QImage Rotation and Translation & Invert Specific Colors

[2lights]

Good Day,

Part 1 of 2
Im superimposing 2 images(Overlaying images, with the 2nd image having a 50% opacity)

Now I have a rotation angle, a Row Offset & Column Offset Value.

When I rotate the 2nd image... it works
When a call the TRANSLATE function nothing happens!

Overlay Images Function:

primaryImage.load(imageFileName1);
 
     secondaryImage.load(imageFileName2);
     secondaryImage.invertPixels(); //Inverting Grayscale Image
 
     QTransform rotating;
     rotating.rotate(RotationAngle);
     secondaryImage = secondaryImage.transformed(rotating); // Works
     QTransform translating;
     translating.translate(RowOffset, ColOffset);
     secondaryImage = secondaryImage.transformed(translating); // Does not work
 
     paintScreen = true;
     update();

primaryImage.load(imageFileName1);

     secondaryImage.load(imageFileName2);
     secondaryImage.invertPixels(); //Inverting Grayscale Image

     QTransform rotating;
     rotating.rotate(RotationAngle);
     secondaryImage = secondaryImage.transformed(rotating); // Works
     QTransform translating;
     translating.translate(RowOffset, ColOffset);
     secondaryImage = secondaryImage.transformed(translating); // Does not work

     paintScreen = true;
     update();

To copy to clipboard, switch view to plain text mode 

this is what I got:

//Paint Function
    if(paintScreen = true){
 
    //Repaint Primary Image
    painter.drawImage(QPoint(0, 0), primaryImage);
    painter.setOpacity(0.5);// drawn at n% opacity
    painter.drawImage(QPoint(0, 0), secondaryImage); }

//Paint Function
    if(paintScreen = true){

    //Repaint Primary Image
    painter.drawImage(QPoint(0, 0), primaryImage);
    painter.setOpacity(0.5);// drawn at n% opacity
    painter.drawImage(QPoint(0, 0), secondaryImage); }

To copy to clipboard, switch view to plain text mode 

Ideas Please
Solutions welcome


Part 2 of 2
Also Instead of inverting colors of 2nd image(grayscale)
Is there a way to convert the whole image into like a "Red Scale" or any other color of different shades

Solution
Kind Regards
