HELP - problems with SCALE and POSITION when saving an image on top of another image

//this has rotation, and scale pinch event handlers and working well
object = ImageView::create("asset:///images/itsmorefunlogo.png");

QImageReader reader;
reader.setFileName(appFolder + "app/native/assets/images/background.jpg");
QImage image = reader.read();
QPainter painter(&image);

QString bomberFileName = appFolder
			+ "app/native/assets/images/itsmorefunlogo.png";
reader.setFileName(bomberFileName);
QImage bombimage = reader.read();

QTransform imageTransform;
imageTransform.rotate(object->rotationZ());
imageTransform.scale(object->scaleX(),
			object->scaleY());

bombimage = bombimage.transformed(imageTransform);

painter.drawImage(QPoint(object->translationX(), object->translationY()), bombimage);
image.save(fileName, "JPG");

 I am not getting the correct POSITION and SCALE, only the ROTATION is perfect.

In my app I can pinch to scale and rotate the object (ImageView) and I have a button to save it and after it saves, the scale is not the same and the position.

Posting some images may help to illustrate what the actual issue is.

A shot in the dark: Have you tried reversing the rotate and scale commands (so doing scale first)? The concept of transformation matrices can be tricky if on is not used to them.

Glad I could help.

(why not like the post if it solved the issue:-)

[nemory]

my issue is not yet solved.

[nemory]

reversing the scale and rotation still does not help

I can't see the images yet, just placeholders.

Sorry, what do you mean?
