There's no reason to update for non-Windows users at this time.

Hello Carlos, I downloaded and installed your latest Windows release of this amazing plugin. I have GIMP 2.6.8 on Windows XP. The installation went well and gimp-lqr-plugin.exe is in the proper place in the plugins folder. But when I start GIMP, and it's "querying new plugins", a Microsoft Error Reporting dialogue pops up saying that "gimp-lqr-plugin.exe has encountered a problem and needs to close." I never send the error report because the computer I use is not connected to the internet, so after clicking "Don't Send", the dialoque closes and GIMP resumes a normal startup, but without Liquid Rescale showing in the Layers Menu. Do you have any ideas what could be causing this error condition? Thanks for your help and ideas!

GIMP 2.6 directory is C:\Program Files\GIMP-2.0

As previously announced, this time the translations and the help files should be working correctly (so you have no more excuses for not helping with the translations!)

Furthermore, the files you download are now true Windows installers, which makes installation (and uninstallation) safer and easier.

As always, there are versions for both standard GIMP and for GIMPPortable.

You'll find it in the Windows download page (Italian version here).

By the way, many translations are now very outdated and need to be updated! Please, consider helping with this if you can, thanks.

Here is the full list of new features:

• Added new option: output on new image
• Added new energy functions based on luma instead of brightness
• New edit masks mode:
  • Added edit buttons for aux layers
  • Switch to smaller, always-on-top interface while creating/editing aux layers
• Added info icons for aux layers
• Added text to some buttons
• No longer use extra layers to create the image thumbnail (this means no more "flashing" in the layers toolbox when staring the plugin or creating a new aux layer)
• Modified behaviour to make it more consistent:
  • After creating/editing aux layers the focus goes back to the layer which is to be rescaled
  • If an aux layer is deleted during or between sessions, it is not substitued by another one, and the corresponding setting is made inactive
  • Pressing "Back" in the interactive dialog saves the plugin values for later recalls
• Bugfix: finally fixed Windows localization
• Bugfix: fixed some minor issues arising when working on a new layer and going back and forth through interactive/non-interactive modes

It now requires GIMP 2.6 and the latest version (0.4.1) of the liblqr library, which you can find here.

Go get it from the Download page!

In case of the LOCALEDIR, instead calling "gimp_locale_directory ()" is sufficient.

If other data directories are also used by the plug-in (e.g. for registering the help file), these may need to be constructed, e.g. through:
gchar *path, *uri;
path = g_build_filename (gimp_data_directory (), "help", PLUGIN_NAME, NULL);
uri = g_filename_to_uri (path, NULL, NULL);
g_free (path);
gimp_plugin_help_register (plugin_name, uri);
g_free (uri);

Minor problem but should be simple to fix..

correct me if I am wrong, since I have ubuntu 8.10 and I currently try to compile the newer version.
First thing I am not able to add correct layer as 'discard features', I am trying to add the layer with (gimp-image-add-layer theImage theWLayer 0) where I put 0 also to the appropriate prop of the script-fu function, but even with setting the value to 4000 it doesn't work at all. I am running this from the commandline without interface.

I would also love to know if it is possible to extend the algorithm to rescale really big images, in doing rescaling per tile or hierarchically. since I end up with my 2gb ram on about 6000x6000(original size being scaled down) images. This is nice but for my current project I would love to do even much bigger images…

I just installed Liquid Rescale on latest version of Gimp on a computer running Windows XP Pro (x64 edition). When I tried to rescale an image, all the items on the Feature masks tab were grayed out. What causes this behavior?

Thanks.

I would like to ask if, and suggest that, the next version of Liquid Rescale will have interactive rescaling? I've seen others writing that Liquid Rescale will have an interactive rescale option — I know it already has somewhat interactivity in 0.6.1 — but, I would like something more like the interactivity in Photoshop.

I know this is a hard task, I just want to know whether the next coming version (0.6.2?) is the version that you might implement truly interactive rescaling.

On that note: When is the next version coming out? Or how close is it to being released?

Also, I would like to know if there is anyway I can "beta test" each version before they are released? All I would need is source code that can be compiled :)

Thank you.

Can it be done? Without being confusing.

The GIMP plugin will take advantage of the new features in the next version, but the performance can already be improved by just installing the new library version (you don't need to recompile the plugin¹).

Note for Windows users: I will pack a version with the new engine soon.

Calling error for procedure 'gimp-image-add-layer':
Image 'file:///home/bootch/LeefersFarmArt/Trial.pnm' (1) is of type 'gray', but an image of type 'rgb' is expected

I'm trying to dissappear (or remove or discard) an object.

I understand that this is not a high priority (greyscale a small portion of use) ( I can probably work around it) and that maybe it is a known limitation.
I searched for RGB in the tutorial and the manual but found no mention that discarding only works for color images.
It must be related to the need for a color (red) highlight for the selection to discard.

