Syntax

public struct CRTImageRegion

Remarks

Some pipelines allocate their render textures at the largest size used so far and draw the current picture into the lower left part of each one. The default region means the picture fills both textures completely.

Fields

SourceOffset

Where the picture starts in the source texture, as a fraction of its size.

Declaration

public Vector2 SourceOffset

Field Value

Type	Description
Vector2

SourceScale

The fraction of the source texture that holds the picture. Zero, the default, means the whole texture.

Declaration

public Vector2 SourceScale

Field Value

Type	Description
Vector2

Viewport

The pixels of the destination to draw into. An empty rectangle, the default, means the whole destination.

Declaration

public RectInt Viewport

Field Value

Type	Description
RectInt

Properties

Full

Gets the region of a picture that fills both textures completely.

Declaration

public static CRTImageRegion Full { get; }

Property Value

Type	Description
CRTImageRegion

HasSourceScale

Gets whether only part of the source texture holds the picture.

Declaration

public bool HasSourceScale { get; }

Property Value

Type	Description
bool

HasViewport

Gets whether only part of the destination is drawn into.

Declaration

public bool HasViewport { get; }

Property Value

Type	Description
bool

Methods

FromScaledTextures(Vector2, Vector2Int)

Creates the region of a picture drawn into the lower left part of textures that are larger than the picture, with the same layout in the source and the destination.

Declaration

public static CRTImageRegion FromScaledTextures(Vector2 scale, Vector2Int pictureSize)

Parameters

Type	Name	Description
Vector2	scale	The fraction of each texture the picture covers.
Vector2Int	pictureSize	The size of the picture in pixels.

Returns

Type	Description
CRTImageRegion	The region, or Full when the scale or the size has no area.

ResolveOutputSize(Vector2Int)

Returns the size of the picture drawn into the destination.

Declaration

public Vector2Int ResolveOutputSize(Vector2Int destinationSize)

Parameters

Type	Name	Description
Vector2Int	destinationSize	The size of the whole destination in pixels.

Returns

Type	Description
Vector2Int	The viewport's size when there is one; otherwise destinationSize.
