Methods

AllocatesMemory(Camera, ImageComparisonSettings, Int32)

Render an image from the given camera and check if it allocated memory while doing so.

Declaration

public static void AllocatesMemory(Camera camera, ImageComparisonSettings settings = null, int gcAllocThreshold = 0)

Parameters

Type	Name	Description
Camera	camera	The camera to render from.
ImageComparisonSettings	settings
Int32	gcAllocThreshold

AreEqual(Texture2D, Camera, ImageComparisonSettings)

Render an image from the given camera and compare it to the reference image.

Declaration

public static void AreEqual(Texture2D expected, Camera camera, ImageComparisonSettings settings = null)

Parameters

Type	Name	Description
Texture2D	expected	The expected image that should be rendered by the camera.
Camera	camera	The camera to render from.
ImageComparisonSettings	settings	Optional settings that control how the image comparison is performed. Can be null, in which case the rendered image is required to be exactly identical to the reference.

AreEqual(Texture2D, IEnumerable<Camera>, ImageComparisonSettings)

Render an image from the given cameras and compare it to the reference image.

Declaration

public static void AreEqual(Texture2D expected, IEnumerable<Camera> cameras, ImageComparisonSettings settings = null)

Parameters

Type	Name	Description
Texture2D	expected	The expected image that should be rendered by the camera.
IEnumerable<Camera>	cameras	The cameras to render from.
ImageComparisonSettings	settings	Optional settings that control how the image comparison is performed. Can be null, in which case the rendered image is required to be exactly identical to the reference.

AreEqual(Texture2D, Texture2D, ImageComparisonSettings)

Compares an image to a 'reference' image to see if it looks correct.

Declaration

public static void AreEqual(Texture2D expected, Texture2D actual, ImageComparisonSettings settings = null)

Parameters

Type	Name	Description
Texture2D	expected	What the image is supposed to look like.
Texture2D	actual	What the image actually looks like.
ImageComparisonSettings	settings	Optional settings that control how the comparison is performed. Can be null, in which case the images are required to be exactly identical.

ResizeInto(Texture2D, Texture2D)

Resize a source texture to match the dimensions of the destination texture

Declaration

public static Texture2D ResizeInto(Texture2D source, Texture2D dest)

Parameters

Type	Name	Description
Texture2D	source
Texture2D	dest

Returns

Type	Description
Texture2D
