Wow!!!! This is a really, really, old, topic. :)
Anyway, I'm having the *exact* same issue Fred is mentioning here, and I'm doing exactly the same steps: put two shapes on a page, select the two shapes, group - or don't - them, select "Copy as Image" after you right-click the group - or use the Edit Menu, it's the same behavior - and then paste - again, either by right clicking on the page or using the option from the Edit menu - it just pastes the shape group, and not an image.
I'm using the latest Desktop MacOS version (29.6.1) - universal DMG. I'm running the latest up to date MacOS Tahoe (26.3.1).
By the way: I've already tried the "
diagrams.net" web version - same behavior - and also on different browsers - Safari and Firefox. Exactly the same behavior.
Something that might help: if, in the group that I've selected there's an image as part of the selection, and I choose - either from the menu or from the right-click option - "Copy as image",
draw.io correctly copies the whole selection as one image.
However, if in the selected objects in the group there's not an image, then the behavior is exactly as Fred described, back in 2020, nowadays.
By the way #2: I've also tried creating a blank page only with the shapes that I want to be transformed as an image, but that doesn't work as well.
I'm feeling like somebody putting a message in a bottle, let's hope somebody reads this :) :)
If there's some other test I need to do in order to help on this, please, let me know!
Att,
Wolff
