Regarding the dll, I would like to try it if you don't mind.
As I understand, the same bg color that I want to be transparent on my images should be set as the transparent bg of the form, right? If so, then black should be transparent.
Thanks for the support.
As a very humble suggestion, and obviously only if it can be done, I think you guys should think about implementing some visual feedback like that. I mean, Jarvis has a very strong appeal.I understand that it basically adds nothing to the core functionality of the software, but it's that cool thing that a software can have or not.
I'll take a look at Guile3D as soon as I arrive home. Thanks for the suggestion.
