Syntax

public class ImageComparisonSettings

Fields

ActiveImageTests

Determines which tests are active when comparing the images.

Declaration

[Tooltip("Determines which tests are active when comparing the images.")]
public ImageComparisonSettings.ImageTests ActiveImageTests

Field Value

Type	Description
ImageComparisonSettings.ImageTests

ActivePixelTests

Determines which tests are active when determining whether an individual pixel is correct or not. An incorrect pixel will increase the counter associated with the IncorrectPixelsCount image test. This is only relevant when ActiveImageTests has the IncorrectPixelsCount flag set.

Declaration

[Tooltip("Determines which tests affect the counter used by the IncorrectPixelsCount image test.")]
public ImageComparisonSettings.PixelTests ActivePixelTests

Field Value

Type	Description
ImageComparisonSettings.PixelTests

AverageCorrectnessThreshold

The maximum permitted average error value across the entire image. If the average per-pixel difference across the image is above this value, the images are considered not to be equal.

Declaration

[Tooltip("The maximum permitted average error value across the entire image.")]
public float AverageCorrectnessThreshold

Field Value

Type	Description
float

ImageResolution

If using Back Buffer, reference images need to be 16:9 aspect ratio

Declaration

[Tooltip("If using Back Buffer, reference images need to be in one of these resolutions.")]
public ImageComparisonSettings.Resolution ImageResolution

Field Value

Type	Description
ImageComparisonSettings.Resolution

IncorrectPixelsThreshold

The maximum ratio of pixels allowed to be incorrect across the image. A pixel is incorrect if it exceeds the specified per-pixel thresholds.

Declaration

[Tooltip("The maximum ratio of pixels allowed to be incorrect across the image.")]
public float IncorrectPixelsThreshold

Field Value

Type	Description
float

PerPixelAlphaThreshold

The permitted difference between the alpha component of individual pixels of the images.

Declaration

[Tooltip("The permitted difference between the alpha component of individual pixels of the images.")]
public float PerPixelAlphaThreshold

Field Value

Type	Description
float

PerPixelCorrectnessThreshold

The permitted perceptual difference between individual pixels of the images.

The deltaE for each pixel of the image is compared and any differences below this threshold are ignored.

Declaration

[Tooltip("The permitted perceptual difference between individual pixels of the images.")]
public float PerPixelCorrectnessThreshold

Field Value

Type	Description
float

PerPixelGammaThreshold

The permitted difference between the RGB components (in gamma) of individual pixels of the images.

Declaration

[Tooltip("The permitted difference between the RGB components (in gamma) of individual pixels of the images.")]
public float PerPixelGammaThreshold

Field Value

Type	Description
float

RMSEThreshold

The maximum permitted root mean squared error value across the entire image. If the root mean squared per-pixel error across the image is above this value, the images are considered not to be equal.

Declaration

[Tooltip("The maximum permitted root mean squared error value across the entire image.")]
public float RMSEThreshold

Field Value

Type	Description
float

TargetHeight

The height to use for the rendered image. If a reference image already exists for this test and has a different size the test will fail.

Declaration

[Tooltip("The height to use for the rendered image.")]
public int TargetHeight

Field Value

Type	Description
int

TargetMSAASamples

The sample count needed for the test scene to be compared

Declaration

public int TargetMSAASamples

Field Value

Type	Description
int

TargetWidth

The width to use for the rendered image. If a reference image already exists for this test and has a different size the test will fail.

Declaration

[Tooltip("The width to use for the rendered image.")]
public int TargetWidth

Field Value

Type	Description
int

UseBackBuffer

Use back buffer capture

Declaration

[Tooltip("If enabled, tests will use the back buffer, as opposed to a render texture.")]
public bool UseBackBuffer

Field Value

Type	Description
bool

UseHDR

Use HDR rendering

Declaration

[Tooltip("If enabled, render textures will be created with DefaultHDR format.")]
public bool UseHDR

Field Value

Type	Description
bool
