Creating a QPixmap object from raw image data

[eumel1990]

Hello Qt centre,
as the title said I want to create a QPixmap object from an array of raw pixels. I generated this array (it is an apple man^^).
Can someone help?

You can create QImage from you raw data, using QImage::setPixel(), and then use QImage to create a QPixmap.

There is also QImage constructor that accepts char * data, if you created the data yourself, then you probably know what format does it have (by format I mean the pixel store schema, see here), so you can use this constructor directly, without looping and setting each pixel individually.

Hi,
thanks for your answers.

That is what I need:

QImage ( uchar * data, int width, int height, Format format )

QImage ( uchar * data, int width, int height, Format format )

To copy to clipboard, switch view to plain text mode 

It's better than setPixel, because I don't have to call the method million times.

Thanks a lot.
