## Name

VkImageViewHandleInfoNVX - Structure specifying the image view for handle queries

Loading... please wait.

## C Specification

The `VkImageViewHandleInfoNVX` structure is defined as:

    typedef struct VkImageViewHandleInfoNVX {
        VkStructureType     sType;
        const void*         pNext;
        VkImageView         imageView;
        VkDescriptorType    descriptorType;
        VkSampler           sampler;
    } VkImageViewHandleInfoNVX;

## Members

- `sType` is the type of this structure.

- `pNext` is `NULL` or a pointer to an extension-specific structure.

- `imageView` is the image view to query.

- `descriptorType` is the type of descriptor for which to query a handle.

- `sampler` is the sampler to combine with the image view when generating the handle.

## Description

Valid Usage

- `descriptorType` must be `VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE`, `VK_DESCRIPTOR_TYPE_STORAGE_IMAGE`, or `VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER`

- `sampler` must be a valid VkSampler if `descriptorType` is `VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER`

- If descriptorType is `VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE` or `VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER`, the image that `imageView` was created from must have been created with the `VK_IMAGE_USAGE_SAMPLED_BIT` usage bit set

- If descriptorType is `VK_DESCRIPTOR_TYPE_STORAGE_IMAGE`, the image that `imageView` was created from must have been created with the `VK_IMAGE_USAGE_STORAGE_BIT` usage bit set

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_IMAGE_VIEW_HANDLE_INFO_NVX`

- `pNext` must be `NULL`

- `imageView` must be a valid VkImageView handle

- `descriptorType` must be a valid VkDescriptorType value

- If `sampler` is not VK_NULL_HANDLE, `sampler` must be a valid VkSampler handle

- Both of `imageView`, and `sampler` that are valid handles of non-ignored parameters must have been created, allocated, or retrieved from the same VkDevice
