I intend to create a huge collage (22000 x 24000 pixels = 4.6 GB file
size). Working on the image becomes impracticably slow.
Is there a way to do the whole collage in small (10% of the size /
resolution), arrange layers, masks etc. in the small version until it
fits, and then convert it to the full size version? I guess that would
mean first changing the image resolution, and then have GIMP
automatically re-import all pictures (layers) in original size. It
should keep all layer properties and just recalculate all layers with
the higher resolution using the original picture size.
If there is a way to do this? Or another way to get the same result?
