[osg-users] how to convert a QPixmap to a osg::Image ?

[Jason MacDonald]

This is what I do to convert a QImage to osg::Image:

QImage img
.......
    QImage glimg(QGLWidget::convertToGLFormat(img));
    osg::Image* osgImg = new osg::Image;
    unsigned char* bits = new unsigned char[glimg.byteCount()];
    memcpy(bits, glimg.bits(),glimg.byteCount());
    osgImg->setImage(img.width(), img.height(), 1, GL_RGBA, GL_RGBA, GL_UNSIGNED_BYTE, bits, osg::Image::USE_NEW_DELETE);
