QPixmap pixel by pixel ?

[elcuco]

Thanks Elcuco,

Do you know if operating with Qimages (converting and reading them etc) is significantly faster that bitmaps?
How do you open a QImage for data input? It's not really a file that you can open like you open a binary in C/C++, is it?

Hi Tommy,

I loaded the image using QImage::load(), and then I pass it to a ansi C library for manipulation. I know that in most cases, you can treat the bits() function as something similar to this:

dword picture[SIZE_Y][SIZE_Y] ;

dword picture[SIZE_Y][SIZE_Y] ;

To copy to clipboard, switch view to plain text mode 

It will fail sometimes. Be warned (at least in MACs). If you want to review my code, here it is: http://code.google.com/p/qhocr/
