icptoraw converts an image component (ICP-format) into a raw-format file consisting of a 2D array of integer pixels.
The option -bpp specifies the number of bits that each pixel value contains. bits_per_pixel must be between 1 and 32. If bits_per_pixel is <= 8, then each sample is stored in rawfile as the least significant bits in a single byte; otherwise, if bits_per_pixel is <= 16, then each sample is stored in rawfile as the least significant bits of two consecutive bytes (the default); otherwise, if bits_per_pixel is <= 32, then each sample is stored in rawfile as the least significant bits of four consecutive bytes. -bend and -lend indicate whether the raw file is to be written in big-endian or little-endian format, respectively. If neither is specified, big-endian is assumed.
rawfile is stored in row-major order.
