# VkCommandBufferInheritanceRenderPassTransformInfoQCOM(3) Manual Page

## Name

VkCommandBufferInheritanceRenderPassTransformInfoQCOM - Structure describing transformed render pass parameters command buffer

Loading… please wait.

## C Specification

To begin recording a secondary command buffer compatible with execution inside a render pass using render pass transform, add the VkCommandBufferInheritanceRenderPassTransformInfoQCOM to the `pNext` chain of VkCommandBufferInheritanceInfo structure passed to the vkBeginCommandBuffer command specifying the parameters for transformed rasterization.

The `VkCommandBufferInheritanceRenderPassTransformInfoQCOM` structure is defined as:

    // Provided by VK_QCOM_render_pass_transform
    typedef struct VkCommandBufferInheritanceRenderPassTransformInfoQCOM {
        VkStructureType                  sType;
        void*                            pNext;
        VkSurfaceTransformFlagBitsKHR    transform;
        VkRect2D                         renderArea;
    } VkCommandBufferInheritanceRenderPassTransformInfoQCOM;

## 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 the render pass.

- `renderArea` is the render area that is affected by the command buffer.

## Description

When the secondary is recorded to execute within a render pass instance using vkCmdExecuteCommands, the render pass transform parameters of the secondary command buffer must be consistent with the render pass transform parameters specified for the render pass instance. In particular, the `transform` and `renderArea` for command buffer must be identical to the `transform` and `renderArea` of the render pass instance.

Valid Usage

- VUID-VkCommandBufferInheritanceRenderPassTransformInfoQCOM-transform-02864
  `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`

Valid Usage (Implicit)

- VUID-VkCommandBufferInheritanceRenderPassTransformInfoQCOM-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_COMMAND_BUFFER_INHERITANCE_RENDER_PASS_TRANSFORM_INFO_QCOM`
