Fake Engraving

 Author: Rafferty River

Create An Unique Engraving Using The Fake Engraving Plugin

This plugin fakes an engraving effect by creating several layers with layer masks
based on different threshold values of the original image. The layers are filled 
with wave patterns with various thicknesses and some of them will be rotated
for a more realistic effect. At the end the engraving layers are merged together
and a white layer is added to increase visibility.

Inspired by the Photoshop tutorial found here.

Wave patterns are created in Inkscape found here.

Instructions:
-------------
1) Copy the plugin fake_engraving.py into your Gimp plugin directory and the wave pattern files (waves0.png, etc.) into your Gimp patterns directory.
2) Start Gimp and open an image of about 1000 pixels or more at 300dpi which has sufficient contrast.
3) Apply the script in the Python-Fu menu.

  1. Rafferty -- hey thanks so much! So question. If I put the *.png files into the directory GIMP doesn't see them as brushes. They have to be opened in GIMP, then saved as *.gbr files. Then GIMP will see them, but unfortunately the script will not see png files, or gimp brushes named as either waves0 or waves0.png.
    "Calling error for procedure 'gimp-context-set-pattern':
    Pattern 'waves0.png' not found"

    Any advice?

  2. Hi,
    Don't see my comment, so am re-commenting with google account.
    I am getting an error that brush wave0.png cannot be found.

    I think I don't understand the instructions, or maybe this works only on an old version GIMP that uses png's for brushes? GIMP 2.10 requires gbr files. So copying the pngs into the user brushes directory doesn't cause them to show up as brushes within GIMP, nor to be seen by the script. I did create brushes with names wave0.png.gbr and wave0.gbr, but neither of those files worked with the script. Does the script look into a hard-coded directory, or is it hard coded for the wave0.png filename? If so what version of GIMP did you use, because I'd really really love to try this. Id be happy to send some $ if it works well.

    Thanks!
