As my question to the developers mailing list got ignored: https://mail.gnome.org/archives/gimp-dev...00004.html I'll try asking our Resident GEGL expert, tmanni

When trying to use the gegl:bump-map command, I do not know how to specify the "aux" layer to use. Is this
possible? if so what do I need to do?

When trying to use the gegl:contrast-curves command I don't know how to format the curve parameter as
anything I try is crashing GIMP (issue #5607)

I am trying to correct the over exposure in this photo. I have tried method using levels, exposure, shadows and  highlights etc. 
Can anyone please tell me the best method to correct the exposure. I am interested in the dress and girl in the photo.

i click any where but not work

Background set to Not Visible but still displays.

I have project made up of two gifs and two pictures set on a background that is set not to be visible. Every time it cycles through the stack the non visible and transparent background wipes the images and then they are re-displayed as it works up the stack.  This gives a nasty flicker that I need to get rid of.  Any ideas on what I am doing wrong or need to change?

Thanks

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.
