This produces pretty pictures and all, but the grid does not conform to its own settings, and considerable work needs to be done to it to make it the least bit accurate and usable as a drawing tool.
1. The size parameter should describe the distance from an edge to its opposite edge, starting at the designated edge of the image (top, left, right, bottom).
2. The origin should be specified in pixels from that designated edge of the image. The other dimension should have an equivalent offset you can specify.
3. The other dimension (east-west on a vertical, or north-south on a horizontal) should then be calculated from that value.
4. There should be an option to make the hexes either consistent (all the same width) or mathematically accurate (width varies by a pixel or so, since the ratio of height to width is half the square root of 3, an irrational number).
As is, not only does the size parameter NOT correspond to the actual size of the hex drawn, it can't be made to conform to a basic level of consistency. Frex, I specify I want hexes 120 pixels wide (horizontal), but they're actually less. I have to increase it to 138 or 139 to get close to the correct value of 120, but can't reach it - 138 is too small, 139 is too much, and if half-pixels were possible, even that might not be the correct position. The origin I could potentially correct by moving the layer, but this is an onerous extra step.
For purposes where precision is unimportant, this works just fine, but when I want specific hexes of a consistent size and origin offset, this tool is unfortunately of no value.
