I was wondering if there were any issues using GIMP on Windows 11 with a 4K monitor? I'm planning on updating soon. Thanks for your feedback

Win 10/GIMP 2.10.38

Converting grayscale image to color.

I am trying to work out a way to convert a grayscale image to color.

If I open a grayscale image and convert to RGB with Image>Mode RGB, the image does not behave like other RGB color images.

For example if I then choose Colors>Color Balance and move the sliders the image color does not change where as with other RGB images the image color changes if I do this.

I've tried simply creating a new (RGB) image and copying and pasting the grayscale image to the new image. If the new image has a white background this works but if I create a new image with a transparent background it doesn't. Why is this?

I notice that if I create an image with a white background the color channels seem as expected, ie Red Green and Blue but if I create an RGB image with a transparent background the color channels don't seem to have any color. Why is this?

Is there a way I can convert a grayscale image to RGB color so I can use the sliders in Image>Color Balance to change the color of an image but maintain a transparent background?

Thanks

For some reason today Gimp started having some kind of bug which is affecting all of my images I try to edit, in which no matter what color I try to select and use, it defaults to 735b35 and I can't make it stop or change color. it seems to only be affecting the drawing tools such as pencil.

an example of what it's doing: I'm working on pixel art and I have black as the foreground and red as the background, the images are all in RGB mode and I've tested turning color management off, but when I draw the color is brown (735b35) instead of black (000000) and if I select a different color using cntrl, or the color dropper it still makes them all brown, the paint bucket tool seems to work as it will make the colors work correctly, I have also uninstalled and reinstalled and it's still happening so I am not sure what the issue is at this point.

I am at the most recent version of gimp 2.10.38 (Revision 1)

I have recently re-installed Windows 11 (for a 64bit machine) and consequently had to re-install GIMP, too. I currently have v2.10.38.

Previously, when I clicked [Save Defaults] it would save everything (see pic for settings) but when I re-open GIMP at a later date it is not saving the quality or the subsampling. Any idea why, please?

This pertains to Version 2.10.38 (64bit) of GIMP on Windows.

GIMP is running in Single Window mode.  I think I mistakenly clicked the mouse on something unintended when using tools in the Window/Frame displayed on the left side of the screen.  As a result Tool Options are no longer displayed in that Window/Frame.  I spent a good amount of time reviewing the User Manual looking for a way to undo this unwanted change but without success.  I did find and try selecting the menu option "Windows>Dockable Dialogs>Tool Options" but this did not appear to cause any change.

At present I'd expect that this problem could be fixed by reinstalling GIMP but I'd rather not do that.  Therefore, I'd be grateful for some help figuring out how to undo this unwanted change which I think would mean restoring the method of using Tool Options to the default setup (i.e., normal out of the box behavior).

I was originally going to try using procreate on the iPad but my boyfriend said that Apple stops supporting updates after 5 years and my iPad will be reaching the 5yr mark in September so he said doing it this way would be better. 

I mainly draw cartoons. 

I've never used any kind of digital art program before. Not even Photoshop so I'm finding it to be a bit frustrated that my art is coming out looking like something a 2nd grader did.

I'm still learning how all the tools and settings work but wondering if anyone has any tips/ticks to make things a little easier.

Sorry if this is not allowed.

Hi all.

Question to experts from scripts.

Everything seems to be simple. I know how to do it, but how to organize in a script (SCM) - ???.

What are we doing?

We take a small image and upscaped with RIS (Reverse Interpolate Scale).

Sounds? And what about practice?

In practice, we open the image and make 3 copies of the layer (in fact 2, but for comparison we leave the original layer). Disconnect the original layer. Let it be "Lena" (512x512).

For the middle of the new 3 layers, we make a "layer" -> "layer size". To see the difference more, I choose a simple bicubic interpolation. And I put the right size for upscape, for example 3500x3500. After that, I will do the layer back: "layer" -> "layer size" -> 512x512.

All three layers are prepared. Now the application modes: on the upper (copies) "multiply", on average (subjected to upscape and downscape) "divide", on the latter "normal". I combine visible layers (the original is turned off).

Now we make an upscape of the entire image (the original layer and united of the three): "image" -> "image size" -> 3500x3500. Including/turning off the layers, we look at the difference.

And what is the actual question? Everything is simple, no?

And how to organize the initial dimensions in the dialog of the window? And even more optimal option is the use of the initial dialogue of "size change". But how to do this in the script?

how to apply curves to multiple images?

Or in more general sense, how to apply a set of operations, in multiple images at once?
Yes, i know about batch mode.

Somewhere i read to import them as the layers of a single image, then how you saved them as individual images?

In the latest Cross windows x64 releases i noticed the Filters>development>python console and Script-Fu console are not included. Is this a bug?
Or is it just not included on purpose?
I have been using the latest Weekly Windows x64 installer and it seems fine. No missing menu items that is.

Just wondering why it's not included in the latest portable zip commits on GitLab.

Thx
