Looking at some of the new tweaks in Gimp 2.10 and a non-photographic filter, Filters -> Map -> Panorama-Projection. (It is in Gimp 2.8 as a GEGL operation, but who ever looks there). An additional option Inverse-Transform

The dialogue looks like this, with nice on-canvas updating. WYSIWYG




Why am I writing about this not-very-often-used filter? You might have, once upon a time, used a Gimp plugin MathMap to produce similar results. Will MathMap still work in Gimp 2.10? Yes but you might have to do a little gentle hacking to provide the necessary library files that MathMap requires.

This in a Kubuntu 18 VM and Gimp 2.10 from otto-kesselgulasch/gimp-edge. The mini-planet filter.

I have a GIMP file that I created some time back. Fast forward to today, I am using a new computer which apparently doesn't have the font that I used in the design installed. When I open the GIMP file, the font is still applied within the design but it can't be edited and will not show the name of the font. Is there any way to identify the name of the font at this point?

Hello,

2 questions here.

How to rotate selection, be it custom or rectangle or circular?

How to easily draw ready shapes, like rectangle and circle? I haven't found them in the toolbox.

Thanks.

I have a gif which supposedly has an alpha channel. When I try loading it onto a site, it always shows an opaque black background. I would appreciate it if anyone could tell me what I'm doing wrong. Thanks.https://www.dropbox.com/s/wygkz0iqmqh0e2...2.gif?dl=0

Attached is a screenshot of what I'm looking at.  My avatar file has been chosen - but I don't know where to click next to upload it.  Clicking on the bottom button (Choose Avatar) brings me to a bad page.   Please help.

I need to reduce a file size to 100kb - but don't know how.  Attached is the current information for that file:  Please help me with the procedure so I can save the reduced size file as a jpg.  Thank you.

I am making a blank paintable map from a game's map that it uses to make the provinces in-game. I want to know how to make the border between all the different colours instead of individually selecting them and making a border.

Let's say I have an image.
I roughly cut out leaving a border of 20-30 pixels say.

How can I have the border of the image stretch out to the edges of the picture and blend into white?

See the image below. I intentionally kept the picture dark to illustrate what I want.



I've never seen it done anywhere - but I can't see why it wouldn't be possible?

Thanks.

Say I crop a picture.
On the left I have an edge that is 5 pixels - after my object.
I want to have a border around my object be 20 pixels say.

How can I stretch the edge and make it 20 pixels?
I used to do this in Photoshop.

As an example see the image below


Say I want to stretch the left hand side.
Ignore the shadows! This is just an image I took off the internet to help ask my question!

Thanks.

I am trying to do this project where I take a photo of my face every day, and I want to stabilize my photos using GIMP. In my first picture, my face is more zoomed out than in the photo I want to edit, so I want to shrink the photo I am editing to fit that. How can I change the size of a layer?
