Does anybody know an existing implementation of an alternate QImage:scale that returns a smoothed but sharper result? Something like "Bicubic (sharper)" in your graphic application of choice.

Calling QImage:scale with Qt::FastTransformation results in unreadably jaggy text and Qt::SmoothTransformation is very blurry.

Looking at "qimagescale.cpp", I would like to avoid writing it myself but couldn't find any hint towards an existing implementation.

Thx in advance,
