Hi there,
I do comics trip as a hobby. Here are some of my works. I use gimp for text, editing, sometimes coloring or texturing. I will show in this thread the scripts I did to ease some tasks. Comments and advice are welcome
This first script is made to prepare a scanned drawing. automatize de-saturating, changing contrast and light, and separate the ink from the background, so I can add a color layer in between and paint.
This second script is made to move all the text layers in a layer group named texts.
Im presently working on a script that makes a text bubble around a text layer.
enjoy !
