# VkSamplerCreateFlagBits(3) Manual Page

## Name

VkSamplerCreateFlagBits - Bitmask specifying additional parameters of sampler

Loading… please wait.

## C Specification

Bits which can be set in VkSamplerCreateInfo::`flags`, specifying additional parameters of a sampler, are:

    // Provided by VK_VERSION_1_0
    typedef enum VkSamplerCreateFlagBits {
      // Provided by VK_EXT_fragment_density_map
        VK_SAMPLER_CREATE_SUBSAMPLED_BIT_EXT = 0x00000001,
      // Provided by VK_EXT_fragment_density_map
        VK_SAMPLER_CREATE_SUBSAMPLED_COARSE_RECONSTRUCTION_BIT_EXT = 0x00000002,
      // Provided by VK_EXT_descriptor_buffer
        VK_SAMPLER_CREATE_DESCRIPTOR_BUFFER_CAPTURE_REPLAY_BIT_EXT = 0x00000008,
      // Provided by VK_EXT_non_seamless_cube_map
        VK_SAMPLER_CREATE_NON_SEAMLESS_CUBE_MAP_BIT_EXT = 0x00000004,
      // Provided by VK_QCOM_image_processing
        VK_SAMPLER_CREATE_IMAGE_PROCESSING_BIT_QCOM = 0x00000010,
    } VkSamplerCreateFlagBits;

## Description

- `VK_SAMPLER_CREATE_SUBSAMPLED_BIT_EXT` specifies that the sampler will read from an image created with `flags` containing `VK_IMAGE_CREATE_SUBSAMPLED_BIT_EXT`.

- `VK_SAMPLER_CREATE_SUBSAMPLED_COARSE_RECONSTRUCTION_BIT_EXT` specifies that the implementation may use approximations when reconstructing a full color value for texture access from a subsampled image.

- `VK_SAMPLER_CREATE_NON_SEAMLESS_CUBE_MAP_BIT_EXT` specifies that cube map edge handling is not performed.

- `VK_SAMPLER_CREATE_IMAGE_PROCESSING_BIT_QCOM` specifies that the sampler will read from images using only `OpImageWeightedSampleQCOM`, `OpImageBoxFilterQCOM`, `OpImageBlockMatchGatherSSDQCOM`, `OpImageBlockMatchGatherSADQCOM`, `OpImageBlockMatchWindowSSDQCOM`, `OpImageBlockMatchWindowSADQCOM`, `OpImageBlockMatchSSDQCOM`, or `OpImageBlockMatchSADQCOM`.

Note | The approximations used when `VK_SAMPLER_CREATE_SUBSAMPLED_COARSE_RECONSTRUCTION_BIT_EXT` is specified are implementation defined. Some implementations may interpolate between fragment density levels in a subsampled image. In that case, this bit may be used to decide whether the interpolation factors are calculated per fragment or at a coarser granularity.

- `VK_SAMPLER_CREATE_DESCRIPTOR_BUFFER_CAPTURE_REPLAY_BIT_EXT` specifies that the sampler can be used with descriptor buffers when capturing and replaying (e.g. for trace capture and replay), see VkOpaqueCaptureDescriptorDataCreateInfoEXT for more detail.
