Algoritm for collect UChar* from a QImage Object
I need perform some custom operations between the texture creation process in OpenGL, but the bindtexture operation in Qt encapsulate all this operations(Like WrapS ant WrapT texture coordinates).
It means i will need call the OpenGL bind and create Mipmaps myself without Qt , and to do that i will need access to the UChar data inside a QImage previously loaded.
Looking at the QImage Object, it exposes the UChar* data in a different fashion, where we have "Lines" of data instead of have a big block of data.
Anyone there have an already done alogorithm to read an entire image from a QImage object in a unsigned char* array?
I dont think Qt devs would store each line in a different memory section...
First line pointer valid too, or it should be.
Indeed. However, note that there might be padding between scanlines depending on your image size and format.
