Step 2 ) The following image Script-Fu: Round Corners, allows you to set the following options.

  • Edge radius
  • Add drop-shadow = Shadow X offset and Shadow Y offset
  • Blur radius
  • Add background
  • Work on copy
  • Click on Ok button

Information: I have added a border around Add background in red. I will talk about this option later on.

Step 3 ) We are going to create 2 types of round corners, one with shadow and the other with no shadow.

The following is the original image for this tutorial. It has no rounded corners.

Step 4 ) The following image allows you to select different colors for your background corner. Here you can set what ever background colour you desire.

Hint: Remember there are two types of image colors to set up. The foreground and the backgroud color. Make sure you have selected the correct color to change.

The following image has no background colour. It is set to transparent. Remember in Step 2 above, I added a border around  Add background in red. If you uncheck this option it will add a transparent background.

Note: When you have a transparent layer active. You first need to remove this, before you can execute the ‘Round Corners’ fi-script. Otherwise you can execute the script (grayed-out).

Next remove the layer alpha:
Right click->Layer->Transparency->Remove Alpha Layer