The installation file is a self-extractig executable. If you have GIMP installed in the default location, i.e. in the GIMP-2.0 folder under your main Program Files folder, just execute the file

INstaller can't work because that "the default location, the GIMP-2.0 folder in Program Files "does not exist:
Gimp folder for Gimp 2.6.x is called "GIMP-2.6" NOT "GIMP-2.0"

Something similar to install in 2.7, that installer will only deflate the content in a new bogus "GIMP-2.0" folder..

.only with obsolete version as 2.0 or 2.2 (not sure about 2.4) that may work

Thanks for you're Help.

Sorry for my English & my president…
I'm French

As for the previous version 0.5, the translations and help files will only work correctly in the standard version if the Windows Program Files directory name (which depends on the system language) starts with the letters "PROGRA" and the installation path is the default one. The PortableApps version is a little less problematic since it only requires that the installation path is the default one (something like L:\PortableApps\GIMPPortable, but the drive letter is not relevant).

Many thanks must go to François Collard for having compiled the plugin over and over until we managed to make it work properly.

• Added interactive mode: you can adjust the scaling size incrementally. Also, after the first computation the scaling can go in real-time!
• Scaling beyond 200% is now possible (the scaling is automatically divided in steps)
• The "scaling mode" was moved to the Output tab, and renamed; two new scaling modes were added
• Fixed non-interactive mode (previously buggy), and included three scripts to help command-line batch processing (so that you can easily automate liquid-rescaling operations on a large number of files from the command line)
• Split the auto-size button in two, one for width and the other for height

Go get it from the Download page!

http://www.gimptalk.com/forum/viewtopic.php?f=2&t=37395&p=268558

You might have to contact the plug-in's authors about how to call LQR from a script. The source code seems to indicate that when run non-interactively, the plug-in only expects five parameters, but its PDB registration demands 24 parameters.

Anyideas on how I can get this to work?

i tried removing the files from the plugin folder and put them (from the zip file) in my documents and settings folder under gimp 2.4
gimp started ok but still no plugin in the layers menu
i know i have done something rather silly and missed the obvious
but it sure has me stumped
any ideas where i went wrong ?
thanks

• one is an updated Windows version for standard GIMP users
• another one is for PortableApps users

The main new is that the translations and help files finally work to some extent in the Windows version - but only if GIMP is installed in standard paths:

• for the standard GIMP, the path must be C:\PROGRA~1\GIMP-2.0 (i.e. the Program Files directory, which is different in each language, must begin with the letters PROGRA - e.g. in Italian it is so)
• for GIMPPortable, the path must be something like L:\PortableApps\GIMPPortable.

In both cases, the drive letter is not relevant.

Note that the help file may still not be working in some cases.

If your path is different and you really want the plugin translated, you can also create those directories by yourself, in the same drive where you installed GIMP, following the above specified paths, and put there the relevant files (the ones under the share\locale folder).

Note: if you think this is silly (as we do) and know how to address this issue please contact me!

As for the previous versions, the lqr library is already included in the package, so there's no need to download it separately for Windows users.

but i am not reporting a bug in the wrong board but giving a good new, the problem was solved thank to my Flickr friend Francois Collard , that build new binary for windows .
I did a quick test, all seems working fine and even faster

At soon i get home i will upload ,and then edit this post to add a download link so you may test and, if you like , add to your download section.

EDIT here http://photocomix-resources.deviantart.com/art/Gimp-Liquid-Rescale-Windows-103271394 download button is at the left of the illustration
###########################################################################################
PS Francois send me also a deb package but at the moment i have no clear if is only for Ubuntu or for any Debian (i use only Ubuntu so i can't check)
anyway i will add that link too in a few hours from now so you may have a look

EDIT Deb are here, http://photocomix-resources.deviantart.com/art/Gimp-Liquid-Rescale-Ubuntu-103281999

As usual follow a full disclaimer, this debs worked fine on Francois and my computer, and are not yet tested by others

That is not a big problem for normal use( is quick rescale manually the result ) but become a problem for animations with hundreds of frames to rescale

Will be possible replace with something as "LqR+ Scale back to W" and/or "LqR+Scale back to H" where W and H are the Width and Height of the original?

That seems much more useful, because that will avoid additional
unnatural distortion , while "scale back " create always distortion except when locking imagine ratio

And result will have if not same imagine ratio of the original the same width or height (seems more logical for normal use…i believe most use liquid resize to change imagine ratio preserving the content )

BTW compatibility with GAP was on top of my wish list from the very first version i'm very grateful you added it
thank you !

I'm very interested with this "magic" plugin ;-) I've downloaded the Windows installation and I've followed the instructions but I don't find the plugin at any menu. I don't receive any error message at any time. Any ideas?

Thanks in advance for the plugin and the help ;-)
Sorry my english.

