Is the problem in my setup? Here's how I'm setting up the creation of an
xobject:
//Set the color
highlight.Color = BaseColor.YELLOW;
//PdfContentByte canvas = stamper.Writer.DirectContent;
PdfContentByte canvas = stamper.GetUnderContent(1);
PdfAppearance highlight_ap =
canvas.CreateAppearance(rect.Width, rect.Height);
Is the GetUndercontent basically adding this object to the page content?
What should I use instead?
Thanks!
