VkImageConstraintsInfoFUCHSIA
The VkImageConstraintsInfoFUCHSIA
structure is defined as:
typedef struct VkImageConstraintsInfoFUCHSIA {
VkStructureType sType;
const void* pNext;
uint32_t formatConstraintsCount;
const VkImageFormatConstraintsInfoFUCHSIA* pFormatConstraints;
VkBufferCollectionConstraintsInfoFUCHSIA bufferCollectionConstraints;
VkImageConstraintsInfoFlagsFUCHSIA flags;
} VkImageConstraintsInfoFUCHSIA;
sType
is a VkStructureType value identifying this structure.pNext
isNULL
or a pointer to a structure extending this structure.formatConstraintsCount
is the number of elements inpFormatConstraints
.pFormatConstraints
is a pointer to an array of VkImageFormatConstraintsInfoFUCHSIA structures of sizeformatConstraintsCount
that is used to further constrain buffer collection format selection for image-based buffer collections.bufferCollectionConstraints
is a VkBufferCollectionConstraintsInfoFUCHSIA structure used to supply parameters for the negotiation and allocation for buffer-based buffer collections.flags
is a VkImageConstraintsInfoFlagBitsFUCHSIA value specifying hints about the type of memory Sysmem should allocate for the buffer collection.