Paco.

List of changes

• Enforced 50% rescale limit in LqR+LqR back mode to prevent crash
• Enforced 200% rescale limit in non-interactive mode also
• Fixed some problems with new masks in greyscale images
• Fixed a bug about unnecessary conversion to RGB causing an error message
• Pressing the Refresh button caused the guess direction setting to be reset
• Cleaned up some clutter from incomplete translations
• Help images were converted from png to jpg to save some space

Another important bug, producing crashes in some cases, was fixed in the new release 0.2.1 of the Liquid Rescale library, go and get it as well.

Every rescale operation opens a GIMP message window with this message:

Calling error for procedure 'gimp-image-convert-rgb': Image '[path-to-image-here]' (49) is already of type 'rgb'

The image is indeed already of type rgb, so why convert it. Rescaling seems to be working, though. Just this weird message.

cheers, Ronald

I run Ubuntu 8.04 and had been enjoying ussing 0.3.0 with gimp 2.4 fine for a while. I'm no linux wizard, but I am able to at least install 2.0 of the lib and 5.0 of the plugin. I am resizing a small image experimenting with the new rigidity map and it consistently gives me "Plug-In 'Liquid rescale' left image undo in inconsistent state, closing open undo groups."

It seems to only happen when I use a seam mask AND a discard mask.

I'm kinda done experimenting with the rigidity mask until the problem can be fixed, but I will update if I have problems with other features.

Core engine

• Faster core engine, reduced memory requirements (see the news for the library release for more details)
• Introduced rigidity masks: rigidity can now be restricted to some image areas
• Added GAP support for animations: liquid rescale your videos for fun and profit!!!1!
• Introuced left-right/top-bottom balance

Interface

• Now discard masks are ignored by default when enlarging (but there's an option to go back to the previous behaviour)
• Added “reset” and “revert to last used values” buttons for the size, and an overall “reset” button
• The dialog now comes up with the last used values for the size, too (useful when doing tests and undoing many times)
• Added info icons
• Added russian help page!

Go get it from the Download page!

Note #1: (mainly for package maintainers) since the plugin development is now rather stable, the versioning system has changed: no “revision” will be applied any more to the tar file, micro version will be incremented instead. This applies to the liblqr library as well.
Note #2: as you may read in the library release notes, the liblqr can now handle images with a deeper colour depth than 8 bits per pixel. However, GIMP still works on 8-bits-per-pixel images, so the plugin doesn't exploit this capability yet.

This feature would especially make a difference when expanding an image. Currently the recommendation for large expansions that have a preserved area is to manually perform incremental rescales. Having this solution available would greatly simplify such operations.

A future direction this could go in is for feature removal. The user would no longer have to do anything except to determine which feature to remove. Using an incremental method, the idea would be to first calculate both the horizontal and vertical seams that would be removed, then to compare the "cost" of removing the horizontal seam to that of the vertical seam (this might need to be scaled based on aspect ratio, testing would have to be done. Also I'm definitely glossing over some details, but I hope my intention is clear). Whichever seam has a lower "cost" would be the one removed, and the next iteration would repeat this process until the discard area is removed completely. (Of course, for efficiency reasons, it should again be possible to remove more than one seam per iteration, where the given number of seams would determine the number of either horizontal or vertical seams to remove — not a combination of both.) Since the discard area has a high negative value, each iteration would remove a maximal number of discard pixels, so I would expect the entire process to converge quickly.

In any case, I don't expect the initial request to require much new development since it's mainly the same functionality in a loop. The "future direction" also doesn't seem like much of a change, since I presume that the only new code would be that which compares a given horizontal seam(s) to a given vertical seam(s) and determines which is better to remove. The biggest changes would likely be in the interface code.

I think this is worthwhile as long as it does not add too much code complexity; I would expect it to result in higher-quality images while also lightening the workload on the user (manually iterating for large expansions, taking time to determine the number and orientation of pixels to remove while discarding parts of an image, etc.).

I'm interested to hear what you think: bmintern A+ gmail D0+ com

Thanks in advance.

Plug-In 'Liquid Rescale ' left image undo in inconsistent state, closing open undo groups.

Just after rescaling the height.
I can see the Background LqR layer but at the same size as the original.

The plug-in work fine with smaller images.

Any hint ?

To install, just issue:

 yum install gimp-lqr-plugin 

i have download the source from this page and would like to install the Liquid Plugin into Gimp. I have Debian/Linux. I do ./configure, make and make install no Error Messages comes up. But when I start Gimp 2.4 in the Layer isn't the Liquid Plugin.

My first step was to load the gimp-plugin-registry package from my distro, but also there wasn't the Plugin. So I would try the Sourcecode. I found the help files under /usr/share/gimp-lqr-plugin and the binary in /usr/lib/gimp/2.0/plug-ins.

What must I do also?
