I am having a minor problem with my code.

[ayanda83]

Please see code below. I've got an 842 x595 image and I want to split it into two images of size 421x595 each, hence I used the copy function. The copying works perfect and I am able the display the first copy of my Image in the view. Please see the attached image and the output to my program.background1.jpgOutput_screen1.jpg

void Page::paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget)
{
    painter->setBrush(Qt::NoBrush);
 
    QImage image(directory);
    QImage frontPageBackground = image.copy(QRect(422,0,image.rect().width(),image.rect().height()));
    QImage backPageBackground = image.copy(QRect(0,0,image.rect().width()/2, image.rect().height()));
 
    painter->drawImage(rect, backPageBackground );
}

void Page::paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget)
{
    painter->setBrush(Qt::NoBrush);

    QImage image(directory);
    QImage frontPageBackground = image.copy(QRect(422,0,image.rect().width(),image.rect().height()));
    QImage backPageBackground = image.copy(QRect(0,0,image.rect().width()/2, image.rect().height()));

    painter->drawImage(rect, backPageBackground );
}

To copy to clipboard, switch view to plain text mode 

The problem comes when I want to display the second piece of the image and suddenly my scene looks like this.Output_screen2.jpg Please help guys. I know this is a minor problem but I just don't get why this is happening.

What is the width of your rect variable you're passing to QPainter::drawImage?

[ayanda83]

its the width of the image itself.

Have you tried copying the first image also with half width?
Line 6 of your snippet above uses rect.width() for the third argument of copy()

It doesn't look like line 6 for frontPageBackground is used at all.

its the width of the image itself.

The way I read it, you're painting only half the image. You create backPageBackground by copying half of the image's width, then you paint it in a rect that is the full size of the original image?
