Does PXC_AddImageFromMemory() does any GDI calls internally?

[omascia]

You might help me, regarding an issue that started hitting me one week and a half ago (which I have documented in this other thread https://forum.pdf-xchange.com/ ... 44&t=22283), by answering this precise question :

- when I call PXC_AddImageFromMemory(), does this one makes *any* GDI call to do its work?
(I assume no).

- then, what about PXC_AddImageFromHBITMAP()?
(I assume yes).

Am I right about these two?

Thanks a lot!

In case of raster formats - no, we do not need GDI. But when you use EMF/WMF files we use GDI functions.

(I assume yes).

Yes, we must use them to obtain data from HBITMAP.

Pardon me asking, but are you sure about EMF/WMF, I do not see how this API could take EMF/WMF as input as it receives an array of pixels as input, which is raster in essence.
Anyway, thanks for the confirmation that this API doesn't use GDI. This helps us understand better why we work-around the GDI problems we had these last days when we take care of passing you pixels straight through this API.
