• polar.c 2.00 (15.657 Bytes)
  
  is a filter similar to Photoshop's "Rectangular to Polar" and "Polar to Rectangular" filters but with much more parameters.
  
  Examples from left to right: source image, rectangular to polar, polar to rectangular

  
  
  
  
  

• blackwhite.c 1.00 (6.347 Bytes)
  
  sets color values below a threshold to 0 (black), color value above to 255 (white). With rgb-option enabled it operates on each rgb-part instead of the whole triplet.
  
  Examples from left to right: source image, threshold 64, 128 and 192

  
  
  Examples: same threshold but with rgb-option enabled

  
  
  
  
  

• blur-mask.c 1.00 (5.285 Bytes)
  
  is a variation of Torsten Martinsen's "Variable Blur" filter. You can specify a mask image that defines the blur depth for every pixel. Black areas won't be blurred, white areas will be blurred with maximum amount (linear interpolation).
  
  Examples from left to right: source image, mask image, blurred with 12

  
  
  
  
  

• lensflare.c 0.01 (18.070 Bytes) (developer release - ugly but it works)
  
  simulates the "sun in the camera" effect. Features in development: Editors for different flares and lenses.
  
  Examples from left to right: source image, brightness 50, 100 and 200

  
  
  
  
  

• fade.c 1.00 (6.677 Bytes)

• The GIMP - Programmer's Reference Book
  
  This document is part of the GIMP Documentation Project. It is available in various formats:
  
  
  • gimp.prb.0.03.html (HTML online documentation)
  • gimp.prb.0.03.sgml (SGML source)
  • gimp.prb.0.03.dvi (device independent file)
  • gimp.prb.0.03.ps (postscript)
  • gimp.prb.0.03.html.tgz (contains all HTML-files of the document)
  
  I hope this will be useful for you programmers out there to write much more nice plug-ins.
