+    \value NoOpaqueDetection Do not check whether the image contains non-opaque
+           pixels. Use this if you know that the image is semi-transparent and
+           you want to avoid the overhead of checking the pixels in the image
+           until a non-opaque pixel is found, or if you want the pixmap to
+           retain an alpha channel for some other reason. If the image has no
+           alpha channel this flag has no effect.
