Creating a paperback cover. Instructions from Amazon say:

Quote:Image color, size, and quality. Images should be in CMYK color to ensure your cover looks good in print. All images should be sized at 100%, flattened to one layer, and placed in your document at a minimum resolution of 300 DPI (dots per inch).
 
Flatten all transparencies. These can cause the file to print with missing or distorted content.

I was hoping for an update to this.  Have not experienced this before this latest upgrade.  You open the levels screen and it could take literally 5-minutes before it shows a histogram or your able to hit auto.  I have a gaming machine.  Maybe this has been mentioned 42 times already.

I am trying to call a gegl edge detect filter repeatedly in a while loop as here

I'm running GIMP 2.10.20 on Windows 10 on a 4K screen.

I searched for and found various GIMP mask tutorials but for some reason it never comes out right.  

I have a specific image that I'm trying to "enhance" with a mask.  BTW, this image is a copyright released image found here for any would-be copyright nazis out there.

I'm trying to get this image here.......




to look like this image here.........




As you can see the second image has a very light sort of sepia tint to it and I'm guessing they made a mask over the whole image.  So if I like the second image better then why don't I just use the second image?  I have a higher resolution image of this image than the one that I found online that's been masked and in addition to that the second image has been cropped and I want to use the uncropped image.  

Can someone give me detailed instruction on how to get the first image to look exactly like the second image by making a mask?  Thanks in advance

I have done this  thing for years so something must be wrong with my layers. I need to clean up the area in top left bit by bit.
I pasted a vertical piece at the top left of the image in the top layer. In this situation I usually clean up the excess with a brush in a mask on the side. I did as follows:
1. made a selection  from the image part of the layer. If I click once inside the selection it stays, If I click twice it disappears.
2. move to the mask
3.switch from selection to brush tool
4. selection in image disappears 
I am doing all this because I can't run the brush in a straight line.
The selection is large compared to the tiny area I need to remove, but I think that I am in the right layer.
I also tried a New from visible on top, selecting always from the image part of the layer of course, add mask, but selection disappears as I add the mask. Thank you.

Version 3.0.4 is running on one computer. Just installed the same version on another computer. The new install shows a big blank window. Is it possible to copy a file from the first computer to the second to avoid manually setting display preferences? Both systems run Windows 10.

Hi, I just set out to write a tinyscheme script that retrieves the list of files from a folder using file-glob and although it looks trivial I can't get it to work. 

the line in question is:

(let* (filepaths (cadr (file-glob (string-append input-path "*.png") 0))))

which always returns empty whether I place it in a script or type a version into the console. Gimp just tells me that parameter 1 to cdr needs to be a pair.
Yes, I have verified that the folder pointed to by input-path exists and that there is at least one png file in it.Permissions are ok (I can load the file explicitly)
I have tried unix style and windows style path separator: nothing works.

I can hardly believe something this fundamental is actually broken - is there something about my setup that is wrong? I have a standard 3.04 installation using the windows installer any insights are appreciated.

Using a paperback cover template, I created and exported the final PDF file. I need to create a paperback cover using a different template provided by the distributor (PNG). Is there a way to port the work already done into this new template and "massage" it?

Hi,

I use the python-fu-eval batch interpreter on GIMP 3.0.4 AppImage and have noticed some unexpected behaviour. As a trivial example,


User:~$ ~/AppImages/gimp/GIMP-3.0.4-x86_64.AppImage -i --quit --batch-interpreter=python-fu-eval -b 'if True: a="something"; print(a);'
something
batch command executed successfully


But if the "if" statement comes after the declaration of variable "a"

User:~$ ~/AppImages/gimp/GIMP-3.0.4-x86_64.AppImage -i --quit --batch-interpreter=python-fu-eval -b 'a="something";if True: print(a);'
batch command experienced a calling error:
Traceback (most recent call last):
  File "/tmp/.mount_GIMP-3bPBAmP/usr/lib/x86_64-linux-gnu/gimp/3.0/plug-ins/python-eval/python-eval.py", line 42, in code_eval
    exec(code, globals())
  File "<string>", line 1
    a="something";if True: print(a);
                             ^^
SyntaxError: invalid syntax

Similar problems arise with a "with" statement.

I don't understand this. Has anyone else noticed this sort of behaviour?

My OS is linux 6.1.0-37-amd64

Thanks.

The British Post Office is releasing a special series of 10 stamps honoring the British comedy collective Monty Python. Nice! Four of the stamps depict scenes from the film "Monty Python and the Holy Grail," which was released exactly 50 years ago this year. The remaining six stamps feature the members of Monty Python: Graham Chapman, John Cleese, Terry Gilliam, Eric Idle, Terry Jones, and Michael Palin.
When I'm walking through Bruges, Belgium, and hear a horse-drawn carriage approaching, I always think of the scene with the coconut. I'll say to my wife, coconut sound, John Cleese's coming. I've never heard a reaction from the tourists around me... Monty Python humor, a little different ?
