I have an image premade and I want to UV map it onto my object.  However, there seems to be no way to "unfold" an object onto an existing image. it always creates that ABC squares map.  I need to see the correct image in the UV mapperizer so I can correctly lay out my UV coordinates.

HOW?

Hello.
I set the default layer preview size from Edit > preferences but it apparently does nothing.
I later learned on the web that there's another setting I could use - in the Layers window > little black arrow > Preview Size. This works but it lacks one size option present in the prefs: huge. This happens to be the only one I need.
The questions are:
What exactly does the option in prefs do?
How eventually do I get the huge layer preview size?

I have an image with about 300 layers. Layers are different widths. Lets say that the image (canvas) is 1000 pixels wide.
Layer no. 50 is 500 pixels wide. I run BRL on layer no. 50. The image gets cropped to 500 pixels wide.

The only workaround I have found so far is to copy layer no. 50 to a new image, run BRL on that, and then copy this back to the original image and anchor it. Clumsy and time consuming.

Any suggestions for a fix or an easy workaround?

Hi. I'm using Gimp 2.8.20. Running under Windows 10.
I just wondered if anyone has compiled a list of all the plugins and/or filters.
I might want to go through and try to understand how to use some of them.
I seem to learn best by trial and ERROR. (emphasis mine, of course)

   
I added a grass jpeg to this photo with Gimp, but didn't select the shadowed areas. What I'd like to do is to add the grass texture image to the shadowed areas, but maintain the shadow color. Is there a way to layer the grass jpeg under the shadowed areas and still keep the dark color?

Hi All,

I didn't know the older forum was closed so after reading the Pat David's blog I ran here to register myself, however I didn't get this part of your terms:

Debugging python-fu scripts

As Brian Kernighan wrote, "The most effective debugging tool is still careful thought, coupled with judiciously placed print statements.".

On Linux (and likely OSX) things are easy: if you start Gimp from a terminal, all the output from print statements in Python plugins will be displayed in the terminal.

But on Windows, the output of plain print statements cannot be seen, so you have two options:

Using gimp_message()

This is a simple method which is OK to diagnose small and local problems, but it is better used on code which is known to be mostly working.

• start the Error console dialog
  
• use gimp_message() instead of print (if the Error console dialog is not up, Gimp stops with a dialog for each use of gimp_message())
  
  

• by default Python doesn't look in the directory where your code is
  
• the registration code doesn't work in the python-fu console, if fact it makes it crash.
  
• taking the new version in account with minimal effort after editing the code
  
  

• while testing the function, comment out the register() and main() call in your python
  
• make sure your file name is a valid python identifier (no dashes in the name, for instance)
  
• start the python-fu console, make sure you have one single image loaded and enter:
  

• to run the function:
  

• if you edit the file, to reload the new version of the code:
  

• if your plugin function takes more parameters you have to provide them "manually". In most cases they will just be strings (text, but also file names, fonts, brushes,...) or numbers. The semi-difficult cases are layers and other images, because the parameter is an object, so you have to retrieve it with python code (obtain the other image in gimp.image_list(), for instance, or a drawable from image.layers and checking its name).
  
• to start afresh, just close and reopen the python console
  
• when done, don't forget to:
  • uncomment the registration code
    
  • remove the print statements... in Windows they can freeze your script if the total length of output is bigger than 4KB (because there is nothing to read it)
    

Hi,

First post on this forum.

I enjoy using GIMP.

I have a question about cropping and pasting as new layer.

When cropping a select part of an image using the fuzzy select tool and pasting it into a new layer, the layer boundary exceeds the cropped image size  - there is typically extra vertical space around the top and bottom of the cropped image.

This makes resizing particularly difficult because I cannot compare the actual size of the cropped image to that of other layers pasted into the image because of the extra space.

I can confirm that nothing else has been selected below the cropped image.

I use GIMP to crop photos of coins.
So I crop and paste side A of the coin.
I then crop and paste side B as a new layer. However GIMP adds extra space  around the image which makes resizing side B really hard. It would otherwise be as simple as resizing the layer/image of side B to match side A.

Any help would be appreciated as have not been able to work out why this is happening.

I used to be a  member (knotty) of the 'OLD' forum that went under. Wondered what happened! anyway a question. I'm inbetween Internet connections. So wondering if I can download the latest GIMP at a public computer (library) onto a flashdrive and then install it to my home computer?

Thanks! Carl

Hi! I'm a gimp newbie so sorry if this was already answered. I've been trying to animate pixel art on a 64 x 64 pixel canvas. My issue is that when I try and playback the animation it is really small. Is there a way of making playback larger or is the only solution to draw with more pixels?
