  Newbie. Simple Box
Posted by: Jonyskids - 11-13-2019, 01:21 AM - Forum: General questions - Replies (2)

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.

  resizing an active layer
Posted by: Argos - 11-12-2019, 07:18 PM - Forum: General questions - Replies (6)

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'

  How to perspective transform a layer and its mask?
Posted by: daiappy - 11-12-2019, 01:54 PM - Forum: General questions - Replies (2)

Huh   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?  Huh

  Newbie question: Simulating 30X optical zoom
Posted by: briwillis - 11-12-2019, 02:15 AM - Forum: General questions - Replies (4)

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.

  Fourier Transform tutorials
Posted by: Leader344 - 11-11-2019, 07:01 PM - Forum: General questions - Replies (5)

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!!!

  Fixing scanned Ink Lines
Posted by: Hydro - 11-11-2019, 09:37 AM - Forum: General questions - Replies (5)

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.

  Saul-goode Luminosity Masks not working in 2.10.14
Posted by: david - 11-10-2019, 09:33 PM - Forum: Linux and other Unixen - Replies (9)

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.
david.

  No pressure sensitivity with touchscreen?
Posted by: helpme - 11-10-2019, 05:46 PM - Forum: Installation and usage - No Replies

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.

  Is there a "rotate colors" to alpha
Posted by: Mapsmaps - 11-10-2019, 01:09 PM - Forum: General questions - Replies (2)

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,

Maps

  trouble using an autosave plugin
Posted by: helpme - 11-10-2019, 02:49 AM - Forum: Extending the GIMP - Replies (4)

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.
