I have a high resolution and kind of large picture.  It is a panorama  made from several pictures.

I'm trying to use the foreground select to turn the background to alpha.  I thought I had it done, and when I went to preview it a message box popped up saying calculating unknown pixels and the hard drive was active for quite a while and then GIMP crashed.

I think this may have been because the background was basically the sky and I just put my foreground select lines along the edges of where the background and the foreground intersected.  However, it did mask the photo and allow me to use the brush tool, etc.

I thought I'd see if I could do it in stages and do just one corner, but I see the mask extended beyond where I had my Foreground Select lines.  So it doesn't look like that is an option.  I also tried a different picture and did connect all the foreground select lines and had brushed only part of the picture and then saved it.  It  did save, but I could resume editing where I left off.  Maybe I can but I am missing something.

I guess I could use Foreground Select on the individual pictures the panorama is stitched together from.

I'm wondering if there are any good techniques for doing this?

TIA

for what it's worth, I'm running GIMP 2.10.20 on a new install of Linux Mint 20. I installed the new GIMP because I couldn't find the image tool menu on the earlier version when I tried to use the fuzzy select tool.  It is the menu that has feather edges, mask and some other settings.  I couldn't find it on the new version either.  Maybe I just don't know how to display it.

MathMap - A Gimp plugin see: https://www.complang.tuwien.ac.at/schani/mathmap/ A new compilation tested in 'buntu 18.04 / 20.04 / Mint19 / 20 regular Gimp and Gimp-Appimage 2.10.x

Installation:
Download the zip from: https://u.pcloud.link/publink/show?code=...yMfS1SkfGy
Unzip and put the folder mathmap in  ~./GIMP/2.10/  and the plugin mathmap-full in  ~./GIMP/2.10/plug-ins (or the equivalent  ~./GIMP-Appimage/2.10/... )

There are dependencies which are probably not installed. In a terminal run

Hi
I am not expecting very professional work, just want to do it for fun. So I hope the
steps aren't too complicated...

I want to make an image of dinosaur walking around in the background of a place.


As a result, I think I'll first need to create a GIF image of dinosaur walking around.


And then, to put the GIF image on top of a static image (the place)

Would anyone suggest me the simplest way to do so??

Just for fun, not expecting too detailed.... Thanks

Effects such as Softglow and Bloom do not quite make it. The Akira Fuji effect selectively blooms only the bright stars in an astrophoto while leaving the fainter stars unaffected. This makes the constellations stand out easily. Any tips or plugins on how to make it work in GIMP?  Tried SBLUR in IRIS but that too it just does do it.

Hi, is there any method to preview a GIF before exporting it to a file ?  Also, is there any method transition effects like " dissolve ", " fade " etc while creating GIF ? I am hoping that someone has written a script for the same. Thanks.

If one has taken a picture with the vertical lines ok and the horizontal lines not parallel, then the 'Align to path' (ob-align.py) plugin can help : https://www.gimp-forum.net/attachment.php?aid=275

I am trying to repair this badly damaged b&w old photo. I have tried heal and clone tools , but they dont help much. The dress is supposed to be off white color. But using paint brush is ok, but when I change mode to overlay or softlight, the damages reappear.
I also trie wavelet decompse, but this also did not help.

Can you please suggest the best way to repait this photo. 
I have left out the face.

Hello,

I have a selection set and I want to fill it with the paint tool. I want the edges to be smooth so I turn on antialiasing:



But as you can see from the image, the edges still seem fully pixelated.

What am I doing wrong? How do I get antialiasing working with the paint tool?

Hi everyone

I'm new here; have been trying for a couple days to get this to work properly, and I've finally given up and decided to ask for some help, haha.

Basically, I'm attempting to curve an image (not a path, just an image) along a path. Curve bend seems to me to be the way to go, but I'm having all sorts of trouble actually using it...mostly because the grid with the points in the dialog box is so TINY. Like...idk if it's meant to be so small, but the grid is like...an inch long maybe? And the mouse movements I have to make to adjust are absolutely infinitesimal. My hand-eye coordination isn't good enough for that! XD

Anyway...the ideal solution would be to be able to load the points data from an SVG or something, so I could edit my path in Inkscape. If there's no way to do that, are there alternatives that allow me to edit the points either like...with the arrow keys or something, or in another program, or even (as big a pain as it would probably be) in a text editor or something? Is Curve Bend even the best way to do this? Tbh I'm still finding GIMP a bit counterintuitive in a lot of ways, so I have a difficult time with it sometimes.

Thanks for any help you can give!

Oh, and so that you don't have to check my profile--OS is Windows 10, GIMP version is 2.10.20 (revision 1). 

Hi All,

Not new to GIMP but never use it because I always hit a wall doing things almost immediately.  I really want to learn this hench my question and not giving up.

I have an image, a .png file exported from Inkscape, that has the attached pics for 'Layers', 'Channels', and just a little of the actual image.  From what I see and I think is the problem is the layer is the 'Background' and the 'image data' is all in the Alpha Channel only.
