I'm not having much luck finding anything about this online. I scan drawings with a machine that runs on Windows, save the images and upload them on a cloud image-hosting site, download them onto my Linux machine and edit them in GIMP. I recently switched to saving the images as TIFF files before uploading and transferring them over, but all of a sudden I noticed that if I convert the TIFF to JPEG, it doesn't matter what the resolution is, GIMP automatically will change it to 72 dpi when I export the image as a JPEG.
I don't recall earlier versions of GIMP doing this, but I'm not sure as I only recently have been saving the images as TIFFs before converting them to JPEGs, whereas in the past I just saved as JPEG (I've been trying to avoid the artifacting that comes with working with JPEGs through multiple edits). So what gives? Is this a bug? Is there a patch or something I can install so that it doesn't do that anymore?
Just loaded GIMP and brought up a picture from my camera but could not find a way to file it so that I can attach it to my emails. I admit to being a little dense about computer use at times, but maybe some body can set me straight.
Hello, Looks like a lively and positive forum, glad to find it.
How to set the saturation for all pixels to 100%? Likewise for value. I'm leaving hue alone.
The hue-saturation tool does not do this, as far as I can see. My evidence is this: create a new image any size, fill it entirely with hsv 215,20,45. In the color tool, use the color picker to select anywhere, which puts this color into the color tool's swatch. Slide the saturation and value to 100 each. Then in the hue-saturation tool, increase saturation and value (called lightness here) to maximum each. Compare the image with the swatch.
Hi Guys. I am using Gimp 2.8.14 on Windows 10 and my projects keeps loosing layers after saving and reopening the project files. I save my files as .xcf and when I open it the next day there are several layers missing. The background layer and several pictures will be lost. The file size is still the same as the day before but several layers are missing. After a few attempts, Gimp will inform me that the file is corrupt.
Gimp 2.8.20
Windows 10
All of a sudden my ellipse select doesn't work. The rectangle select and lasso select work fine.
The ellipse looks like it's selecting, but nothing gets selected
I re-installed Gimp but it didn't help.
Any ideas, anyone?
Anybody else have this happen?

How to eliminate paper texture and pencil marks, but maintain the almost black to completely black ink from drawing scans?
B) LONG FORM QUERY:
I have some scans of drawings that I want to print on mildly textured archival quality paper. The problem is that the scans retain the texture from the original paper that the scan comes from. The consequence of this is that when printed on similar paper as the original drawing there is a doubling of textures – the printing paper and the pattern of the paper from the original scan. This leaves an undesirable, and rather fake looking, doubled texture effect in the blank 'white' areas of the images.
An added two-fold complication is that: 1) The ´black´inked areas of the images are not trully uniformly black due to the colour of the ink, erasing, slight errors and the original paper texture. I would, however, prefer that this subtle, uneven inking is maintained, as it preserves the handdrawn look of prints, but; 2) in the scans there is also the appearance of pencil ghosting that is barely visible in the original drawings. I do not want these pencil marks to be visible.
Any simple cutting technique will not do the job as some of the drawings are pointillist, and this cutting would need thousands of repetitions. Additionally, any simple single colour selection technique would not suffice as it is not only pure black, but also dark colours close to black that I need to retain.
So, overall, I basically want to maintain the original ink data, but eliminate the paper texture and the pencil data.
I have been experimenting with a number of different tools, such as the bucket fill plus custom pattern, color select, etc, but I am starting to become overwhelmed with the number of options.
One of my first GIMP tutorials is making a floating word - just a word with a simple 'shadow" giving the illusion of the word floating above its background
In that tutorial, the end result is a word (with a special texture) and a black "shadow" cast against the gree-ish background
Tutorial is easy enough to do, but i tried creating a white shadow.
So, at the beggining, instead of black background + white writing, i did the opposite: white background and black writing.
Needless to say, despite following exactly same steps, results varied wildly compared to the site:
1) at the point where they talk about "layer -> Anchor Layer", instead of obtaining white background with plasma texture writing, i get plasma background and black writing (!!!)
2) lower on the page, at the point where they say "Creating a drop shadow", there is green background and plasma textured text ....but in my case, i get plasma background!
So, despite following same steps, the results vary wildly.
How EXACTLY do i make it so the shadow cast is white instead of black ? (or any other color)
Please, use GIMP and tell me exactly what i need to do.
I posted the same topic a year ago onto a gimp forum, but I don't remember which one. As a result of the help I received, I was able to produce what I envisioned. It turns out that I want to do it again this year for a couple more of the kids in flag football.
Somehow, I cannot locate that thread anywhere on the net. I tried for so long and yet it seems like that thread completely disappeared. I even tried logging on to all kinds of gimp forums with a couple different email addresses I may have used, and none of the sites recognize them. It's as if there was another gimp forum, and that forum is now completely wiped out.
I saved the gimp file but when I open it, it's basically just the finished product. I can't for the life of me remember what steps I took to create the finished product. I really should have copied and pasted that thread and kept it in my email for future reference.
Basically I posted a thread showing these examples:
Actual bust:
A mock bust of Tom Coughlin:
This was my end result (I blanked out the kid's eyes and name due to privacy):
I got a lot of advice on how to do this and worked out really well. I'd love to be able to do this again.
Can anyone either help me locate that thread on the net, or provide me with some pointers on how to produce this look again?
