Hi all,

I am developing small application which can edit image.That is it has Zoom and Erase functionality.

I am facing performance issue when i zoom the image and starts erasing it.

Zoom functionality is implemented by scaled() API of QImage and erase functionality is implemented by drawing on the scaled image with CompositionMode set to QPainter::CompositionMode_Clear.

How MSPAINT application does the same task smoothley.

Is there any way to improve the performance?

Thanks in advance
