Script-Fu Charcoal-Layer-FX v1.0 by Micomicon March 2011
A Gimp script which takes the effect from my Charcoal script and adds it as a layer or layers. NB. Does not require charcoal.scm to be installed.
Opening the Layers Dialog and scrolling through the layer modes afterwards can produce some interesting results akin to adding a watercolour wash, the strength of which can be varied by adjusting the opacity slider.
Thanks to mahvin for this change of direction.
To install (Linux):
Download and move the script file charcoal-layer-FX.scm to /yourhome/.gimp-2.x/scripts.
A Gimp script which turns a photograph into a black and white image which can look quite like a charcoal drawing. Works with RGB, Indexed and Greyscale images.
Results can be variable and are dictated by the tonal values of the photo used. Although small adjustments can cause quite large differences, the default settings should provide a reasonable starting point but do be prepared to experiment.
Scales an image multiple times in defined step sizes until the desired size is reached while retaining the aspect ratio of the image.
This is basically the "Scale in steps" script from K.-M. Hansche tailored to my needs.
Give the desired size of the image and select whether this is for width or height. The step size defines how much pixels the image will be shrunken every time. When flattening the image, the layers will be merged and the image is automatically cropped. The other options control the scaling itself.
