PNG exporting as black box when it had been exported correctly before
#1
I've been using the quick mask function (maybe that has some connection?) and tried to export the picture as normal in a png, which I've done before on this same picture, but this time it exported as a black box, just the color black filling up the whole image. I was backtracking some steps so there's both an undo and redo option available, as in it's in the middle-- could that be why it's exporting weird? It let me save it as a file while in that middle state so I don't see why that'd interfere with exporting the image.

When you are in quickmask mode and use File>Export, you export the selection mask, not the image. And if there is no selection, the selection mask is all black. I though for a minute that this was a 2.10 bug, but the 2.8 behavior is the same.

But it's not in quick mask modeSad Maybe that wasn't clear, I was just mentioning I'd used it on the picture in case that was relevant. But it's in a stage where it's off and done with, the background cleared with images neatly on an alpha channel

I think I know what is happening, goes back to an earlier post https://www.gimp-forum.net/Thread-How-to-merge-channels where you are
I'm doing a quick mask and kept "saving to channel" to make sure I wasn't losing anything..

Not the way to do it. Use a quickmask (or some other selection tool) to create a selection and save that selection as a channel.

Then you need to be aware of where you are Wink If you export an image be on an active layer in the layers dock.

Channels can save individual selections and can combine (or subtract) to restore at a later date, providing you SAVE as a Gimp .xcf file.

Not the best I have ever done but trying to explain here: https://youtu.be/fftRiOUwxAc Duration 4 and a half minutes Hope it helps.

Wow you're the greatest! I will look at this closely later. For this one I ended up just going with my later version
