\nI was initially planning to have a \u201cDRAFT\u201d watermark appear on the report based on a parameter.\u00a0 I thought an easy way to do that would be to add a PNG with alpha transparency as an additional image object, and show\/hide it as needed. This works great when exporting the report to a TIFF file, but it turns out the PDF renderer does not support transparency:<\/p>\n![\"Alpha](\"https:\/\/blogs.visigo.com\/chriscoulson\/wp-content\/uploads\/2011\/03\/exporttiff.gif\" "\\"Alpha")
