Symetrize with LIVE PREVIEW

[MareroQ]

I started with fill-rotate.py by Tin Tran (because I like it and find it very useful) - can only be used for this purpose.

For comparison, standard Rotate with fill-rotate:




The rest is a small addition (although over 700 lines of code) by copy-paste (with small corrections required by Live Preview).

Can be downloaded from:

Source code Live Preview: Tin Tran
Based by codes Tin Tran fill_rotate.py and Ofnuts ofn-symmetries.py

I know they have eight eyes but the cat looks more like a spider now Thank you

[sallyanne]

Do I need the other two plugins/scripts as well? I cannot find it in my gimp. I have placed it in my user files in plugins and closed gimp down and restarted it

Hi Sallyanne,

This plugin requires nothing more than gtk2, Python-2.7 and Unicode support (which is all in Windows but may be problematic on some Linux distributions).

I didn't mention that it's very easy to create seamless textures using this plugin.

lol to your pic.
I still cannot see it. have move the plugin to another 2.10 folder plugins, refreshed. Closed gimp and restated and still no joy. Maybe I am just not meant to have it. Thanks for answering the other question.

Version 1.1.
Bug fix (logical):
"Mirroring through the central axis" does not require preparing a square - if the length of the side is not divisible (without remainder) by 2 - it is cropped by 1 pixel.

Sallyanne,
I feel inspired. Nice work (#9).

[MareroQ]

Thank you all for testing.

Changes in Version 1.2:
- added code for handling layers with transparency and the ability to undo "SYMMETRY BY DIAGONAL",
- add a space to the result name when you click OK (in case you want to run the plugin again).

Ver 1.3

Changes:
- for "SYMMETRY BY DIAGONAL" add pdb.gimp_selection_shrink (this prevents partially transparent pixels),

- added center guide and guides for created square,
- added option " Visible only TOP layer? (only useful if there is more than one layer and the active (initial) layer is with transparency)."

Guides can be useful when you want to move a layer the next time you use it.

When you use offset you must perform the following operation:
Layer to Image Size


The plugin currently does not work for a layer group.
