I don’t know how to add that to the C code but I can compile and test it.

Maybe, we can try the same thing I did for Windows. Create and hide a real window and draw to it?

Michael, one thing weird is with no changes to the Mac code, it worked on my 10.12 Sierra VM yesterday. Maybe, VM vs. real hardware?

Unfortunately it didn’t seem to fix the Mac, since r72998 produces a black image.

Here is a question to the memory of the dev group. Does anyone know if m.nviz.image has *ever* worked for Mac or Windows?

If it has, any idea when it last worked? We could do a diff of the last working code and the current code to see what has changed.

Just for the record: m.nviz.image (most probably) never worked on Windows. On Mac (and Linux) it worked, but since certain version of operating system(s) and/or hardware it stopped working. It was reported to work even now (before the fixes) on an old (not updated) Mac. (In other words, the code was not broken on the way, but still needed/needs to be fixed.)

r72997 fixed m.nviz.image on Windows 10 64-bit. The off-screen bitmap buffer never seemed to work, so I changed it to an invisible window DC, which also supports hardware acceleration unlike a memory DC.



If not, it may take considerable effort to make this work.

Trying to figure out an efficient way forward
