            Description

            A client has reported that they are having difficulty converting a few documents to image. During the capture process the user is allowed to pick one of the following capture type colour modes for the resulting buffered image:

            // type is a given method-parameter - the user can define the ImageType
                    // possible values:
                    // - BufferedImage.TYPE_BYTE_GRAY
                    // - BufferedImage.TYPE_BYTE_BINARY
                    // - BufferedImage.TYPE_INT_RGB

            There is a logo in the document in question that contains a gradient. If the buffered image type is gray or binary the batik library we use for pattern paint will fail. It should be relatively straight foward to catch the exception and use a solid fill instead of the gradient paint. A check for a newer version of the pattern pain class would also be another good idea.

              Updated the MultipleGradientPaintContext class to support Gray colour space model. This fixes the unsupported exception that was being through. The PDF content stream now renders correctly when doing a page capture to a buffered image of type TYPE_BYTE_GRAY.
