## C Specification

The supported shading rate image palette entries are defined by VkShadingRatePaletteEntryNV:

    // Provided by VK_NV_shading_rate_image
    typedef enum VkShadingRatePaletteEntryNV {
        VK_SHADING_RATE_PALETTE_ENTRY_NO_INVOCATIONS_NV = 0,
        VK_SHADING_RATE_PALETTE_ENTRY_16_INVOCATIONS_PER_PIXEL_NV = 1,
        VK_SHADING_RATE_PALETTE_ENTRY_8_INVOCATIONS_PER_PIXEL_NV = 2,
        VK_SHADING_RATE_PALETTE_ENTRY_4_INVOCATIONS_PER_PIXEL_NV = 3,
        VK_SHADING_RATE_PALETTE_ENTRY_2_INVOCATIONS_PER_PIXEL_NV = 4,
        VK_SHADING_RATE_PALETTE_ENTRY_1_INVOCATION_PER_PIXEL_NV = 5,
        VK_SHADING_RATE_PALETTE_ENTRY_1_INVOCATION_PER_2X1_PIXELS_NV = 6,
        VK_SHADING_RATE_PALETTE_ENTRY_1_INVOCATION_PER_1X2_PIXELS_NV = 7,
        VK_SHADING_RATE_PALETTE_ENTRY_1_INVOCATION_PER_2X2_PIXELS_NV = 8,
        VK_SHADING_RATE_PALETTE_ENTRY_1_INVOCATION_PER_4X2_PIXELS_NV = 9,
        VK_SHADING_RATE_PALETTE_ENTRY_1_INVOCATION_PER_2X4_PIXELS_NV = 10,
        VK_SHADING_RATE_PALETTE_ENTRY_1_INVOCATION_PER_4X4_PIXELS_NV = 11,
    } VkShadingRatePaletteEntryNV;

## Description

The following table indicates the width and height (in pixels) of each fragment generated using the indicated shading rate, as well as the maximum number of fragment shader invocations launched for each fragment. When processing regions of a primitive that have a shading rate of `VK_SHADING_RATE_PALETTE_ENTRY_NO_INVOCATIONS_NV`, no fragments will be generated in that region.

Shading Rate | Width | Height | Invocations
--- | --- | --- | ---
`VK_SHADING_RATE_PALETTE_ENTRY_NO_INVOCATIONS_NV` | 0 | 0 | 0
`VK_SHADING_RATE_PALETTE_ENTRY_16_INVOCATIONS_PER_PIXEL_NV` | 1 | 1 | 16
`VK_SHADING_RATE_PALETTE_ENTRY_8_INVOCATIONS_PER_PIXEL_NV` | 1 | 1 | 8
`VK_SHADING_RATE_PALETTE_ENTRY_4_INVOCATIONS_PER_PIXEL_NV` | 1 | 1 | 4
`VK_SHADING_RATE_PALETTE_ENTRY_2_INVOCATIONS_PER_PIXEL_NV` | 1 | 1 | 2
`VK_SHADING_RATE_PALETTE_ENTRY_1_INVOCATION_PER_PIXEL_NV` | 1 | 1 | 1
`VK_SHADING_RATE_PALETTE_ENTRY_1_INVOCATION_PER_2X1_PIXELS_NV` | 2 | 1 | 1
`VK_SHADING_RATE_PALETTE_ENTRY_1_INVOCATION_PER_1X2_PIXELS_NV` | 1 | 2 | 1
`VK_SHADING_RATE_PALETTE_ENTRY_1_INVOCATION_PER_2X2_PIXELS_NV` | 2 | 2 | 1
`VK_SHADING_RATE_PALETTE_ENTRY_1_INVOCATION_PER_4X2_PIXELS_NV` | 4 | 2 | 1
`VK_SHADING_RATE_PALETTE_ENTRY_1_INVOCATION_PER_2X4_PIXELS_NV` | 2 | 4 | 1
`VK_SHADING_RATE_PALETTE_ENTRY_1_INVOCATION_PER_4X4_PIXELS_NV` | 4 | 4 | 1
