Is there any recommended way to copy an SDL_Surface * to clipboard? I see there are clipboard functions for UTF8 text, but how are other types to be handled?

From a quick google it seems that SDL only has clipboard functions related to txt. Furthermore, another google tells me that to handle image data in the clipboard you'll need to set some data flags to tell the OS that there's an image on the clipboard (on windows, at least). SDL probably sets the clipboard flags to text, so you'll probably have to write some platform specific code for this, or extend SDL (this is all a wild guess though so don't take my word for it).

There is one exception though: if you want to exchange data between two of your own applications using the clipboard. Then I would probably just convert the chararray in the surface to base64 or something, prefix it with a magic string, and then just put that in the clipboard. The other application can then just recognize it's a dandango-type textual image, and interpret the base64 string accordingly. A naïve solution, but it probably works.

This was my SDL_Clipboard prototype/proposal which included handling
image copy-and-pasting SDL_surfaces between native platform image
types. I never figured out or got help on the X11 backend though, so
it only works on Mac and Windows.

Maybe you can update it and finish it for SDL 2.0. (iOS and Android
backends should also be added which speaks to how old this thing is.)

Thanks,
Eric
