I have searched for an answer, but can not seem to find a solution, so I apologize for asking if already answered. (I have read thru slicing, guilotine etc.)
I need to take different segmented crops of an image. Say my image is 100 tall by 2000 wide (100x2000 pixels)
How do I automatically crop an image 100x750 starting x=0 and crop every 10 pixels and save each image to file?
I want to crop all images 100 tall and 750 wide. 100x750
I want to crop every 10 pixels
image 1; x=0
image 2; x=10
image 3; x=20
;
;
;
image 126; x=1250
When it is complete I will have 126 images saved in a folder.
Thank You

Resolution keeps changing from saved resolution |

I typically use 150 dpi when creating my graphics, however, sometimes when I open them, the resolution changes to what translates to 150.22 or something like that, but it's showing in mm or something (can't pull up an example right now, and I can't remember exactly, as I'm not on my usual computer). How can I keep it set as always my default resolution and that it doesn't change to something else I never selected in the first place. But it changes the size of the graphic.
I have tried to look online, but all I can find are directions for just changing the resolution, which I know how to do. I just want a permanent setting for the preference. I did setup my preference for what I want my default starting document to be and it IS set for 150 dpi. However, it never opens to the size document I set it up to be.
I currently have version 2.10.20.

12 segments on circle |

Hi
How would you create a segmented circle?
Trying to create various watch faces. Is there a plug that automatically segments a circle into 12? End result is to have the numbers 1 to 12 uniformly placed around the edge of the circle (adjustable in the plugin?)
I know I can add a marker then duplicate/rotate it by % so many times, then add in the numbers manually, but is there a faster way to do this?
many thanks

cut fills area with white not transparency |

Hi,
I'm a beginner GIMP user - I use Linux Mint, GIMP 2.10.20
I opened a PNG image in Gimp. Then I used the rectangle selection tool to select an area I wanted to cut out. I cut it (Ctrl-X) and I tried clicking CUT in the menu. Instead of having the area that was cut be transparent, GIMP fills it with white.
How can I have it be transparent? like a hole
Thanks in advance
Sunny
