Details

In ipng.cpp, the test for transparency used png_ptr->trans. This apparently only works for some transparent pngs. Some only send info to change png_ptr->num_trans > 0 when tRNS field transformation puts transparency in the alpha channel. Not that the channel or color type data is not updated in png_ptr, though it is in info_ptr.
