My own take on luminosity masks. While it pays its dues to PatDavid's canonical tutorial on the subject, it creates the same masks using a different and (hopefully) more efficient method that allows:

• to create a luminosity selection from the current layer in one single click (or one keystroke if you defined shortcuts)
  
• in a future version, to define your own masks

I've created a PDF portfolio using Gimp 2.10, but when I open the PDF in Acrobat, the fonts are all messed up. How can I fix it?

I am trying to make a template. 

I need a canvas of 2.6875" x 3.21875", I nailed it no problem

But then I need a box the creates a border that is 39" thick or 2.2975" x 2.82875"

I can not seem to define this box by these measurements.

Any help is appreciated and apologize for the simple question.

I have a minor problem. I have a group photograph that I'd like to frame. Unfortunately the photograph is in different proportions to the frame (It's wider in proportion to the height). In normal circumstances, I could crop to the correct proportion, but that would mean losing the people to the sides of the picture. Framing, as, is leaves an ugly band at top and bottom of the picture. In this case, a simple change is possible and easy, in principle. The foreground of the picture is grass. If I could add a blank area to the bottom of the picture, I could use the clone tool to extend the grass to the new bottom of the picture. It's sufficiently amorphous and out of focus, to add without any distinct addition. I've searched the manual, without success. I've a number of pictures which could be improved by such a solution, or variations of a solution.
Cheers

BTW, this is my first post to this forum, so, apologies in advance, if I've not done it 'by the book'

   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.
