# vkGetDeviceCombinedImageSamplerIndexNVX(3) Manual Page

## Name

vkGetDeviceCombinedImageSamplerIndexNVX - Get the handle for an image view and sampler index

Loading… please wait.

## C Specification

To get the handle for a combined image sampler, call:

    // Provided by VK_NVX_image_view_handle
    uint64_t vkGetDeviceCombinedImageSamplerIndexNVX(
        VkDevice                                    device,
        uint64_t                                    imageViewIndex,
        uint64_t                                    samplerIndex);

## Parameters

- `device` is the logical device that will use the result handle.

- `imageViewIndex` is the index within the resource heap.

- `samplerIndex` is the index within the sampler heap.

## Description

Shaders take `imageViewIndex` and `samplerIndex`, and multiply it by VkPhysicalDeviceDescriptorHeapPropertiesEXT::`imageDescriptorSize` and VkPhysicalDeviceDescriptorHeapPropertiesEXT::`samplerDescriptorSize` respectively to obtain the descriptor offset in bytes.

Valid Usage (Implicit)

- VUID-vkGetDeviceCombinedImageSamplerIndexNVX-device-parameter
  `device` must be a valid VkDevice handle
