            Description

            The xform transparency support will paint the xForm content stream to a buffered image if the graphics state contains an alpha value less then 1.0. The buffer that is created for this raster needs to be a fixed width and height which is derived from the xform's bbox. For some reason the bbox dimension defined in this document are huge and appear to be a side effect of some encoder that is is dropping in the integer max value instead of a limited size.

            I've added code to only create a raster if the bbox is a reasonable size, otherwise transparency is ignored the xform content stream is painted as per usual.

              Added check of the bbox size to make sure the raster can be creating without a problem. Marking as resolved.
