GRVkYcbcrConversionInfo Struct

Definition

Namespace:

SkiaSharp

Assembly:

SkiaSharp.dll

Describes the parameters for Vulkan YCbCr sampler conversion.

public struct GRVkYcbcrConversionInfo : IEquatable<SkiaSharp.GRVkYcbcrConversionInfo>

Inheritance

ValueType

GRVkYcbcrConversionInfo

Implements

IEquatable<GRVkYcbcrConversionInfo>

Examples

Creating a basic YCbCr conversion info for a Vulkan YUV420 image:

var conversionInfo = new GRVkYcbcrConversionInfo
{
    Format = 1000156003, // VK_FORMAT_G8_B8R8_2PLANE_420_UNORM
    ExternalFormat = 0,
    YcbcrModel = 1,      // VK_SAMPLER_YCBCR_MODEL_CONVERSION_YCBCR_709
    YcbcrRange = 0,      // VK_SAMPLER_YCBCR_RANGE_ITU_FULL
    ChromaFilter = 1,    // VK_FILTER_LINEAR
    XChromaOffset = 0,
    YChromaOffset = 0,
    ForceExplicitReconstruction = 0,
};

Remarks

`GRVkYcbcrConversionInfo` provides the Vulkan-specific parameters required to create a `VkSamplerYcbcrConversion` object. It is used when creating GPU-backed surfaces or images that use a YCbCr color model, such as Android hardware buffers with YUV formats.

The properties map directly to fields in `VkSamplerYcbcrConversionCreateInfo`.

Properties

Name	Description
ChromaFilter	Gets or sets the chroma filter used when reconstructing YCbCr chroma values.
Components	Gets or sets the component mapping for this YCbCr conversion.
ExternalFormat	Gets or sets the Vulkan external format for this YCbCr conversion.
ForceExplicitReconstruction	Gets or sets whether explicit chroma reconstruction is required.
Format	Gets or sets the Vulkan image format for this YCbCr conversion.
SamplerFilterMustMatchChromaFilter	Gets or sets whether the sampler filter must match the chroma reconstruction filter.
SupportsLinearFilter	Gets or sets whether linear filtering is supported for this YCbCr conversion.
XChromaOffset	Gets or sets the horizontal chroma sample location offset.
YcbcrModel	Gets or sets the YCbCr color model conversion.
YcbcrRange	Gets or sets the quantization range of the encoded YCbCr values.
YChromaOffset	Gets or sets the vertical chroma sample location offset.
