VK_FORMAT_FEATURE_TRANSFER_[SRC|DST]_BIT_KHR is a flag value of the
VkFormatFeatureFlagBits enum that can only be hold and checked against
the linearTilingFeatures or optimalTilingFeatures members of the
VkFormatProperties struct but not the bufferFeatures member.
From the Vulkan® 1.0.51, with the VK_KHR_maintenance1 extension,
section 32.3.2 docs for 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."
...
Bits which can be set in the VkFormatProperties features
linearTilingFeatures, optimalTilingFeatures, and bufferFeatures
are:
typedef enum VkFormatFeatureFlagBits {
...
VK_FORMAT_FEATURE_TRANSFER_SRC_BIT_KHR = 0x00004000,
VK_FORMAT_FEATURE_TRANSFER_DST_BIT_KHR = 0x00008000,
...
} VkFormatFeatureFlagBits;
...
The following bits may be set in linearTilingFeatures and
optimalTilingFeatures, specifying that the features are supported
by images or image views created with the queried
vkGetPhysicalDeviceFormatProperties::format:
...
* VK_FORMAT_FEATURE_TRANSFER_SRC_BIT_KHR specifies that an image
can be used as a source image for copy commands.
* VK_FORMAT_FEATURE_TRANSFER_DST_BIT_KHR specifies that an image
can be used as a destination image for copy commands and clear
commands."
