Convert an ILBM file to a PPM image

$ ilbmtoppm [path/to/file.ilbm] > [path/to/file.ppm]

$ ilbmtoppm [[-t|-transparent]] [color] [path/to/file.ilbm] > [path/to/file.ppm]

$ ilbmtoppm [[-ig|-ignore]] [chunkID] [path/to/file.ilbm] > [path/to/file.ppm]

$ ilbmtoppm [[-m|-maskfile]] [path/to/maskfile.pbm] [path/to/file.ilbm] > [path/to/file.ppm]

ilbmtoppm [ilbmfile]

[ilbmfile]
    The name of the ILBM file to convert. If no file is specified, ilbmtoppm reads from standard input.

ilbmtoppm is a command-line utility that converts Interleaved Bitmap (ILBM) image files, a format commonly associated with Amiga computers, into the Portable Pixmap (PPM) format. PPM is a simpler, widely supported image format that's easy to process with various image editing and viewing tools.

The command reads an ILBM file as input and produces a PPM file as output. This allows users to view, manipulate, or convert ILBM images on systems that don't natively support the ILBM format. It handles different ILBM features like color maps and transparency masking. The command aims for faithful conversion, preserving color information and transparency where possible.

It's a useful tool for anyone dealing with legacy Amiga image files who wants to view or further process them on modern systems. It is part of the netpbm suite of image manipulation tools.

Convert an ILBM image named "image.ilbm" to a PPM image named "image.ppm".
