QImage rotate for tiff images

[jessiemmichael]

I used the following code to rotate and flip. I find huge data loss in .tiff and .jpeg images of larger size.

Is there any approach in QT or any other external QT/ C++ library to over come the issue.


////////rotate/////////

QImage myImage(currentFile);
QTransform myTransform;
myTransform.rotate(90);
myImage = myImage.transformed(myTransform);
 
bool ret = myImage.save(currentFile);

QImage myImage(currentFile);
QTransform myTransform;
myTransform.rotate(90);
myImage = myImage.transformed(myTransform);

bool ret = myImage.save(currentFile);

To copy to clipboard, switch view to plain text mode 

////////////////flip////////////

QImage myImage(currentFile);
myImage = myImage.mirrored();
bool ret = myImage.save(currentFile);

QImage myImage(currentFile);
myImage = myImage.mirrored();
bool ret = myImage.save(currentFile);

To copy to clipboard, switch view to plain text mode 

thank you
