makepr(1) General Commands Manual makepr(1) NAME makepr - create Primitive Rectangles in an image SYNOPSIS makepr [-options] in_file out_file [ out_file2 ] DESCRIPTION makepr reads a binary image and creates Primitive Rectangles. The Primitive Rectangle is the rectangle whose width is a constant (column width). See references for the detail of Primitive Rectangles. The file format of in_file is binary pbm(5). The primitive rectangles are written on out_file and out_file2, whose file format are d4file(4) ordinally. 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 option -image is specified, the rectangle image is written on out_file. The file format of out_file is binary pbm(5) in this case. OPTIONS -or Logical "OR" of black pixels is used at the creation of rectan- gles. (This is default.) -and Logical "AND" of black pixels is used at the creation of rectan- gles. -reverse Reverse black and white of the input image. -cwid N Set the width of Primitive Rectangles to N. The default value is N=16. -image Create image file instead of rectangle file. -box Fill the inside of rectangle by black. Use this option with -im- age. -vert Create the vertical Primitive Rectangles instead of normal hori- zontal ones. -mvec Create both horizontal and vertical Primitive Rectangles concur- rently. Horizontal and vertical rectangles are written on out_file and out_file2 respectively. -d8 Create 8-dimensional (8-tuple) file. (This is experimental.) -llim N Suppress writing Primitive Rectangles each of whose height is less than N. The default is N=1. -ulim N Suppress writing Primitive Rectangles each of whose height is more than N. The default is N=32767.
