Rotated grids in C#
🎨 For halftone dithering and more.
This project provides an enumerator for creating grid coordinates at a specified frequency along a rotated grid. This can come in useful e.g. when you want to create halftone dithering grids for CMYK processing.
This is a port of the rotated-grid Rust crate. The following screenshot is taken from that repo; this repository does not contain any visualization code.

Examples
Enumeration on an aligned grid (0 degrees rotation). The points are evenly spaced by dx=2 and dy=3, centered inside a 10×7 rectangle. No offset is used.
const float width = 10.0F;
const float height = 7.0F;
var grid = new GridPositionIterator(width, height, 2.0F, 3.0F, 0.0F, 0.0F, Angle.Zero);
var coordinates = new List<GridCoord>();
while (grid.MoveNext())
{
coordinates.Add(grid.Current);
}
coordinates.Count.Should().Be(15);
coordinates.Should().ContainInOrder(
// First row
new GridCoord(1.0F, 0.5F),
new GridCoord(3.0F, 0.5F),
new GridCoord(5.0F, 0.5F),
new GridCoord(7.0F, 0.5F),
new GridCoord(9.0F, 0.5F),
// Second row row
new GridCoord(1.0F, 3.5F),
new GridCoord(3.0F, 3.5F),
new GridCoord(5.0F, 3.5F),
new GridCoord(7.0F, 3.5F),
new GridCoord(9.0F, 3.5F),
// Third row
new GridCoord(1.0F, 6.5F),
new GridCoord(3.0F, 6.5F),
new GridCoord(5.0F, 6.5F),
new GridCoord(7.0F, 6.5F),
new GridCoord(9.0F, 6.5F)
);
Enumeration on a rotated grid; in the example below, 45 degrees rotation are used:
const float width = 10.0F;
const float height = 7.0F;
const float angle = 45.0F;
var grid = new GridPositionIterator(width, height, 2.0F, 2.0F, 0.0F, 0.0F, Angle.FromDegrees(angle));
var coordinates = new List<GridCoord>();
while (grid.MoveNext())
{
coordinates.Add(grid.Current);
}
coordinates.Count.Should().Be(17);
coordinates.Should().ContainInOrder(
// First row
new GridCoord(0.7573595F, 2.0857863F),
new GridCoord(2.1715730F, 0.6715729F),
// Second row
new GridCoord(0.7573595F, 4.9142137F),
new GridCoord(2.1715730F, 3.5000000F),
new GridCoord(3.5857863F, 2.0857863F),
new GridCoord(5.0000000F, 0.6715729F),
// Third row
new GridCoord(2.1715730F, 6.3284273F),
new GridCoord(3.5857863F, 4.9142137F),
new GridCoord(5.0000000F, 3.5000000F),
new GridCoord(6.4142137F, 2.0857863F),
new GridCoord(7.8284273F, 0.6715729F),
// Fourth row
new GridCoord(5.0000000F, 6.3284273F),
new GridCoord(6.4142137F, 4.9142137F),
new GridCoord(9.2426405F, 2.0857863F),
// Fifth row
new GridCoord(7.8284273F, 6.3284273F),
new GridCoord(9.2426405F, 4.9142137F)
);
