Description
We need to:
- Add an API in MosaicImageWriter for applying an operation on the source tiles, before to write the target tiles
- Add a convenience method defining an operation for making border transparent. This operation would be based on the "SilhouetteMask" image operation.
- Get MosaicImageWriter to cache the result of that operation in temporary file while building the mosaic.
- Add a panel in MosaicWizard for selecting the border color to make transparent, and give the selected colors to the above API.
This has been implemented in Geotk. However the current algorithm is inefficient and should be replaced by a scan line flood fill algorithm. This is a task for the coverage module rather than the wizard module.
