I'm attempting to start a Spriter dll plugin for DB, my only problem is that it's been a few years since I've touched C++. How could I go about loading images from the DLL and displaying them into DBP? I'm not even sure where to begin. I'd prefer not to rely on DB's image structure in terms of sharing their image IDs, same thing for sprites. Since each Spriter object will use multiple images, I don't the user to have to keep track of what image numbers are free and which aren't.

I'm sure I can look up tutorials on loading/manipulating images in C++, but where do I go from there?

DBP images use DX surfaces which once locked can be accessed directly. Here's a little snippet I played around with some time ago that might help you out...

Basically you lock the surface and grab the parameters of it including the pointer to directly manipulate the pixel data.

Seconded.

[Note to self: put C++ on a very slow back-burner yet again.]
