QImage.scanLine pointer memory leak

[rno]

Hi,

I have a piece of code to display images one after the other. I noticed a memory leak when I "play" 100 images or so.

Here is the code

QImage image = QImage(width, height, QImage::Format_RGB32);
    uint * scanLine;
    for (int i = 0; i < height; i++)
    {
        scanLine = (uint *) image.scanLine(i);
        for (int j = 0; j < width; j++)
        {
            pixel = 0xff - c[i * width + j];
            scanLine[j] =qRgb(pixel, pixel, pixel); //memory leak here
        }
    }
    delete [] c;

QImage image = QImage(width, height, QImage::Format_RGB32);
    uint * scanLine;
    for (int i = 0; i < height; i++)
    {
        scanLine = (uint *) image.scanLine(i);
        for (int j = 0; j < width; j++)
        {
            pixel = 0xff - c[i * width + j];
            scanLine[j] =qRgb(pixel, pixel, pixel); //memory leak here
        }
    }
    delete [] c;

To copy to clipboard, switch view to plain text mode 

The image is displayed correctly but I cannot figure out what I am doing wrong here and why there is a memory leak.
height and width are 3000. c[] is a table of char with the image values. The image is a greyscale.

Can anyone help me solving this memory leak?

Cheers,
Arnaud
