Drop Shadow Advanced

Gimp 2.8 required!

This plugin produces a complex three-part drop shadow from a selected layer. Ideal for light-on-light text (or anything else).

Features:
* Super-smooth shadow algorithm
* Three customizable shadow layers (umbra, penumbra and veil)
* Works with both alpha and masks, shadows are created as masks
* All layers (including the source) are put into a separate group, so no mess created

Usage recommendation: If you need a simpler type of shadow just set opacity of the unneeded part to 0 - no corresponding layer will be created. For example, if you need only umbra, set the penumbra and the veil opacity to 0.

Example:

History:
v1.03: Much faster smoothing approach; Umbra/penumbra and veil colors now are selected with the color selection dialog
v1.02: Added "Move the source layer into the group" (off by default) and "Flatten the group" (on by default)
v1.01: The filter moved to "Filter/Light and Shadow" (thanks to Rod)
v1.0: Initial release
