Liquid Rescale Plug-in: step-by-step

Posted on October 1 2007 by Andre Noel

On my last post I wrote about the “Liquid Rescale Plug-in” for Gimp and published an image that I resized. Now I’ll show how to make it step-by-step.

First I choose a picture. The original size was 2048×1536 pixels.

Then I choose Layer > Liquid Rescale…

I changed the width to 1500 and “OK”:

Well, this is no good. The image was resized, but the plug-in didn’t know what was important on the image.

So I backed up the original and created a new transparent layer to identify what was important on the image:

On this new layer I filled with black what I want to preserve (I think it would be any color).

The new layer after painting (the white part is transparent):

Following, I selected the photo layer, then I choose Layer > Liquid Rescale…, but now I set my new layer as the area to preserve.

Finally, I executed the script and voi là!

OBS: I did the same thing on my three years old computer running Ubuntu Feisty (Athlon XP 2000+, 512Mb RAM DDR), and on my new computer on my work, running win XP (Pentium 4, 3.0, 512Mb RAM DDR2). On my computer the process was really really really faster.

    You could lower the opacity on the second layer, so you’d see what you’re drawing on.

    Hi Ori,

    It’s a good idea.

    Thanks for the step-by-step howto! I’d installed and tried the Gimp plugin, and found it completely unsatisfactory, although it seems to work alright for certain specific images. The pictures I tried all wound up badly distorted, like your first example here. I’ll give this a try later.
