Tile to new size

Width/Height

Input boxes and their arrow-heads allow you to enter you want for the new image. Both directions are linked by default with a chain; you can make them independant by breaking this chain. You can choose a unit else than pixel by clicking on the drop-down list button.

The new image must be bigger than the original one . Else, you will get an image sample only. Choose sizes that are multiple of original sizes if you don't want to have truncated tiles.
