Meet the GIMP!

You can get a new version of the liquid rescale plugin of episode 14. Buralex mailed me that info - thanks! And he said that the plugin is indeed improved. I copy that part of his mail here:

I found it much easier to work with - you might want to retry the “cows” to see if you agree

Changes are:

* Faster engine
* Different use of preserve/discard layers
* Works on floating selections
* Rigidity introduced to control the seams Interface
* New interface with notebook
* Output to new layer option
* Visualization of seams in a separate layer
* Refresh button
* Create new layer button
* More sensible strength scale
* Added tooltips

New version changes the preferred way to use the plug-in.

Now you

1. Open the dialog and click “New” in “Feature preservation mask” group.

2. Temporarily move the dialog somewhere and use the brush to mark features to preserve in the new layer that LqR has just created for you. Note that color of brush has automagically changed to green.

3. Go back to the dialog and click “Refresh”. Preview will be updated, so small preview of the layer above will.

4. If you need to remove some features, do the same with “Feature discard mask”. Note that color of the brush will automatically change to red.

5. Define new size, strength for each mask, gradient function etc. Click OK.

New Rigidity option is useful when you have a number of “structured” objects (e.g. architecture, windows etc.) that have straight lines that should not be distorted.

Thanks for the mail, Alec! I’ll try that after I have worked out my email trouble.

Liquid Rescaling or Seam Carving - two names for a new way to change the proportions of pictures while keeping the content in shape. The Gimp now has such a plugin and I’ll show you how to use it. COWS? Well, they are important…..

Edit: There is a new version of the plugin out.

I promised some links:

• The plugin site
• The Video about this algorithm
• The paper with all the background
• The stuff about the importance of cows
• The Meet the Gimp! photogroup at 23

Don’t forget to make a triptych and post it in the photogroup. I’ll draw a winner for the one year 23Plus membership sponsored by 23 in show 16. So you have still time to Oct. 18 to submit an entry. The pictures there are already worth to be looked at.
