# VkRenderPassTransformBeginInfoQCOM(3) Manual Page

## Name

VkRenderPassTransformBeginInfoQCOM - Structure describing transform parameters of a render pass instance

Loading… please wait.

## C Specification

To begin a render pass instance with render pass transform enabled, add the VkRenderPassTransformBeginInfoQCOM to the `pNext` chain of VkRenderPassBeginInfo structure passed to the vkCmdBeginRenderPass command specifying the render pass transform.

The `VkRenderPassTransformBeginInfoQCOM` structure is defined as:

    // Provided by VK_QCOM_render_pass_transform
    typedef struct VkRenderPassTransformBeginInfoQCOM {
        VkStructureType                  sType;
        void*                            pNext;
        VkSurfaceTransformFlagBitsKHR    transform;
    } VkRenderPassTransformBeginInfoQCOM;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `transform` is a VkSurfaceTransformFlagBitsKHR value describing the transform to be applied to rasterization.

## Description

Valid Usage

- VUID-VkRenderPassTransformBeginInfoQCOM-transform-02871
  `transform` must be `VK_SURFACE_TRANSFORM_IDENTITY_BIT_KHR`, `VK_SURFACE_TRANSFORM_ROTATE_90_BIT_KHR`, `VK_SURFACE_TRANSFORM_ROTATE_180_BIT_KHR`, or `VK_SURFACE_TRANSFORM_ROTATE_270_BIT_KHR`

- VUID-VkRenderPassTransformBeginInfoQCOM-flags-02872
  The `renderpass` must have been created with VkRenderPassCreateInfo::`flags` containing `VK_RENDER_PASS_CREATE_TRANSFORM_BIT_QCOM`

Valid Usage (Implicit)

- VUID-VkRenderPassTransformBeginInfoQCOM-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_RENDER_PASS_TRANSFORM_BEGIN_INFO_QCOM`
