This plug-in creates a transparent layer on top of the active layer highlighting the parts
of the image with maximum local contrast, thus the parts witch are in perfect focus.
It also show which parts of the image are unrecoverable under,- and overexposed.
Finally, if there is transparency in the layer(s), the plug-in will indicate areas
with no image information.
It is optional to sample only the active layer or all visible layers.
If the image contains a lot of detail (or noise), completion will take longer.
Enviromap V1.4 script assists in the rendering of environment maps suitable for use with GIMP's Lighting Effect plug-in. It is based on the article described here. The script uses a random seed, along with multiple user defined parameters, to generate endless variations of several types of environment maps.
EnviroLogo V1.1 allows you to quickly create logos using Environment Mapping. If you select custom Environment Map, this script will load and use it. Otherwise, it contains the same functionality as the EnviroMap script for generating Environment Maps.
