# VkSampleCountFlagBits(3) Manual Page

## Name

VkSampleCountFlagBits - Bitmask specifying sample counts supported for an image used for storage operations

Loading… please wait.

## C Specification

Bits which may be set in the sample count limits returned by VkPhysicalDeviceLimits, as well as in other queries and structures representing image sample counts, are:

    // Provided by VK_VERSION_1_0
    typedef enum VkSampleCountFlagBits {
        VK_SAMPLE_COUNT_1_BIT = 0x00000001,
        VK_SAMPLE_COUNT_2_BIT = 0x00000002,
        VK_SAMPLE_COUNT_4_BIT = 0x00000004,
        VK_SAMPLE_COUNT_8_BIT = 0x00000008,
        VK_SAMPLE_COUNT_16_BIT = 0x00000010,
        VK_SAMPLE_COUNT_32_BIT = 0x00000020,
        VK_SAMPLE_COUNT_64_BIT = 0x00000040,
    } VkSampleCountFlagBits;

## Description

- `VK_SAMPLE_COUNT_1_BIT` specifies an image with one sample per pixel.

- `VK_SAMPLE_COUNT_2_BIT` specifies an image with 2 samples per pixel.

- `VK_SAMPLE_COUNT_4_BIT` specifies an image with 4 samples per pixel.

- `VK_SAMPLE_COUNT_8_BIT` specifies an image with 8 samples per pixel.

- `VK_SAMPLE_COUNT_16_BIT` specifies an image with 16 samples per pixel.

- `VK_SAMPLE_COUNT_32_BIT` specifies an image with 32 samples per pixel.

- `VK_SAMPLE_COUNT_64_BIT` specifies an image with 64 samples per pixel.
