  Newby Question - Select by Color Tool
Posted by: Figgley - 03-04-2020, 10:05 AM - Forum: General questions - Replies (6)

Hi All,

I've just joined the forum and had a quick search but couldn't find the answer to my question.

I am using the select by color tool to map light intensities from different photos. I can select regions of different brightness and can adjust the threshold level to widen or narrow the selection, all this I'm fine with. 

When I make a selection, the luminance is plotted on a histogram which shows the range of values the current selection is in. My question is; is there a way of setting the luminance values to drive the selection? I want to copy the selected regions and compare them so I want to ensure I have the same luminance values for the photos I'm comparing. 

[edit]: I am using 2.10.14

Thanks in advance

Mark

More industrial Wink  
Pulled out my old linux  Autopano (was an alternative to Hugin) & stitched 3 photographs for the top image. Otherwise touched up with Gimp 2.10.14 Bottom pair ? Just nice curves.

  Help with certain type of image noise.
Posted by: akovia - 03-02-2020, 09:54 PM - Forum: General questions - Replies (3)

I run into images like this over and over and just curious if I'm overlooking a better solution to repairing them. I'm only dealing with anime images, so a heavy handed approach with filters can sometimes work without completely ruining the image, but I was hopping there might be a better combination of filters or techniques.

These images do not have the distinct moire dots that are able to be descreened with some measure of success. My guess is the original sources were scaled down before descreening and this was the result? In any case, has anyone else run into images like this, and how did you deal with it?

   

This is my quick and dirty heavy-handed approach. I'm not sure that any approach would be able to preserve the finer details, but keeping that to a minimum while smoothing out the hard specks is certainly the dream.

G'MIC:
smooth [diffusion]
smooth [bilateral]
smooth[guided]
sharpen [inverse diffusion]

   

These images are usually from very old anime, and there just aren't better sources out there. I'm doing my best to make some of these images somewhat presentable for media centers, as new artwork will never become available again. (and I certainly do not have the talent to draw something that could pass for the original) 

Any input is most welcome!

  fuzzy select refuses to select background
Posted by: marigolden - 03-02-2020, 09:02 PM - Forum: General questions - Replies (4)

1. I'm on the right layer + nothing is currently selected
2. I have the fuzzy tool in "add" mode
3. Threshold is at the default of 15
4. I just reset the default values, closed the program and then reopened it and it's still doing this. 

It currently selects the image itself but not the background. Any idea what's going on?

  Plug-in Beautify
Posted by: LucivaldoGIMP - 03-02-2020, 04:25 PM - Forum: Extending the GIMP - Replies (14)

Hello everyone!

Dear rich2005, I really appreciate your previous help. Now again, I would like to know if the Beautify Plug-in has any problems with the texture-border? Every time I run it informs me that the texture was not found.

  brush engine creating hot pixels
Posted by: mholder - 03-02-2020, 10:52 AM - Forum: General questions - Replies (4)

Since 2.10.18 (and I think this problem may have started in 2.10.16) the brush engine is constantly creating hot pixels in areas with transparency.

The engine now does mip-mapping I think.  This may be the cause.  I even tried making brush sizes in powers of 2 (like 16,32,64,128 ...) hoping it might fix the issue.  It doesn't.

I may need some help joining the bug reporting site instead of just posting here.  Having full color bit map brushes is one of the advantages that puts Gimp ahead of Photoshop, and it now appears broken.


Tested same brush in 2.8

  automating a filter
Posted by: sierratango - 03-02-2020, 02:32 AM - Forum: General questions - Replies (1)

I would like to create a series of images by systematically varying just one parameter of a filter (e.g., changing the X1 or X2 input to Fractal Trace). As a GIMP beginner, it appears to me that for each new image, I have to re-open my source image, make all the initial parameter selections, change the value of the selected parameter, and then export the image. Is there a way to automate this process or at least to minimize the number of manual inputs?

  Unwanted behaviour in Text layers
Posted by: RrnR - 03-01-2020, 08:15 PM - Forum: General questions - Replies (3)

I have noticed an annoying behavior with text layers.  I have a project with several text layers.  Now and again, when I try to move the vertical origin of the text in a layer by picking up the size bar at the top, all of my text resets to a very small size when I release the sizing bar.  I have to then manually restore the text size it to the size it was (undo doesn't seem to work).  Other formatting such as bold or font color is retained.  I can't reproduce the issue at will, but wonder if it is related to text layers overlapping one another.

Posted by: Ofnuts - 03-01-2020, 01:45 PM - Forum: Extending the GIMP - Replies (2)

(03-01-2020, 10:10 AM)rich2005 Wrote: ... and a plea to Ofnuts, a new / updated plugin maybe with options (horizontal / vertical / both ) included. Might occupy your coffee break or perhaps not even that long Wink

The current version is written that way because it takes less time to remove an extra guide (one click-drag) than to select an option in a dialog (one click to select the option, one click to confirm the dialog). And if you only need one or two guides, it can be faster to position them by hand, for the same reason... So if we are talking about the 4 usual guides around the layer I don't think adding choices would be a great improvement, but I'm open to discussion.

If we add center guides (with the caveat that there is no center point if the layer dimension is an odd number) then it starts to make sense to not generate everything, but what the choices should be?
  • 6 check boxes, one for each possible guide
  • 3 check boxes, one for each horizontal/vertical pair and one for the center guides
  • 2 check boxes, one for the 4 outer guides and one for the two center guides (those can also be two distinct menu entries, since both would rarely be used together)
  • other combinations

And before you ask, IMHO the layer by percent is an awful design or at least it can be useful only in a few edge cases that anyone can solve with a calculator application. I'm convinced than in most cases the user wants N equally spaced guides and this is what the script should work with.
