The same image, before and after applying Tile filter
(We have reduced image size intentionally)
This filter makes several copies of the original image, in a same or
reduced size, into a bigger (new) image.
Activate the filter
You can find this filter through
Filters → Map → Tile.
“Tile” filter options
Tile to new size
Input boxes and their arrow-heads allow you to enter the
dimensions for the new image. Both directions are linked by
default with a chain
You can make them independent 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 which are
multiple of original sizes if you don't want to have truncated
Create New image
It's in your interest to keep this option checked to avoid
modifying your original image.
