad 0.3

img2scad is a Python utility to convert images to OpenSCAD structures.

Default syntax:

img2scad [-b|--base=N] [-l|--log] < input_file

For each pixel in the input, it will create a cube in the output. The height of the cube corresponds to the whiteness of the corresponding pixel.

If -b or --base is specified, all values will be shifted by that value. This can be positive or negative. This can be used to output zero values.

If -l or --log is specified, the logarithm of the grey values will be used for the output.

Examples:

img2scad < example.png > example.scad
 Convert example.png to example.scad.
img2scad -b 1 < example.png > example.scad
 Convert example.png to example.scad, with a "bedrock" of height 1.
img2scad -b 2 -l < example.png > example.scad
 Convert example.png to example.scad, taking the logarithm for the height and preserving the black pixels.
