Members
-
sType
is a VkStructureType value identifying this structure. -
pNext
isNULL
or a pointer to a structure extending this structure -
memoryTypeBits
is a bitmask containing one bit set for every memory type which the buffer collection can be imported as buffer collection -
bufferCount
is the number of buffers in the collection -
createInfoIndex
as described in Sysmem chosen create infos -
sysmemPixelFormat
is the SysmemPixelFormatType
as defined infuchsia.sysmem/image_formats.fidl
-
formatFeatures
is a bitmask of VkFormatFeatureFlagBits shared by the buffer collection -
sysmemColorSpaceIndex
is a VkSysmemColorSpaceFUCHSIA struct specifying the color space -
samplerYcbcrConversionComponents
is a VkComponentMapping struct specifying the component mapping -
suggestedYcbcrModel
is a VkSamplerYcbcrModelConversion value specifying the suggested Y′CBCR model -
suggestedYcbcrRange
is a VkSamplerYcbcrRange value specifying the suggested Y′CBCR range -
suggestedXChromaOffset
is a VkChromaLocation value specifying the suggested X chroma offset -
suggestedYChromaOffset
is a VkChromaLocation value specifying the suggested Y chroma offset
Description
sysmemColorSpace
is only set for image-based buffer collections where
the constraints were specified using VkImageConstraintsInfoFUCHSIA in
a call to vkSetBufferCollectionImageConstraintsFUCHSIA.
For image-based buffer collections, createInfoIndex
will identify both
the VkImageConstraintsInfoFUCHSIA::pImageCreateInfos
element and
the VkImageConstraintsInfoFUCHSIA::pFormatConstraints
element
chosen by Sysmem when vkSetBufferCollectionImageConstraintsFUCHSIA was
called.
The value of sysmemColorSpaceIndex
will be an index to one of the
color spaces provided in the
VkImageFormatConstraintsInfoFUCHSIA::pColorSpaces
array.
The implementation must have formatFeatures
with all bits set that
were set in
VkImageFormatConstraintsInfoFUCHSIA::requiredFormatFeatures
, by
the call to vkSetBufferCollectionImageConstraintsFUCHSIA, at
createInfoIndex
(other bits could be set as well).
