winicontoppm - convert a Windows .ico file into 1 or more portable pixmap files SYNOPSIS
winicontoppm [-writeands] [-allicons|-bestqual] [-multippm] [-verbose] [iconfile] [ppmdestfile] DESCRIPTION
Reads a Microsoft Windows .ico file, converts it to one or more ppms. A Windows icon contains 1 or more images, at different resolutions and color depths. Each image has an 'and' mask, which contains transparancy data. By default, the output goes to Standard Output. If you specify ppmdestfile, output goes into one or more files named as follows. If it's just one file (i.e. you specify the -multippm option or don't specify -allicons), the file specification is ppmdestfile.ppm. If it's mul- tiple files, their file specifications are ppmdestfile_1.ppm, ppmdestfile_2.ppm, etc. When you specify the -writeands option, the filenames above are modified to include the string xor as in ppmdestfile_xor.ppm or ppmdest- file_xor_1.ppm. winicontoppm can convert images with 1, 4, 8, 24 or 32 bits per pixel (bpp). OPTIONS
-writeands For each icon written, also write the 'and' (transparancy) mask as a seperate PBM file. It's name is of the form ppmdest- file_and.pbm or ppmdestfile_and_1.pbm. -allicons Extract all images from the .ico file. -bestqual Extract only the best quality (largest, then highest bpp) image from the .ico file. -multippm Write all ppms to a single file.

ppmtowinicon - convert 1 or more portable pixmaps into a Windows .ico file SYNOPSIS
ppmtowinicon [-andpgms] [-output output.ico] [ppmfiles...] DESCRIPTION
Reads one or more portable pixmaps as input. Produces a Microsoft Windows .ico file as output. A Windows icon contains 1 or more images, at different resolutions and color depths. Microsoft recommends including at least the following formats in each icon (size and bits-per-pixel): 16 x 16 - 4 bpp 32 x 32 - 4 bpp 48 x 48 - 8 bpp Default I/O is STDIN/STDOUT. OPTIONS
-andpgms If this option is given, every second file is read as an "and mask" to be used by windows for transparency data for the previous image. (These are set to fully opaque by default). The and mask is a PGM image, where any pixel with maxval intensity means opaque and any other pixel means not opaque. Note that as with all Netpbm programs, you may use a PBM file here and it will be used as if it were the equivalent PGM. The and mask is like an alpha mask, except for what it signifies in the "not opaque" areas. In the usual case, the foreground image is black in those areas, and in that case the areas are fully transparent -- the background shows through the icon. But in general, a not opaque pixel signifies that the background and foreground should be merged as follows: The intensities of the color components in the forgeground and background are represented as binary numbers, then corresponding bits of the background and foreground inten- sities are exlusive-or'ed together. So there is a sort of reverse video effect. -output output.ico File to write. By default, the icon is written to stdout. SEE ALSO
