Hexagonal grid plugin for GIMP 3.0

[Scallact]

Hi, this is the initial release of my python hexagonal grid plugin converted to the GIMP 3.0 API. The functionalities where also expanded, most notably with the sample sheet output, and a few bugs and calculations corrected.

By default, it creates an hexagonal grid, using a search algorithm for optimal rasterization. It can also output a sheet with multiple hexagonal grid samples, selected by quality, in a nice tabular format.

Requirements:
GIMP 3.0 (and probably later)

Intallation:
Extract the .zip file and place the pl_hexgrid folder inside your user profile's Plug-ins folder.
You can find the plugin at Filters > Render > Pattern

Excerpt from the readme:

Quote:This GIMP plugin aims to draw regular hexagonal grids that fit the pixel grid as perfectly as possible, avoiding some common artefact like blurred vertical or horizontal lines. This optimisation also ensures that each hexagon is exactly the same and symmetrical.

As no perfect fit exists between a square grid (pixels) and an hexagonal one, hexagons' proportions are slightly stretched. The amount of deformation depends on their size. The working size factor of the plugin is the apothem, i.e. the distance between the center and the middle of a face. The user interface presents a more understandable "width" parameter, a measure of the distance between two faces.

Hope it is useful for someone. The included help is very basic and a bit technical for now, don't hesitate if you have some questions.

Cheers!
