C Specification

The VkPhysicalDeviceASTCDecodeFeaturesEXT structure is defined as:

typedef struct VkPhysicalDeviceASTCDecodeFeaturesEXT {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           decodeModeSharedExponent;
} VkPhysicalDeviceASTCDecodeFeaturesEXT;


The members of the VkPhysicalDeviceASTCDecodeFeaturesEXT structure describe the following features:


  • decodeModeSharedExponent indicates whether the implementation supports decoding ASTC compressed formats to VK_FORMAT_E5B9G9R9_UFLOAT_PACK32 internal precision.

If the VkPhysicalDeviceASTCDecodeFeaturesEXT structure is included in the pNext chain of VkPhysicalDeviceFeatures2, it is filled with values indicating whether each feature is supported. VkPhysicalDeviceASTCDecodeFeaturesEXT can also be included in the pNext chain of vkCreateDevice to enable features.
