That was it! In checking while saving as a .png, the save transparent pixels was
grayed out. Took the original .jpg and clicked on Layers  Transparency  Add
alpha channel and erased some of the background to confirm. No more
whiteonly transparency. In all these years I suppose I've been lucky with
the many .jpg pics I've rendered because I've never encountered this before.

I can't begin to thank everyone for your rapid responses and helping me learn
something and resolving this perceived problem.

Again, thank you very much.

Mark

That would be strange, because the JPEG file format has no transparency.

[Gimp-user] Converting jpegs to pngs

2013-06-06 Thread 127markaz
It used to be that I could take any ,jpg file, then save it as a .png so that I
would have a transparent background in order to render the pic. Now, for
whatever reason, when converted the background remains white. What setting has
changed that I can no longer get a transparent background after the .png
conversion? Gimp V. 2.6.8.

Hi,

the current GIMP version is 2.8.4.
Can you try again with that version and tell us about your results?

Kind regards,

Sven

What about the PNG's setting (dialog box that appear, before saving). Can
you attach the screenshoot from that dialog box?
Maybe we can analyzing from that setting.

Make sure that the image has an alpha channel and that there are transparent 
parts before exporting.
