Yes, the pattern matrix (if present) is concatenated to the stream's initial matrix to get the transformation from pattern space to device space.

> The bar charts converted from PDF is totally a black area. The code is as following:
> {code}                 
> PDFImageWriter imageWriter = new PDFImageWriter();
> boolean success = imageWriter.writeImage(document, imageFormat, password, startPage, endPage, outputPrefix, imageType, resolution);
> if (!success)
> {
> 	 logger.error( "Error: no writer found for image format '" + imageFormat + "'" );
>          System.exit(1);
> }
> {code}
> I will attach the ppt and PNG files later
