makecr [-options] in_file | stdin out_fileDESCRIPTION
makecr finds connected components of black pixels in a binary image, and creates circumscribing rectangles.The file format of in_file is binary pbm(5). The circumscribing rectangles are written on out_file, whose file format is d4file(4). Each rectangle is denoted by a 4-tuple, the position of the left-top corner, the width, and the height of the rectangle.
If the string "stdin" is passed instead of in_file, makecr reads image from standard input.
