![]() (For ImageMagick 7 I believe the command is "magick" rather than "convert") $ convert myimage.jpg -extent 10523x4960 -crop +repage mytiles.jpg And suppose it's 300dpi, so the total image is 10523x4960 pixels. Suppose that's myimage.jpg, and it's going to be 3 pages across and 2 pages down to print. In the 80x40cm case, your image should be padded to 3x29.7=89.1cm width (three A4 lengths) and 2x21=42cm height (2 A4 widths.) ![]() ImageMagick does this pretty well, by easily splitting an image into equal-sized tiles.įirst make sure your image is sized properly so that, after it is split into equal sized tiles, each tile is the size of the paper you are printing to (otherwise you'll be doing a lot of trimming.)įor example, pad your image with white pixels.
