I'm not sure - I've never dealt with floating point image formats, so you would have to add conversions for them.

I guess 32FC1 would be converted to QImage::Format_Grayscale8 or QImage::Format_Grayscale16 (Qt 5.13).

Maybe 32FC3 could be converted to QImage::Format_RGBA64 (Qt 5.12)?

Once you've added the conversions you can use ASM::cvMatToQPixmap() to get a QPixmap.

It depends what you mean by "resolved" 😄 I closed the issue because I answered the question and there was no response (after 2 years).

I didn't add this capability (I've still never worked with floating point image formats) and the poster did not submit a PR for it, so it's not in the code.

I'd be happy to look at a PR for it though!
