Using QImage with OpenGL

Question

I\'ve very recently picked up Qt and am using it with OpenGL The thing though is that when moving my SDL code to Qt and changing the texture code to use QImage it stops work

Answer 1

This is my solution for conversion from Qt to GL This also can work in reverse with little changes; Cheers -- Daimon

void Image::Convert32bitARGBtoRGBA()
{
    if(!isQtImage()) return;
    QImage& q = *(m_data->image);
    U32 count=0, max=(U32)(q.height()*q.width());
    U32* p = (U32*)(q.bits());
    U32 n;
    while( count>24) & 0x000000ff);
                // p[count] = RGBA
        count++;
    }
}

void Image::Convert32bitRGBAtoARGB()
{
    if(!isQtImage()) return;
    QImage& q = *(m_data->image);
    U32 count=0, max=(U32)(q.height()*q.width());
    U32* p = (U32*)(q.bits());
    U32 n;
    while( count>8)  & 0x000000ff) |
                ((n>>8)  & 0x0000ff00) |
                ((n>>8)  & 0x00ff0000) |
                ((n<<24) & 0xff000000);
                // p[count] = ARGB
        count++;
    }
}
