如何转换IplImage(OpenCV)到ALLEGRO_BITMAP (A5)快速

Question

是否有最快的方法将IplImage类型从OpenCV转换为Allegro 5.0的ALLEGRO_BITMAP类型?X比把每个像素从一个像素到另一个像素好吗?

像这样的2个for循环:

void iplImageToBitmap(IplImage *source, ALLEGRO_BITMAP* dest) {
    if(source!= NULL && dest!= NULL) {
        al_set_target_bitmap(dest);
        int height = source->height;
        int width = source->width;
        int x,y;
        for( y=0; y < height ; y++ ) {
            uchar* ptr = (uchar*) (
                source->imageData + y * source->widthStep
                );
            for( x=0; x < width; x++ ) {
                al_put_pixel(x,y,al_map_rgb(ptr[3*x+2],ptr[3*x+1],ptr[3*x]));
            }
        }
    }
}

Answer 1

使用al_lock_bitmap获取ALLEGRO_LOCKED_REGION，然后按描述设置像素数据。然后用al_unlock_bitmap解锁
