from GIMP documentation I understand that GIMP processes internally all in 3x32b floating point no matter what bit depth is used.

What puzzles me most - sRGB is 8bit gamma corrected and if I import 3x16b TIFF, what happens to image originally exported with ProPhoto RGB???

is sRGB just for preview and all available data 3x16b are used for processing anyway, please?

I do not know how to explain it, hopefully you understand.

I am a newbie with GIMP 2.10.12
I am trying to remove the distortion introduced by glasses
I have come across this tutorial for photoshop
Basically the way I understand it:
1. Load image on layer 1
2. Select area inside eyeglass
3. Paste in new layer 2
4. Add layer mask to layer 2
5. Stretch image on layer 2. Layer mask should "restrict" the visible area to the original glass area

Well I am not getting it to work. Sorry I am pretty sure this is basic
When I stretch the image the layer mask is not covering anything. Appreciate any assistance...

I have installed Ubuntu18.04LTS subsystem in Win10. Gimp are also installed and updated.


the gimp error messgaes:
(1) when I open gimp with the code: "export DISPALY=:0.0, gimp", an error message will be shown in the Ubuntu terminal, as shown in the below,

Failed to execute child process “dbus-launch” (No such file or directory)
(gimp:1109): GLib-GObject-WARNING **: 10:18:49.757: g_object_set_is_valid_property: object class 'GeglConfig' has no property named 'cache-size'
/usr/bin/dbus-launch terminated abnormally without any error message

(2) when I would like to read a image(gimp can not open .eps, .jpeg, but can open PDF file ) with gimp, a gimp message will appear as the following,
Opening '/home/qixycn/P1structure.eps' failed:
Permission denied

I truely hope someone can help me solve these problems. It has troubles me about a week. I'm so frustrated. Thank you in advance.

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'
