  snap to grid
Posted by: gimpygirl - 02-28-2024, 12:14 AM - Forum: General questions - Replies (1)

Hi

When you make a grid and then do a crop, the selection with the mouse snaps to the grid automatically when you reach a grid line.
Can this be turned off too?

  Selection deletion making layer turn transparent
Posted by: FolkFriend - 02-27-2024, 04:06 PM - Forum: General questions - Replies (1)

Hello all and thank in advance for your help with this unusual issue! I have been using Gimp for a very long time with no issues but recently whenever I create a selection using the fuzzy select tool and use the delete key to rub it out, I find that the remaining parts of the layer go semi-transparent. Can anybody tell me how to prevent this please?

Thanks!

  ofn-export-layers
Posted by: gimpygirl - 02-27-2024, 01:15 AM - Forum: General questions - Replies (9)

I use ofn-export-layers a lot. Super useful plugin!
I noticed a very strange thing in windows 10 , GIMP 2.10.36

When ofn-export-layers is running (writing files) and I enter text anywhere on my computer, it adds characters I don't enter on my
keyboard like: ~ and ' and many more. So if I write "test", it adds random character in "test" which I dont really enter...

When ofn-export-layers has finished, this strange thing dissapears and I can enter text normally

Also ofn-export-layers runs very slow. Is this related to this?

I wanted to ask if the developer can tell me what this problem could be and if ofn-export-layers can be made faster (if possible).

So I need to wait to enter text anywhere until ofn-export-layers finished his work.

  automate layer movement
Posted by: gimpygirl - 02-27-2024, 01:02 AM - Forum: General questions - Replies (19)

Hi

Referring to this post:

https://www.gimp-forum.net/Thread-Cut-sq...from-iamge

I use the method with the guides and 2 python scripts.

2 questions:

1. Is it possible to automate layer movement? The images all have the same size. The layer needs to be moved in order to fit the guides of size 150 px. Is there a plugin or script that can let me move a layer to a position by entering x,y values or something?



2. Is is possible for the ofn-export-layers to have {numUp0}.png appear automatically so that I don't need to enter it each time when i run gimp?

  How to create a gradient from a profile?
Posted by: grillp - 02-26-2024, 11:31 PM - Forum: General questions - Replies (1)

Hey All.

New GIMP user here.

I am doing  some 3D modelling/rendering and want to create a greyscale bump map from a profile...

The profile is for a scalloped panel, as seen here:

   

So I want to use that profile to create a grayscale bump map like this (Dark is lower, light is higher), that repeats in the y direction, but follows a path that is the profile I am after.. kind of like this:

   

I created this one using a feathered Border Selection from a single central line, but it creates, a peak at the top and bottom of the bump which is not what I am after.

I find that using standard gradients are too linear, and I would like to use a Bezier curve path as the source for the gradient. If that makes sense.

Any pointers would be appreciated.

Cheers

G./

Lightbulb Exported png files get about 100 times larger than expected
Posted by: Grobe - 02-26-2024, 11:16 PM - Forum: General questions - Replies (1)

Hi.

Ok, so first - trying to upload the xcf file failed because of file size, so the only file possible to upload correctly is this png export settings.

Here is the file description.

  • Layer 1 - importet PNG file, file size about 55kB
  • Layer 2 - same dimension and roughly same size, but not same image.
  • Layer 3 - New transparent layer.
  • The layer 3 mainly consists of small spots of non-transparent pixels created with clone tool, so it's just to add/remove some features of a map.
The problem is that after exporting this image file to png format, the resulting file size get over 6MB - that is about 100 times larger, I expected the output png file to be maybe around 70kB at maximum.


Edit : Solved while edit this post

Ok, just figured the solution. The image precision was set to 32 bit floating point, and by converting to 8 bit integer, the exported PNG file became a nice 77kB file.

I post this anyway in case somebody happens to stumble upon same issue.

  Tips for cleaning up a receipt image
Posted by: mattyp77 - 02-25-2024, 08:19 PM - Forum: General questions - Replies (3)

So I have a receipt that I accidentally dropped on the floor of my car. Didnt notice it and it got stepped on, dirty, wrinkled, and distorted but it turns out I actually really need it to make a return. And it cant be looked up by credit card, it was a cash receipt. So I scanned it, cropped it, converted it to black and white, and did a little bit of manual clean up. Already that did a massive amount of clean up but I would like to go a step further. A lot of the text is cracked and partly unreadable and the bar code has a crease through it. At the very least I would like the lettering especially for the transaction number to be crisp and readable. If possible I would also like to fix up the bar code. I wonder if I can actually get it to scan. So any tips for filling in the cracks in the text and cleaning up the barcode would be greatly appreciated. Thanks

**Note: For the image I uploaded I did block out specific details to keep it anonymous. Besides its only so you can see what Im working with. Not for you to do it for me. Thanks!

  Intro and a few questions on attached photo
Posted by: Danbor - 02-24-2024, 02:19 AM - Forum: General questions - Replies (10)

Hello all. I'm a beginner to Gimp and photo editing in general. I've attached a photo that I am trying to restore, and though there are many issues that I need to work on, there are two that I think need to be addressed first. The first, is how to correct the "light flare" in the upper and lower left corners. The second issue, is there any way to bring out more detail in the shadow under the trailer?

   I am using Gimp 2.10.30 with G'MIC-QT version 3.3.4. My operating system is Linux Mint 21.3.

   Currently I'm near completion of  the Udemy course titled "GIMP 2.10 Masterclass: From beginner to pro photo editing". Actually I've finished the training modules and am working my way through the tutorials at the end to gain experience with the UI. Seems to be a good course, but it's emphasis is on design and creation. Sadly, I haven't a creative bone in my body and no interest is creating digital designs. 
   What I do have is several hundred photos from family photo albums taken from the early 1930's to the turn of the century that I want to restore.
   Anyway, enough of my rambling, Any suggestions on coping with the bright spots on the left of the photo and the details in the trailer shadow?
   Thanks in advance!

  Batch export png to svg
Posted by: gimpygirl - 02-23-2024, 07:25 PM - Forum: General questions - Replies (8)

Is it possible to batch export png files (with transparent background) to pixel perfect svg files (a whole folder)? How to do this in gimp?


Example files: the exported png files from this

https://www.gimp-forum.net/Thread-cut-sq...from-iamge

PS: I don't know if gimp supports SVG. If not, what open source/free program would you recommend to do this on windows?
