Hello everyone,

I successfully inserted a print screen in a tablet screen. The only thing that bothers me are the hands of the person that holds the tablet. I just want the image I inserted to be under the person's hands. How can I do this? Could you pls walk me through the process (I'm completely new to Gimp so I need pretty straight forward/easy directions pls :)

Thank you!

Hi,

I am having problems when I want to export images to .JPG file (or any other format).

Shouldn't the extension of the file change automatically to the one I choose in the drop-down menu?

The way it is now, I have to manually change the extension every time I want to export the image, and if I want to export it, isn't it logical that I want to change the image type?

Regards,

This is my first project with python-fu.  I have a routine I need to do on hundreds of images, a few times on each image. 

What I need to do is

1. Select a color using pdb.gimp_image_select_color
2. Delete the contents of that selection

This is the equivalent of

1. Using the Select By Color Tool (Shift O)
2. Hitting the delete button on the keyboard


I can create the selection but I am not sure how to delete the contents within the selection. Can someone steer me in the right direction for what I need to do next or point me towards an example?

Many thanks

Hello,
Total newbie here and using Gimp for scientific purposes.  We are following some past work of scientist testing digital photos to determine vegetation cover (obstruction from view).  Two author groups used Gimp to analyze their photos (pre 2013).  I am unable to recreate their procedures and can't figure out on my own how to count pixels.  I have hundreds of photos of grasses and plants taken with a black backdrop.  What I need to do is find the ratio of black pixels (the black backdrop) to other pixels (plants).  I tried using Threshold to change to BW then using Histogram.  I 've also tried using just Histogram.  I've tried a bunch of different ways to get to a pixel count.  I'm either missing a step or two or am just not understanding the results I'm getting.  HELP!!!  I can send an image if that helps.
Thank you,
Mo

The included video and the title really explain it, I am getting pretty bad performance when moving and scaling an image in GIMP with an image that is only 1440p. I do not get these performance issues under Windows 10.

I had 4 layers and in one section, I wanted to create a mask that "drilled" down through 3 of the layers. It has been a while since I did that but I think that what I ended up doing was creating a selection from the layer mask on the top layer, then creating a layer mask from selection for the other two layers but I was wondering if there was a better way to do this. I tried grouping and the "chain" icon to see if what I did to one layer applied to the others in the group/chain but no luck.

Any suggestions?

Thanks,

Jules

I can open a multipage .pdf in Gimp 2.8.22 as layers and work on it without difficulty. When I try to save it as a .pdf, all I get is one page and the others are lost.  Is there any way to save a multipage .pdf using Gimp?
