VkFormatProperties

Structure specifying image format properties

The VkFormatProperties structure is defined as:

typedef struct VkFormatProperties {
    VkFormatFeatureFlags linearTilingFeatures;
    VkFormatFeatureFlags optimalTilingFeatures;
    VkFormatFeatureFlags bufferFeatures;
} VkFormatProperties;
  • linearTilingFeatures is a bitmask of VkFormatFeatureFlagBits specifying features supported by images created with a tiling parameter of VK_IMAGE_TILING_LINEAR.
  • optimalTilingFeatures is a bitmask of VkFormatFeatureFlagBits specifying features supported by images created with a tiling parameter of VK_IMAGE_TILING_OPTIMAL.
  • bufferFeatures is a bitmask of VkFormatFeatureFlagBits specifying features supported by buffers.

If no format feature flags are supported, the format itself is not supported, and images of that format cannot be created.

If format is block-compressed, requires sampler Y′CBCR conversion, or is a depth/stencil format then bufferFeatures must not support any features for the format.

If format is not a multi-plane format then linearTilingFeatures and optimalTilingFeatures must not contain VK_FORMAT_FEATURE_DISJOINT_BIT.
