Re: Gdk::Pixbuf::create_from_data problem

[Aurélien KAMEL <aurelien kamel gmail com>]

It don't work when multiplying my rowstride by 3, it segfault,  
probably because the source array is width*height and not  
width*height*3.

How must be organized the data in the array that I gave as argument  
to create_from_data ?

Any other solution ?
