C Specification
Possible values of VkImageCompressionControlEXT::flags,
specifying compression controls for an image, are:
// Provided by VK_EXT_image_compression_control
typedef enum VkImageCompressionFlagBitsEXT {
VK_IMAGE_COMPRESSION_DEFAULT_EXT = 0,
VK_IMAGE_COMPRESSION_FIXED_RATE_DEFAULT_EXT = 0x00000001,
VK_IMAGE_COMPRESSION_FIXED_RATE_EXPLICIT_EXT = 0x00000002,
VK_IMAGE_COMPRESSION_DISABLED_EXT = 0x00000004,
} VkImageCompressionFlagBitsEXT;Description
-
VK_IMAGE_COMPRESSION_DEFAULT_EXT specifies that the default image compression setting is used. Implementations must not apply fixed-rate compression.
-
VK_IMAGE_COMPRESSION_FIXED_RATE_DEFAULT_EXT specifies that the implementation may choose any supported fixed-rate compression setting in an implementation-defined manner based on the properties of the image.
-
VK_IMAGE_COMPRESSION_FIXED_RATE_EXPLICIT_EXT specifies that fixed-rate compression may be used and that the allowed compression rates are specified by VkImageCompressionControlEXT::
pFixedRateFlags. -
VK_IMAGE_COMPRESSION_DISABLED_EXT specifies that all lossless and fixed-rate compression should be disabled.
If VkImageCompressionControlEXT::flags is
VK_IMAGE_COMPRESSION_FIXED_RATE_EXPLICIT_EXT, then the ith
member of the pFixedRateFlags array specifies the allowed compression
rates for the image’s ith plane.
