# VkRenderPassTransformBeginInfoQCOM(3) Manual Page

## Name

VkRenderPassTransformBeginInfoQCOM - Structure describing transform parameters of a render pass instance

## C Specification

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

The `VkRenderPassTransformBeginInfoQCOM` structure is defined as:

    typedef struct VkRenderPassTransformBeginInfoQCOM {
        VkStructureType                  sType;
        void*                            pNext;
        VkSurfaceTransformFlagBitsKHR    transform;
    } VkRenderPassTransformBeginInfoQCOM;

## Members

- `sType` is the type of this structure.

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

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

## Description

Valid Usage

- `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.

- The renderpass must have been created with VkRenderPassCreateInfo::`flags` containing VK_RENDER_PASS_CREATE_TRANSFORM_BIT_QCOM.

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_RENDER_PASS_TRANSFORM_BEGIN_INFO_QCOM`
