... i have already explained how the task must be done in editor.
digiKam support 16 bits color depth images. We have a QImage like
object named DImg to play with 16 bits image + metadata.
If i remember, the source code available as shared libs into this project:
...do not support 16 bits color depth (this must be re-checked). If,
yes, we cannot use it as well and code must be backported into digiKam
core as a C++ extension of DImg. Code is C ansi... it's not very
About a possible kipi-plugins, there is no plan currently. DImg object
cannot be shared with kipi-plugins. Also, it's another subject. Main
goal for this GsOC entry is to make an extension of digiKam Image
Editor Resize tool.
