Porting Scripts for GIMP 3.0

26 November 2025

GIMP 3.0 hit my Linux machines a while ago, and all my personal and 3rd-party scripts broke.

I finally took a moment to look at the errors and figure out what needed to be updated.

My simplest script merely sets the current layer’s blend mode to Soft Light, but even that broke. Why’s that useful? Once there’s an action in the menu, I can bind a keyboard shortcut (Ctrl-S) to it. I need to switch lots of new layers to Soft Light: High Pass for sharpening, or a layer for dodging and burning.

Registering the menu is what often failed:

attempted to install procedure ""
with a full menu path "<Image>/Shortcuts/_Change to Softlight" as menu label,
this is not supported any longer.

To fix it, we move the menu path into a separate call, instead of all at once in script-fu-register.

Here’s the fixed script:

(define (softlight-layer img inLayer)
  (gimp-layer-set-mode inLayer LAYER-MODE-SOFTLIGHT)
    (gimp-displays-flush))

(script-fu-register
    "softlight-layer"                         ;function name
    "Change to Softlight"                     ;menu label
    "Change current layer to Softlight mode"  ;description

    SF-IMAGE "image" 0

(script-fu-menu-register "softlight-layer" "<Image>/Shortcuts")

Watching for GIMP 2.10.1

13 May 2018

I was seeing the new GIMP 2.10.0 doing bad things with multiple gradients on a transparent layer, so I logged Bug 795866. They quickly fixed the bug within 48 hours, but now I’m sitting here reloading the GIMP news page to see if they’ve cut the newest release.

Update: GIMP 2.10.2 just hit Debian Unstable!
