In fact its major use is for either -tile or -map See also Canvas Creation, "Tiling using in-memory images" http://www.cit.gu.edu.au/~anthony/graphics/imagick6/canvas/#tile_memory Which lists MPR: with two other methods of doing the same thing. | "The image sequence following the -write filename option is written out, and | processing continues with the same image in its current state if there are | additional options. To restore the image to its original state after writing | it, use the +write filename option." | I have not played with +write as I generlly use \(..\) and -clone to make copies of images I need to keep unchanged. | It seems to me that the image sequence *preceding* the -write should be (and | is) written. | | convert ( -size 50x50 xc:#aabbcc -fill blue -draw "polygon 7,38, 32,4 32,46 | 7,12 47,25 " -write mpr:mystar ) -size 500x500 xc:#ffcccc -tile mpr:mystar - | draw "polygon 49,396 327,14 327,486 49,104 498,250" -delete 0 filled.png | NOTE, there is no need to start with parenthesis, as you start with a blabk image sequence anyway. After writing a image to a Mpr: you often +delete the image from the current image sequence, to start fresh.
