Photo 4-point perspective transform
Posted by: rich2005 - 01-27-2017, 11:00 AM - Forum: Extending the GIMP - Replies (4)

   

This is a little plugin ob-align.py by Oberon Leung, that is in danger of being lost, so this post to keep it alive.

There are other similar plugins and of course command line ImageMagick has a similar function.

However, ob-align.py, providing you are not too ambitious, is easy to use. 

A 4 minute demo





The plugin is attached, remember to unzip it. Pop it in your Gimp profile, in Windows, C:\Users\your-name\.gimp-2.8\plug-ins

Hi All,

I am trying to trace around this vette.  I have watched the video on how to many times, I have everything right until I go to the part where you select from path, then Invert, then delete and it should show checked background?  My keeps coming up white???  Could someone let me know what it is that I am not doing right?  I have a cnc wood carving machine and want to make a sign for my neighbors z06 Vette.  I would greatly appreciate any help you can send my way.

Thank you

Question Transform
Posted by: sallyanne - 01-24-2017, 09:49 PM - Forum: General questions - Replies (7)

Do you have a tutorial for this or can someone explain to me how I can move a picture to a distorted view. ie into the shape you want it and then anchor to  another layer
iwarp only shows the active layer and I don't understand Warp

Edit:- Looks like it may be the cage transform...just saw a video about it on YouTube.

  Select tools act as move tool
Posted by: reddbrad - 01-22-2017, 06:23 AM - Forum: General questions - Replies (4)

I'm using GIMP 2.8.18 on Ubuntu 16.04 LTS. I've been using GIMP for years and have never had a glitch. Today, I can't use the select tools. I click on one of the select tools and, instead, I get the move tool. I rebooted my machine. I tried resetting the tools to the default settings. I removed GIMP and reinstalled it but nothing has worked. Any suggestions?

  Gimp 2.8.20 ?
Posted by: rich2005 - 01-21-2017, 09:47 AM - Forum: Watercooler - No Replies

There is a Gimp 2.8.20 described here

https://git.gnome.org/browse/gimp/plain/NEWS?h=gimp-2-8

and via gimpusers (Alexandre Prokoudine)

"...We expect to ship v2.10 later this year with 16/32-bit per color channel precision, basic OpenEXR support, new and updated tools, UI updates, and many more changes..."

Maybe, providing they get their layer modes sorted.

  Levels histogram
Posted by: throwcode - 01-20-2017, 07:25 PM - Forum: General questions - Replies (7)

Hi everybody,

I'm using GIMP 2.8.18 and when I have an image selected and I open the Color/Levels view it does NOT include a histogram.  In my Internet searches there is always a histogram produced.  Is there away to turn this property on?

Your assistance is greatly appreciated.

  [Solved] Variables & math in entry widgets?
Posted by: jules - 01-20-2017, 09:23 AM - Forum: General questions - Replies (3)

Hello there,

I use calculations when, for example, I'm feathering a selection (e.g., 1800/3). And that works great.

But I'm wondering is there a variable that gives me the height or width of the image so that I don't have to enter that it's 1800, 5100, etc.  I'd like to be able to put in the feather selection input widget something like - HEIGHT/3 or WIDTH/3 or MAX_DIMENSION/3.  Is this possible?

Are there variables that you can use in the maths in entry widgets?

Many thanks,
Jules
