Hi.

OS: Fedora 41 KDE

I'm looking for a way to execute a command in Linux that are capable to produce two new files and also the reverse transform.

I have tried and also read up on the topic, but I'm stuck and get nowhere by this point.


This is what I have done so far, I'm stuck on both methods

1. Install the G'MIC 2.9.6 - Flathub

This make the command 'gmic' available in the Terminal. I've tried to read online, and also ran '$ man gmic | grep -i -b2 -a1 fourier' to see if I could extract key info on how to, but the man page doesn't give an actual real life example on how to actually run the command. So I'm still stuck, unsure if this is even possible.


2. using the -fft flag on the magick command

The magick tool seemingly have a command to do fourier analysis on an image file. The actual command I used was this one for a sample photo 'magick Nokia3210_cover-grå.jpg -fft Nokia3210_cover-grå_fft.png'.

This seemingly works- it output two files (automatically adding -0 and -1 at the end of the specified file name). However at opening the resulting image "Nokia3210_cover-grå_fft-0.png" - it consist of almost all black pixels, and does not resemble the result from when I run the Gmic Fourier Transform filter from within Gimp.

This together with the issue of not being able (don't know) how to do the reverse transform using command line makes it so that I do not know how to progress from here, if possible.

I have updated pl_stroke_arrows to v0.7. Notable changes are:

• Arrow tails added, with 11 variants available. Combined with head styles and shapes, you now have 96 distinct styles to choose from.
  
• More robust with complex paths, and better error management.
  
• Option to switch path direction.
  
• Bug fixes.
  

Is there a BIMP plugin available for GIMP 3.04?  I installed the new version but it wiped out Batch Image Manipulation in the File menu.  Can't figure out how to get it back without reverting to v2.10.

It appears that our database had a small problem this afternoon. This has been fixed.

"We apologize for the inconvenience".

The management

I have two images of the same thing. The extent and alignment are the same. One is low resolution (ppi) and has been geo referenced. The other is the same image where the ppi has been increased and the image size reduced with the scaling tool. 

I don't want to georeference all those points on this new image. It seems like there should be a relationship between the x, y coordinates of the pixels of the two images so I should be able to calculate where a pixel from the old image will line up on the new image.

I thought it would be a simple ratio, but so far it hasn't worked. The points move but are off by a lot.

I have read that the scaling tool has a number of interpolation methods and that may influence this relationship.

Does anyone know anything about this?

I'm actually trying to load the points from the old image onto the new higher ppi image in QGIS. I'm not sure if it has any settings for interpolation method when doing this operation or not. From there is will be warped. The warping included interpolation methods, but I'm not there yet.


Here is some info on the two images:

My old low ppi raster is:
3772 x 1936 pixels
0.4517  x 0.2319 inches print size  (11.47318 x 5.89026 mm)
8350 x 8350 PPI

The new high ppi raster is:
10190 x 5225 pixels
16.883 x 8.708 in print size  (428.8282 x 221.1832 mm)
600 x 600 PPI

Hello !

How to stop Gimp from starting in full screen, please ?

Hi! Is there some way to make the dialogs that appear when, by example, you want rotate an image, float instead of be kind off docked, and they remember their positions? Is annoying when rotating or some other tools, the options of the tool become attached to the upper right corner. Usually it cover something i want to see. I need to detach it and move the window outside the canvas to be able to see what im actually rotating.

There is a Blender addon called "Animated Texture Brush" available from Blender's official extensions.

   

It let the user open an image sequence, where the name of the images are something like:

brush_01.png
brush_02.png
brush_03.png
.....

And then the brush randomly paints the tip in the stroke.

Hello everyone!
What a coincidence. Today, just now, a little before 3:00 AM, I was thinking about this phenomenon: eclipses, when I suddenly decided to explore the subject further. Even after a few seconds, maybe even 1 or 2 minutes, of looking at the lunar eclipse calendar and looking at the information about the next lunar eclipse, I realized it will occur TODAY!!
These coincidences leave me incredulous.

How can I explain such a coincidence?
Have you ever experienced a similar situation?

Oh! And just to add a little more information, the next solar eclipse will be on the 21st of this month (September 21st).

   

Hi! I read somewhere that tiff, and jpeg2000 can include the mask paths info in the file itself. Im working in scribus and looking the way to make the wrap around images the more easier possible. This would be a great thing, but appear that Gimp cant do that, but not sure if is possible in v3.
