<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This statement is no longer true. If the pixmap is not an ARGB32 pixmap, the function will crash. It will also fail if the image byte order doesn't match the CPU byte order, if the mask has the wrong size, or the mask isn't a bitmap.

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I think the logic needs to be the following:
* If the depth is 32, assume that the format is ARGB32_Premultiplied.
* If the depth is the default depth, examine the red/green/blue masks in the default visual
and try to find a matching QImage format. If there is no matching format, it's necessary
to do format conversion. x2rgb10 in particular is becoming increasingly likely,
and it's not supported by Qt.
* If the depth is not 32, the default depth, or 1, we simply don't know.
The byte order is found in xcb_setup_t::image_byte_order.
