Description Martin Kyral 2013-10-31 16:11:20 UTC
During implementation of the RAW preview support in gwenview, a need for loadEmbeddedPreview able of loading the RAW data from QBuffer (not file) arose. Temporarily, I've implemented the function within gwenview. For the sake of better maintainability of the code it would be nice to have this feature implemented directly in libkdcraw. Proposed patch is attached.

Reproducible: Always

From your patch you force libkdcraw client application to compile with libraw througn libkdcraw/kdcraw.h header :

+//LibRaw includes
+
+#include <libraw/libraw.h>

This is weird. client application don't need this dependency.
To fix it, move this method :

 private:
+    // implements loadEmbeddedPreview once the LibRaw buffer is opened
+    static bool loadEmbeddedPreview(QByteArray&, LibRaw&);
 
... to kdcraw_p.h/.cpp and remove libraw header include from shared libkdcraw header.

If you update this patch, it will be can included to git/master for next KDE 4.12. Do you have a git developer account ?

Best
