This group of extensions manipulates the colors of a bitmap. They
are handy if you need to make a quick change to a bitmap and
don't need the power of a full-blown bitmap editor like
Gimp. The extensions all depend on
library. After an extension has been applied, the original bitmap,
either externally referenced or internal, will be replaced by a
modified internal bitmap.
Note that these extensions only work on a bitmap. Some of the extensions
can be duplicated by using Filters which also work on all objects
and don't permanently change the bitmap file.
An example of using the Implode extension (with input parameter of 1.0).
