C Specification

If the pNext chain includes a VkImageViewASTCDecodeModeEXT structure, then that structure includes a parameter specifying the decode mode for image views using ASTC compressed formats.

The VkImageViewASTCDecodeModeEXT structure is defined as:

// Provided by VK_EXT_astc_decode_mode
typedef struct VkImageViewASTCDecodeModeEXT {
    VkStructureType    sType;
    const void*        pNext;
    VkFormat           decodeMode;
} VkImageViewASTCDecodeModeEXT;

Members

  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • decodeMode is the intermediate format used to decode ASTC compressed formats.

Description

Valid Usage

If format uses sRGB encoding then the decodeMode has no effect.

Valid Usage (Implicit)
