Using GIMP 2.10.20, and I want to export an image with a CMYK profile, for printing purposes. I downloaded CMYK profiles from Adobe and set in Preferences. I can use one of the profiles (Coated GRACol 2006) to soft proof without a problem. Using the same profile in the Image - Color Management - Convert to Color Profile option, I get the error message "ICC Profile Validation Failed: Color profile is not for RGB color space".  I tried a few of the other profiles from Adobe but with the same results. I know that sRGB is what GIMP uses, but why is the conversion not working? New GIMP user. And if I can't do it this way, is there an alternative? Thanks.

I want to convert series of grayscale textual pictures from JPG to PNG.  Because of large number of pictures, I am using batching with BIMP.

Starting with 262k JPG file
- if I change manually I get 196k PNG file,
- if I change by batch I get 292k PNG file.

The difference is huge and I cannot figure what is wrong.  The one logical explanation I could come up is that when I use batch, I cannot set pixelformat.  In manual change I use default "automatic pixelformat".

Is my conclusion correct?  Is there a way I could convert to PNG by batch and get the same result?

Best regards.

Hi COMPLETE NEWBIE HERE, so as the title says , i want to make separate images out of one image of a car blueprint. the blueprint has got all the different views in the same image. I know i'm gonna have to use the crop tool , however i also want the separate images to have the same ratio w/o causing any distortions to the car views

Hi all, i am an absolute beginner in image editing. So i have a question  . I downloaded a free blueprint from a website but the problem is that image is super low resolution and the lines are not very clear. i have attached the blueprint. Could some one just tell me if it's possible to increase the contrast of those lines and make them clearer in Gimp. THANKS

I know this has probably an obvious solution, but I couldn't find one.
Searching about it didn't help, as the key words appear in many other topics, so I decided to create an account and start by asking about it.

I am using Windows 7, Gimp 2.10.14 and a HP LaserJet 100 color MFP M175nw printer.

The printer is configured to always print in black and white, but whenever I print from Gimp it prints in colour, even when the image is in greyscale.

What am I missing?

I also noticed that the "Image Settings" section of the "Print..." menu doesn't show all the available options, as I can see that there's a radio button option just visible above the bottom of window.

Thanks in advance.

I hope that someone can help. I wish to make the area outside of the writing in the attached image clear, leaving the black outline of the writing and the green in-fill. However, I can only change all of the green to clear or none of it. Is there a way to fill in the writing without doing the background as well?
   
Thank you.

Jamie.

I am having some difficulty with Gmic filters not functioning while using the latest Gimp AppImage. 

GIMP_AppImage-git-2.10.21-20200910-withplugins-x86_64.AppImage

If anyone else is using this version here could you tell me if a whole lot of your Gmic plugins that came with it are not working?  As an example, let's just pick the Artistic filters, maybe 5 out of all of them are functional for me.

I don't know if it's a Gmic issue, a Gimp problem, or an AppImage packaging problem and was hoping someone here may have some insight into it.

The lastest Gimp AppImage comes with the latest Gmic 2.9.2.

Anyway, I've still got Gimp AppImage version 2.10.19 that comes bundled with Gmic 2.9.0 and all Gmic filters work flawlessly with that setup, so it isn't any emergency or anything.  I'm just curious if anyone else has had this same problem.

whenever I try to select a small area with free select tool  and theen do heal selection through filter, I find an error message. It doesnt seem to  change even if I try to reduce pixels to  25 etc.

Can anyone tell me the reason. Please the screenshot
