Hy I would like a help to simulate painting my house, using Gimp.
I want to paint my house, but I would like to see on screen how it will be with diferent paints on walls and other details.
I would like instruction on the easiest way to make selectrions or masks I don't know exactly, so I can define areas like walls for one color and others for details like floor or roof or columns, etc..
Then, I how can I apply paint in a way I can still see the texture behind to keep it photo realistic. How do I change the colors in a easy way. And how can I get it as close as possible to the real paint?
Thanks a lot

| "Mouseclick" is not recorded in Shortcuts |

Gimp 3 on Win 11.
I would like to use a shortcut (living in my muscle-memory from Photoshop) 'Ctrl+left mouseclick' on the layer mask icon (giving me the selection of the mask).
But when I try to input the combination - it is not recognized in the Configure Keyboard Shortcuts section.
At the same time I can have a mask shown with 'Alt+left mouseclick' on the layer mask icon. But this key-combination (though working) is not shown as a keyboard shortcut in the configure section ("Show Layer Masks" has the status "Disabled").
I guess 'Alt+left mouseclick' somehow was installed with the PhotoGimp plugin. I have searched for the plugin's key-definitions file to maybe be able to edit the short-cuts there. But I can't find it. And the right way would be to make these changes from the Configure Keyboard Shortcuts option.
How can I get Gimp to accept and show the mouse actions in the configure section?

I went from 2.10 to 3 this year, and have never had a good experience with the Text tool!! I hate it!!
When using the on-canvas text editor, I select my text and type in a new font at the top, and select it, the font does NOT change!
When selecting a font and size from the left side tool panel, with my text selected, it has no affect!
When using the big Text Editor, my text is microscopic no matter what size I set the font to..
'Use Selected font' may work, but I cannot tell, because I need a microscope to see my text.
When doing any of these actions, I always have my text selected. This has pretty much been the same for me from v2 - v3 for the past years.
I remember years ago when it seemed to kind of work.
Does it work this way for everyone? Is there a fix for this??

| Gimp 3.0 get Metadata with Python |

How do I retrieve jpg metadata from a Python plug-in in Gimp 3.0?
I open a jpg photo and need some metadata. With Gimp 2 and Python 2 I used the plug-in "gimp_image_get_metadata".
My code was (abridged):
Code:
import xml.etree.ElementTree as ET
metadata = pdb.gimp_image_get_metadata(self.image)
dateTag = "exif.photo.datetimeoriginal"
date = self.get_metadata_value(metadata, dateTag)
def get_metadata_value(self, metadata,
metadataName):
ciName = metadataName.lower()
value = ""
rootNode = ET.XML(metadata)
for tag in rootNode.findall('tag'):
if tag.attrib['name'].lower() == ciName:
value = tag.text
break
return value
The plug-in isn't there any more in Gimp 3. Instead I find the class Gimp.Metadata. This class provides some methods for restricted operations, but none for my needs. I try:
Code:
metadata = image.get_metadata()
I expect to get an xml document, but I don't know how to look for it.
Is there a different approach?
My system: Mac mini (Apple M2), macOS Tahoe (26.0.1)
My Gimp: 3.0.6
My Python: 3.10

| Colorized Layer Reverts to Greyscale if I Add a Layer Above it |

I have some satellite imagery of the same area bur from different times. I want to show where development has occurred.
The satellite images are all the the same extent but come from different sources and look a lot different from one another. While the changes in developed areas is visible it gets lost in all the other differences in the images.
I thought it might be best to use edge detect with the magic wand to select the developed areas in another layer and then turn it to just black and white, then change the colors of that area to some other color. I also thought because the satellite images were quite variable in how they looked, some were nice and full color others were more black and white and some it looks like some tiles were color and others more grayscale.
I could do that. I later thought I'd colorize the base grayscale layer to green. It sort of matches what I'm trying to show and gets lost even in the full color images when I go to grayscale.
I find though that when I overlay the layer with just the developed areas with an alpha background that the bottom colorized layer loses it colorization. I read something about turning the alpha lock on so I did that for the base layer and also the top layer and that didn't change anything. It went from colorized back to grayscale.
Does anyone know why it is doing this and how to keep if from doing this.
For that matter, I described what I'm trying to do because I have to think this sort of thing has been done many times by others. Maybe there is another way that is easier or maybe that just works.
I have used GIMP on and off for quite a few years now, but never really for this sort of thing. I'm also using v3.06 for Linux. I think it is a flatpack build as well for what its worth.
