remove alpha channel on export? |

I'm running OS 10.6.8, and using GIMP 2.8.16.
In attempting to export a file with a transparency background I get getting the file with a white alpha channel background that I can't delete or clear. Is there any way I can export just the image with a transparent background without the white? The original projects begin with transparency backgrounds and all the layers have transparency alpha channels.
Also, my Eraser works intermittently. I'm having to use selection tools and Edit>Clear instead. This works but can be time-consuming. Any suggestions on fixes?
Thank you so much for your help.
Cheers!

How to extend an Image from side to side softening the hard edge of image |

I use Gimp and Blender to make my Videos, I have an Animation of the Sun Series:
see https://www.youtube.com/playlist?list=PL...fvNkVm3m6c
As you can see from the Image below Original
![[Image: Sun-2013-01168-720.png]](http://lightwizzard.com/resources/home/lightwizzard.com/Light-Wizzard-in-the-Flesh/Sun-2013-01168-720.png)
The Corona or Radiating Fire of the Sun has a hard edge on both sides sometime, sometimes they extend up and down, but not much, and the few times this did happen I fixed them by hand, but the side ones do not look good.
This is a NASA public domain images of the Sun in AIA 193 4096x4096 format, with an Environment image texture of the Stars as background using Blender.
What I want to do is soften the hard line so it looks more like this:
![[Image: Sun-2013-01168-720-Soft.png]](http://lightwizzard.com/resources/home/lightwizzard.com/Light-Wizzard-in-the-Flesh/Sun-2013-01168-720-Soft.png)
I just did a fast Smudge by hand in GIMP, this was originally a Blender question.
There are over 33,333 images for one Year and I have over 6 years of images that I am working with, that is over 200,000 images, so I can not do this by hand in my lifetime since I am dying of Cancer my time is limited, I am old and have Arthritis as well, so it would be a very painful way to go out, and I might not finish it, so why start, but I wanted to finish this series, and go back and do years before the series started, which is 2010, so people can view the sun over a decade, but the hard edge looks bad, and I know there is a way to fix this, but I am not good enough at blender or Gimp to figure it out, I think I ask once a year, and try to figure out how to fix it, my guess is that I need to write a script that takes the edges of the images and blurs or smudges it side ways in an oval shape, but I know even less about it when it comes to automating edits in gimp, then I do about Blender, not even sure it can be done, no idea how to do that, anyone have any ideas?
I originally did the video in 1080, now I want to render it in 2160, since the originals are larger then the 3840, it should look good at 4k, but I want to fix this issue since it will take a long time to render all these images in Blender.
Thanks

Edit path bezier handle in wrong location |

I'm trying to edit a path in GIMP. When clicking on certain nodes, the bezier handles don't appear to be in the correct location. One of the handles is placed right at the point of the node, making it almost impossible to move the node without moving the handle.
It doesn't happen for all points, just certain ones.

Could this be a bug, or is there some other issue?

Linear Gamma RGB Color Space |

Blurring or blending between two colors tends to result in colors in the middle that are too dark. In Photoshop, there's a setting called "Blend RGB Colors Using Gamma" which solves this blending issue. In GIMP, I've heard some talk about a similar solution, but have not been able to find clear instructions on how to do it.
This video talks more specifically about what exactly the problem I'm looking to solve is. (The relevant bit starts at 2:17.)
