Out team would be interested in that too...

while rendering, the background of an pdf-doc is white. It would be good to set this to transparent or a color (like the back_color of PDFLayout)...

Hi,
you can change the pre-rendering background by editing the two vDraw methods of VCache class.
You can set the color you want in the first parameter of the two DrawRect methods, I suggest you to set the same color in the two methods.

You need a premium or professional license to do this.
