I have an image in Gimp, that has a layer mask made from a selection I made that is also stored as a channel. I want to use a transform action, (perspective transform),  on that image and to also apply it to the layer mask. When I do this it doesn't transform the layer mask. So, how do I do perspective transform on the image and its mask, (or selection) at the same time? 

Hello,

  Please forgive this newbie..probably silly...question, but is there a way to simulate a 30x optical zoom in Gimp?  I have an image shot on my Nikon D3300 at 18-mm of the entrance of the sanctuary of my church.  I need to zoom into the picture as though the image was shot from a 30x optical PTZ camera at its tightest shot.  Do I just zoom into the picture with "30 times magnification?" Thanks for the help.

Hi. I am a novice GIMP user. I have 2.10.8 and G'MIC. Retired, I look at GIMP as a way to stay "mentally challenged". One thing I like to work on are old family pictures, with some having the coherent noise patterns that I thought Fourier Transform could improve. I have watched youtube videos on G'MIC Fourier Transform, but the tutorial directions I've found don't align with what I see in G'MIC - Frequencies - Fourier Transform. Could someone direct me to tutorials or instructions that align with the Fourier Transform I see in 2.10.8?  THANKS for any information or suggestions!!!

Is there a feature in GIMP that can quickly complete/fill in patchy, incomplete line-work like in the image attached? The image is part of a scanned inked-in drawing that has been converted to indexed colors using a black and white (1-bit) palette. No other modifications were made to the scanned image.

Has something changed between 2.10.12 and 2.10.14 that would cause the Saul-Goode Luminosity Masks script to not work properly?

   

The attached .png is a shot of my channels window after running the script. The LL and LLL are completely black, while the D is totally white. I would expect the normal graduation from one step to the next.

I have downloaded a fresh copy of the script, run it through Tim's Constantize Filter and get exactly the same results.

Any help and advice much appreciated.

I have a lenovo ideapad flex. It comes with a touchscreen. I also have a lenovo active pen. I can draw with it on GIMP, but I can't get it to register pressure. Also, I tried to change my input devices settings, but I can't find an active pen in the menu. I think GIMP might think it's just the core pointer.

Does GIMP have support for this kind of device? It works with some other drawing applications that I've tried.

Hi,

I've read a dozen of forum answers about how to suppress "a color" but I can't find how to change a color range. Yet, the "rotate colors" tool enables me to beautifully target the desired range, but I can only change it to another color (not including white unfortunately). I can't change it to transparent.

I have many methods (including by moving sensitivity or selection type (composite, saturation, Hue, etc) oh each tool) to no avail, mainly because the zone has different shades of green and has hair accross it:
o select by color
o select with magic wand
o Color to alpha
o and several other methods I don't even remember now, probably all tools that can be found in "Colors".


What is frustrating is that I know from "rotate colors" that GIMP can identify this range.

Any ideas welcome!

Thanks a lot,

So, I'm trying to use this autosave plugin. I downloaded the file and unzipped it and put the .py file into the GIMP 2\lib\gimp\2.0\python folder. But when I opened GIMP, I can't find anything that says "auto-save" or something like it. According to the author, it should be in the "menu-image-bar under '<Image>/Extensions/Plugins-Python/File'". I don't know where this is and I can't find it. Please help, I don't know much about coding, GIMP or anything relevant in general.

On his web site Partha says he has not succeeded in building a stable, Mac-usable 2.10.12 version of GIMP. Since his builds are the only way I know to integrate nufraw into GIMP for the Mac, and since 2.10.8 crashes on my systems rather often*, I wonder if any macOS people are working on 2.10.12 for Mac?

Does anyone know?

Many Thanks,

Glen

Every time I open Gimp 2.10.14 the histogram defaults to the range 0,-0.  In fact, every time I open a new image this happens.  Is there any way to set it to default 0,255?  Also, am I the only one with this issue?
