exporting gimp head

[dumbass]

GIMP 2.10.32 was working perfectly. All of a sudden I can't export a head without a black background. I removed GIMP and re-installed. No difference. I'm stumped.

Re-installing Gimp is not going to fix anything.

More information is needed.

What format are you exporting ? Is it .png or .jpg or .tif or .gif or ...?

Did you remove the background leaving transparency using Gimp ?

Is the Background Color (under the toolbox) black or white ? (this is used by the alpha channel)

How are you viewing your exported image, a file viewer / Windows Image Viewer / or something else ?

This has worked fine previously. Exporting as .jpg. I removed the background leaving a transparency. The viewer is photo viewer. The background still shows up. I just want the figure I cut out with the lasoo tool with no background attached.

This is how I cut out and save a head, (or so I thought):

Layer

Transparency

Add alpha channel

Free select tool (lasso)

Move to starting point and click.

Click to join end location.

Double click inside the image

SELECT INVERT

Control X to remove background


FILE EXPORT AS

Nothing wrong with your workflow.

If you are exporting to jpg format, this does not support transparency, so do not bother with an alpha channel, it is lost anyway.

When you cut a selection, whatever is there is replaced by the BackGround Colour (BG) Make sure the BG is White. The same applies if you have that alpha channel.

Examples: 

   

For images that have transparency .png / .gif /.tif the BG colour also applies. Some image viewers will use this colour, some use the checker pattern.

Of course it was saving as a jpg caused the problem. It's usually something simple - if you know what you're doing. Thank you very much.

JPG does not support transparency so you could not have had transparent pictures in that format before

..but that was not the question.

At some point I had changed the output to jpg so I could export modified photos easily, and then plug them into Facebook etc.. I didn't realize that doing so would cause problems in other functions.
