[Marcel Wiesweg]

SVN commit 520824 by mwiesweg:

digikam from trunk:
Port "Superimpose" plugin to DImg

- use our own DImg blending support,
  do not rely on X11 (XRender) pixmaps for alpha blending
  - use DImg::bitBlendImage
  - supports 16 bit
  - is faster
- add an extra class to compute effect
- remove pixmap code from widget, adapt to new class

TODO:
There are now some issues with the size calculation, when you
zoom out too far the template is getting cropped

Marcel, the same way need to be done into InsertText plugin. I have used the
same technic (QPixmap) to merge text and target image. This way is wrong with
16 bits images...

Nothing is done into InsertText plugin in my computer. I have works to improve
B&W converter this week end following tips of Daniel Bauer (Pro-photograph
using digikam <http://www.daniel-bauer.com>).

You can fix InsertText plugin like you want.

Marcel, the plugin cannot be compiled. You have forget to add
superimpose.cpp/.h implementation into svn (:=)...

compiling superimposewidget.cpp (g++)
superimposewidget.cpp:46:25: error: superimpose.h: Aucun fichier ou répertoire
de ce type
superimposewidget.cpp:77: error: 'SuperImpose' was not declared in this scope
superimposewidget.cpp:77: error: expected `;' before 'superimpose'
superimposewidget.cpp:78: error: 'superimpose' was not declared in this scope
superimposewidget.cpp:93: error: 'SuperImpose' was not declared in this scope
superimposewidget.cpp:93: error: expected `;' before 'superimpose'
superimposewidget.cpp:94: error: 'superimpose' was not declared in this scope
