Can one set the aspect ratio toggle switch from the 'Set Image Canvas Size' always 'on'  (locked) ?
   

Raw images taken with digital cameras contain raw sensor data. Such files can yield much better images than standard JPEGs but they must be “developed” using custom software, and this task takes time.
Raw files contain also an embedded jpeg image, already developed by the camera. This preview can be used to quickly show the image content, for example.

ERawP extracts the embedded previews from raw files and saves them in separate files. It can be useful if you need a reasonable approximation of the images and you do not want to spend time developing all the files. For example you might want to send the images to a friend by e-mail.

Dear Sirs
How do I "drop" the g-code plug-in into the GIMP plug in folder?

Regards

    I took a logo and put it into RGB mode, and then added an alpha channel.  I then cut the background color to make the logo transparent.  After changing the canvas size, I now have an unwanted border around the image.  How can I get rid of this border, so I can continue editing the way I'd like?

What would be the best way to separate the subject from the background of this image?

Hi am a GIMP newby, and was wondering if it is possable to Export a file that LibreOffice can use to add script to the file.

An eye-opening series on fortifications:

I have an image with a picture and a caption. I'd like to rotate the entire image so that the caption is perfectly horizontal. Is there a way to do this other than by eye?

Hi, I have a .gif file with 27 frames, all white background. Is it possible to clear the white background from all the layers without manually handling them one by one? Thanks.

Using Gimp 2.10.30 (32 bit) I was working on a 15,000 x 20,000  size image, and noticed that gimp was reporting the project size as 11.8 Gig (see attached).  Once I eventually exported the image... the final file size was only 135 MB.  But, I'm surprised that 32 bit gimp can count up that high?   What was actually going on behind the scenes allowing this to happen?




Additionally, this particular project involved my "quilting" together 10 fairly large tiles of a map, into a single image. This required SUBSTANTIAL moving, tilting, scaling, and redoing a large number of operations in order to get all the roadways to line up properly.

SO there is little doubt in my mind that I had a considerable amount of memory tied up, in the form  of "undo" operations.

Is there a good way to tell gimp to release "undo memory" during the course of a protracted multi stage project.

For example, once I had 6 of my 10 tiles edited and placed perfectly,  all the memory being held to save the "undo" operations up to that point, could be put to better use if released.

If that seems like an unusual ambition, consider that I came to this point the hard way.  The first time through the assembly of this quilt,  4 hours in and working on the 10th tile.....I did run out of memory....and the end result was not rewarding.  

So, this question is more or less a think-back to what I coulda/shoulda/woulda have done.
