Symmetry Tile

elfnor · **Joined:** Jul 05, 2014 **Posts:** 8

I've just finished a new plugin also based on the old Xaos Terrazzo. It works in GIMP 2.8.

This plug-in takes the selection from an image ("cell") and produces a new image according to one of the 17 plane symmetry groups . These are also known as wallpaper groups or plane crystallographic groups.

Basically it rotates and or flips copies of the cell, combines them to form a tile and then copies that tile to fill a new image.

I've just uploaded it to gimpscripts.

It can also be found on the symmetrytile repository on github under the user elfnor.
There are also example galleries avaliable, and more info on my github blog.

Sorry as a new user I can't give links.

Enjoy!

Installation

Requires GIMP to be installed.

From within GIMP find out where your plug-in directory is:

Edit>Preferences>Folders>Plug-ins

For Linux the plug-in directory will probably be ~/.gimp-2.8/plugins Copy the file symmetry_tile.py to this folder and make it "executable". To do this: select the plug-in from your file browser, click properties and check the box "Allow executable" under the permissions tab.

For Windows the plug-in directory will be probably be C:\Users\username\gimp-2.8\plug-ins. Copy the file symmetry_tile.py to this folder.

Restart GIMP to activate the plugin.
Usage

Select an area on an image using the rectangle select tool. Start the plug-in via Filters>Render>Symmetry Tile

You should see the following dialog.

Thanks Graechan for the links.

The plug-in should be on the menu as:

Filters->Render->Symmetry Tile

It will be greyed out unless there is an image open.

The results that I see on your website look a heck of a lot better then Multi-tile ever did. Why do you guys continue to want me to un-install GIMP 1.2.4? lol

I will try it out later when not so tired (work weekend mids; about to hit the sack). Thanks Elfnor.

I new it would not take long for you to notice this plugin Lyle, maybe Elfnor or someone could move it to it's own thread

to GC and thanks for sharing the script. It's available here:
http://gimpscripts.com/2014/07/symmetry-tile/

The results I'm seeing from the script are excellent. :bigthup

One suggestion is to check to see if there is a selection and if not, select all. If there is an alpha channel in the layer, perform "alpha to selection". This plug-in generates a warning error if there is no selection, so perhaps using these defaults would be a solution to that issue..

Just can not get results.

I tried over 7 times, changing settings, and all I get error messages.
I do not know what I might be doing wrong.
Finally tried the same image that the Graechan used in post # 8, and also received another error window.

Thx all

Whether using select all or a rectangular selection care should be taken with setting the width and height settings,
they should be divisible by the image or selection size used (x2, or x3, x4 etc.),

or the result may not come out, if your width and height are to big try scaling the image down first

Interesting script yielding some beautiful results. Thanks a lot!

when creating diagonal tiles [parallelograms], however, the seams are shown

Akros you must make a rectangular selection first or 'select-all'

K1TesseraEna very impressive results especially the second one :yes

Thanks elfnor and GnuTux. That is a very nice script. :tyspin

I tried it with a poster I did for summer season.

Thanks everyone for trying this out and for the feedback.
Looks like I've got a few things to fix:

Graechan:
The height and width must be a multiple of the same number. I'll loook into this. I must admit, all my testing was with square images.

Akros:
Currently you must make a rectangular selection before running the plug-in. GnuTux's suggestion of changing the plug-in to use the alpha channel if there is no selection, is a good one. I've also not tested the plug-in on layered images etc. only on jpg, png imported directly.

Do you still have a problem if you leave the height and width at 500, and select a small (100 x 100) section of a jpg opened in GIMP, and then run the plug-in?

K1TesseraEna:
Seams in the images from non-rectangular cells.
I thought I fixed that, its rounding versus truncating floats to make integers, and whether to grow the selection before the copy and paste. I'll look at that.

Elfnor I was trying to impress on people the need to be aware there is a connection between the selection size and the output size selected
but you have definitely brought your plugin to the right place for testing and constructive criticism

Graechan · **Posted:** Mon Jul 07, 2014 3:30 am **(#19)**

If your troubled by the transparent spaces try running RobA's 'Fill-Trans' until fix is made

Interesting tiler. Thank you elfnor. I went through all of the default presets and there are some good ones.
I have a couple patterns here I have made with it and one text example.
