The video in +.I matrix-stream +shall be 5, 4, or 3, depending on whether +.B -a +and +.B -l +are specified, times are wide and tall as the +video in stdin. +.SH NOTES +If both +.B -a +and +.B -l +are specified, the matrices shall have the +width and height 3 instead of 5. +.SH REQUIREMENTS +.B blind-affine-colour +requires enough free memory to load 5, 4, or 3, +depending on whether +.B -a +and +.B -l +are specified, full rows from +.I matrix-stream +into memory.
