A revised version of my first script I wrote in 2009 during a boring weekend, this script takes an image as input, duplicates and flattens it, and then applies several plugin and script-fu effects on a dozen different layers to create a paper or parchment-like effect on the cheap, with the final output an image with layers and some layer masks. An optimal input image is a 1000x1000 square image (maybe I'll update the script to fix that "square" part; the problem is a round blend, but it's not that hard to fix after-wards), but it scales more or less.
The "script-fu-pixelraster"-function creates a color-averaged Dot-Map with a selected Brush and a matching masked copy of the active layer.
You can select a brush and enter the amount of colums and rows your raster should have.
Works on RGB-layers only.
Update: the No-Undo Version works much faster on large rasters. Since all changes are made to new layers, you actually don´t need the other version.
So, I've been playing a bit more lately with emulating the effects produced when shooting on some 5 year old Polaroid 600 instant film. I took some shots the other day with it, and it produced these really neat areas of the film where no developer had reached, leaving this strange and interesting splotches of un-developed print behind.
I thought it might be fun to emulate in GIMP, and even better to reproduce the effects with a little script-fu (for practice).
This Script-Fu Script goes through all picture files in a directory and make 4 common operations on them;
- Scales to a ratio defined in the script startup
- Levels Use Auto Level on the picture (if the user selects this)
- Sharpen Uee 40 % sharping (if the user selects this)
- Sharpen with unsharp mask (if the user selects this)
- Creates and store away a copy of the file with an added (user defined) suffix)
