Rotation along the Y-axis

Overview of program, to understand Question
I'm loading an image in type QImage
Then I paint the image in label,
& allow user to make markings on image (draw point/ellipse/...)
After the user finish editing the image
All the points the user created via mouse clicks is stored in an array.

Later in the program I'm rotating image along the y-axis then repainting the image.
but when I paint all the points that were stored in array its not being rotated accordingly(naturally)

The rotation of image along the y-axis.... Works
How do I rotate the points along the same axis so its inline with image

ie(creating a perspective look on output)

code to transform image

Code:

---

//before paint function
 QTransform pptv;
    pptv.rotate(-60, Qt::YAxis);
    image1 = image1.transformed(pptv);
    imageDrawFlag1 = true;

---

& i paint the transformed image
but when it comes to repainting the points:confused:

Code:

---

//In paint function
foreach(tempPoint, markers)
     {
        painter.drawEllipse(tempPoint, 5, 5);
     }
//painter.rotate -> only allows an integer, Does not allow which axis

---

How would I go about solving this issue?

Kind Regards

Having some network issues today, my posts or responses might be delayed

can you save all of your paintings in another image, and rotate that image?

What happens if you call QPainter::setTransform() with the same transform?

QPainter::setTransform() with the same transform... Works
