Class RotatedViewport

Namespace

EncDotNet.S100.Rendering.Scene

Assembly

EncDotNet.S100.Rendering.Scene.dll

Geometry of a rotated Viewport (issue #578). A rotated display is drawn by rendering a north-up cover — an axis-aligned viewport at the same scale and centre, large enough that the rotated output rectangle fits inside it — and rotating that onto the output about its centre.

Methods

NorthUpCover(Viewport)

The north-up viewport covering viewport once rotated: same centre and metres per pixel, with a pixel size that holds the rotated output's bounding box. Returns viewport itself when it is not rotated.

public static Viewport NorthUpCover(Viewport viewport)

Parameters

viewport Viewport

Returns

Viewport

Remarks

The cover's width and height differ from the output's by an even number of pixels, so its centre lands on the output's centre exactly, with no half-pixel shift.
