Convert an ILBM file to PPM

Convert from stdin
cat [file.ilbm] | ilbmtoppm > [output.ppm]
Convert only the color map, not the image
ilbmtoppm -cmaponly [file.ilbm] > [output.ppm]
Convert with verbose output
ilbmtoppm -verbose [file.ilbm] > [output.ppm]
Force interpretation as HAM format
ilbmtoppm -isham [file.ilbm] > [output.ppm]
说明
ilbmtoppm converts an IFF ILBM (Interleaved Bitmap) file to PPM (Portable Pixmap) format. ILBM was the standard image format on Amiga computers. The program handles normal ILBMs with 1-16 planes, Amiga Extra_Halfbrite (EHB), Amiga HAM with 3-16 planes, Multipalette pictures (normal or HAM), color map only images, and unofficial direct color formats. It is part of the Netpbm package of graphics manipulation tools.
