I never did but i know is possible just i have no idea how

what i need is scale a series of images each to all most commune wallpaper sizes
and save them in a new folder adding to the images names the size

a example to clear suppose that the first input, i the first image of the series is "Lysergica Caves" and is was in pictures/Lysergica.

from that i need

Lysergica Caves"-1920x1200.png
"Lysergica Caves-1600x1200.png
"Lysergica Caves-1680x1050.png
Lysergica Caves--1440x900.png
Lysergica Caves-1280x800.png
Lysergica Caves-1400x1050.png
Lysergica Caves-1280x960.png
Lysergica Caves-1024x768.png
Lysergica Caves-1280x960.png
.Lysergica Caves -here-custom-size

all saved in a new "Wallpaper" subfolder inside the original directory (if was C:/...Pictures/Lysergica will be saved in C:/...Pictures/Lysergica/wallpaper

obviously each image should be scaled with liquid resize to the size indicated in the name

do manually would be impossible but should be a way to do a similar batch
and i really need it

Also a scheme o python " Wallpaper Multiplier " script may be a cool solution
(obviously the script will depend from liquid rescale )

PS about saving have to indicate manually where would be not the problem, the problem i need to solve is how automatically apply Liquid Rescale as indicated

Could Gimp Scripter do this?

i have no idea

Photocomix, can you give us a link to the plug-in you want to run please because if it's possible for me to install it easily, then I'll have a go at writing a script.

Kevin

sure

Thanks.

As it has a very large number of parameters to set (26), I'm going to assume that the default settings are suitable (?)

Kevin

Almost: obviously "output" should be "new image"

for the rest
1 Masks- no masks (default)

2 Output -New images
Resize canvas -true
Also in "Output" options
would be nice preserve the option to scale back..nice but far to be strictly needed
(most of times i would not scale back )

PS instead another option would made the script even more powerful and flexible :
use Liquid Rescale AND/OR normal gimp scale with this options:
Max quality- do NOT respect image ratio

If that possible then the names should be slightly modified to avoid overwriting :
as from "image.png"

image_1600x1200_LR( same for other sizes ) if scaled with Liquid Rescale
image_1600x1200_Sif scaled normally (again normally BUT without respecting image ratio

You could try Imagemagick liquid rescale.

The liquid rescale function is not something that I am very familiar with apart from knowing it exists.

You would need one command per final image size along the lines of:

convert *.jpg -liquid-rescale 1600x1200! -set filename:orig %t %[filename:orig]-1600x1200.jpg

but it will convert a folder full of images. Not very fast.

I can see where parts of the image in the middle have been squashed. It has really squashed the top of the image. It would be a 'try and see' experiment to find out if acceptable.

Yes i know about the squashing but i like some possible effect, once you get why and when squashing occour then is possible dose it in a creative way...as below that is just on the edge of squashing (the 3wheel thingy was twice big )



And i plan to use mostly to create fractal wallpaper where distortion are lees relevant because the mind has not a reference

ouch! for you windows users.

Just got round to looking at IM liquid-rescale again and it looks like it is not yet implemented in windows, only linux. Just tried it in a WinXP and it comes up with an error.

sorry

Yes doesn't work

You don't seem to be having much luck with any Gimp-only suggestions.

Don't take offense, just throwing some suggestions into the hat.

Since you don't use linux and hence IM is not an option maybe something in java.

I am a fan of ImageJ and that has a seam-carving plugin.

Looking around, there is some code here http://code.google.com/p/java-imageseams/

Another java thought is this

http://www.its.caltech.edu/~justinj/cs176/HW1/index.htm
there is a link to the java executable and bottom of the page
"To invoke the program without a GUI, use java -jar SeamCarving.jar infile outfile forwardEnergy newWidth"

I can envisage a win batch file along the lines of
1. get a image
2. invoke the seamcarving.jar to reduce the width.
3. rotate the image so the depth is now the width (using IM )
4. invoke the seamcarving.jar to reduce the width.
5. back to the top and the next image

Almost certainly very slow, and maybe problem passing the filename as requested.

best of luck

ok i may even use linux, as a fact i have last kubuntu even if is long time i don't open it ,mostly because the wireless connection doesn't work and i can't use a wired connection
( If not seldom i am doing just now to update the OS but to do it i had to invade my old father room and privacy)

well i was hoping also for pajnicky but maybe he is too busy or i added too much requests in my last message..

And ok imagemagick may even solve for me even if to use it i must use the terminal but still i think that a gimp "Adapt to wallpaper" script would be very handy also for others

but is true you had given me all the pointers to solve i have only to switch to my linux partition and convince again my unconscious mind that the command line will not bit me, neither a typo (i always make typo ) will erase all the content of my HD

Just too say that I won't be doing this script. Work and life are too busy at the moment.

OK i'm trying to fix my Kubuntu (something wrong with the update, i can't get the permission to update even as sudo ) and then i will go with imagemagick

Looking at your Lysergica Caves images on Flickr, seems that the images will be mostly scaled up rather than down. That is going to rule out that little java application.

IM in linux still works, this is one of your largest published 1110x832 scaled to 1920x1200



maybe ok?

yes it is ok
I believe i must wipe out my kubuntu since i don't find anyway to get the permission (no even as sudo) to install a couple of files needed to update and the software and update manager went mad (they do not display anymore the pop up to give the permission to update, no way...and then they refuse to apply any change because lack of permission , i tried to use apt-get as sudo but even that refuse to install that damned couple of files )

Still not Gimp, but using IM and java.
This is just an experiment/proof-that-it might-work in Windows (a winxp machine I keep for video editing - had to install java). To keep things simple I had the jar file and the image(s) in the same folder. Just a batch file that takes one parameter the filename



If your original size is the same proportion as your Flickr image 1110x832 then some of the scaled sizes don't really need anything other than a regular rescale.

Tried the worst case with the above size 1920x1200, which needs to 'lose' 239 pix off the depth and the result was as good as the IM seamcarving function.

This is only a suggestion how to call the LQR (using python) in Windows
