Tiff image overlay

Post by anasrallah » Sun Mar 24, 2013 11:16 pm

is there a way to load two images on top of each other in one gdviewer control?
I have some overlays saved in tiff format (old software) and I'm trying to migrate to gdpicture.
the tiff will be another layer of the jpg image.

if that's not possible can I have two gdviewers on top of each other and have the top one be transparent somehow?

Hi,

Unfortunately, neither option is available.
You can how ever implement what you want by combining the two images, and redrawing the resultant image in the GdViewer.
Here is the function that allows you to do that:

Hum, this is possible. The GdViewer is a container object, so you should be able to overlay or embed any object on it.

Kind regards,
