Preview on OS X and the Quartam PDF library. If you try to save a copy
of a file as PNG in Preview using "Save As" an "Alpha" checkbox
appears if the image is 32 bit. The Alpha checkbox is not present if
the image is not 32 bit. In the Quartam library you can't add 32-bit
PNG files so demo 6 doesn't work if the PNG has an alpha channel.
