QImage loadFromData

[bunjee]

Hi trolltechers,

I'm trying to load an image and then populate another using its "binary data",
For some reason it doesn't work and image2 isn't saved.

Here is the code :

QImage image("tata.png");
 
unsigned char * bits = image.bits();
 
QImage image2;
image2.loadFromData(bits, image.numBytes() * 8);				
image2.convertToFormat(QImage::Format_ARGB32);
 
QString photoPath = "toto.png";
 
if (image2.save(photoPath) == NULL)
{
// Enters here : Image2 cannot be saved
}

QImage image("tata.png");

unsigned char * bits = image.bits();

QImage image2;
image2.loadFromData(bits, image.numBytes() * 8);				
image2.convertToFormat(QImage::Format_ARGB32);

QString photoPath = "toto.png";

if (image2.save(photoPath) == NULL)
{
// Enters here : Image2 cannot be saved
}

To copy to clipboard, switch view to plain text mode 

Any idea ?

What does loadFromData() return? It requires not only the pixel data but also the header to be present.
