Transparent Images for GDL UI's exported from Archicad

[GDL Enthusiast]

Hi GDL Experts,

I am wondering what the work flow is for exporting an image from Archicad that has a transparent background that can be imported into the user interface.

I can export an images from AC with Alpha Channel, however all four standard AC export image types come through with a white background e.g. *png, *jpg, *gif & *tiff (samples attached).

Using the following code

ui_pict "Test_Image", 15, 15, 140, 140, 1

The images come through looking like this:

Also is there a way to set the size of the image on export - the UI_PICT function calls for a specific size. When AC exports it seems to export the extents. I thought adding the red boundary would be a way to control the size but there seems to be a white border beyond this.

Is this what other people do or is there a better workflow for this?

Thank you so much in advance!

Hi Barry, hehe I was wondering if I was doing something wrong with the Archicad Export alpha channel not working - I had tried every export option without success. I am glad it wasn't just me... All the best for you and yours at Christmas!

You have it in all AC's, but it is also a part of GDL sdk that can be downloaded from Developers' site. It contains some examples and a manual for the tool btw.
