Newby Question - Select by Color Tool |

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

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.

automating a filter |

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 |

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.

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.
