This article explains how to save PNG image with different size formats at once in GIMP (version 2.6.3, Windows).
For saving PNG image with different size formats you need:
- GIMP - GIMP is the GNU Image Manipulation Program
- script-fu-save-icons.scm - Script for saving PNG image with different size formats.
Using this script is useful if you are creating e.g. icons and you want to save all size formats at once. Go to Script-fu » Phoca Save Icons » PNG. In opened window select which size formats you want to save. You can set various PNG options here (Interpolation, Compression, ...). Select folder where new images should be saved and click OK. GIMP will save images with all selected size formats.
