StackFaces¶

Namespace Nfty.Model in assembly Nfty.Model.

public sealed class StackFaces : IDisposable

The two face pictures of a risen stack: what the front and the back of each column show, each taken from the layer that OWNS that face by the union rule, plus the seam where a column's wall switches from one owner's color to the other's.

Remarks¶

Owns both images. Non-solid pixels are clear in both. For an all-paper stack both faces equal the art and every seam is 0.

Properties¶

Back¶

public Image<Rgba32> Back { get; }

What the back of each column shows.

Front¶

public Image<Rgba32> Front { get; }

What the front of each column shows.

Height¶

public int Height { get; }

Height in pixels.

Width¶

public int Width { get; }

Width in pixels.

Methods¶

BackColored(int, int)¶

public int BackColored(int x, int y);

How many voxels, counted from the column's back end, take the back color; the rest take the front color. 0 on a non-solid pixel.

Parameters

x (int) - Column.
y (int) - Row, 0 at the top.

Returns. The voxel count.

Clone()¶

public StackFaces Clone();

An independent copy; the caller owns it.

Returns. The copy.

CopyRegionFrom(StackFaces, Rectangle)¶

public void CopyRegionFrom(StackFaces source, Rectangle area);

Copies a rectangle of another set of faces over this one, in place (the same size).

Parameters

source (StackFaces) - The faces to read.
area (Rectangle) - The pixels to copy; clipped to the picture.

Exceptions

ArgumentException - The faces are another size.

Dispose()¶

public void Dispose();

Disposes the front and back pictures.

Uniform(Image<Rgba32>)¶

public static StackFaces Uniform(Image<Rgba32> art);

The faces of a single picture: both are the art, and the seam is 0.

Parameters

art (Image<Rgba32>) - The picture; cloned, not taken.

Returns. Faces the caller owns.
