# vkCmdCopyBufferToImage2(3) Manual Page

## Name

vkCmdCopyBufferToImage2 - Copy data from a buffer into an image

Loading… please wait.

## C Specification

To copy data from a buffer object to an image object, call:

    // Provided by VK_VERSION_1_3
    void vkCmdCopyBufferToImage2(
        VkCommandBuffer                             commandBuffer,
        const VkCopyBufferToImageInfo2*             pCopyBufferToImageInfo);

or the equivalent command

    // Provided by VK_KHR_copy_commands2
    void vkCmdCopyBufferToImage2KHR(
        VkCommandBuffer                             commandBuffer,
        const VkCopyBufferToImageInfo2*             pCopyBufferToImageInfo);

## Parameters

- `commandBuffer` is the command buffer into which the command will be recorded.

- `pCopyBufferToImageInfo` is a pointer to a VkCopyBufferToImageInfo2 structure describing the copy parameters.

## Description

This command is functionally identical to vkCmdCopyBufferToImage, but includes extensible sub-structures that include `sType` and `pNext` parameters, allowing them to be more easily extended.

Valid Usage

- VUID-vkCmdCopyBufferToImage2-commandBuffer-01828
  If `commandBuffer` is an unprotected command buffer and `protectedNoFault` is not supported, `srcBuffer` must not be a protected buffer

- VUID-vkCmdCopyBufferToImage2-commandBuffer-01829
  If `commandBuffer` is an unprotected command buffer and `protectedNoFault` is not supported, `dstImage` must not be a protected image

- VUID-vkCmdCopyBufferToImage2-commandBuffer-01830
  If `commandBuffer` is a protected command buffer and `protectedNoFault` is not supported, `dstImage` must not be an unprotected image

- VUID-vkCmdCopyBufferToImage2-commandBuffer-07737
  If the queue family used to create the VkCommandPool which `commandBuffer` was allocated from does not support `VK_QUEUE_GRAPHICS_BIT` or `VK_QUEUE_COMPUTE_BIT`, the `bufferOffset` member of any element of `pCopyBufferToImageInfo->pRegions` must be a multiple of `4`

- VUID-vkCmdCopyBufferToImage2-imageOffset-07738
  The `imageOffset` and `imageExtent` members of each element of `pCopyBufferToImageInfo->pRegions` must respect the image transfer granularity requirements of `commandBuffer`’s command pool’s queue family, as described in VkQueueFamilyProperties

- VUID-vkCmdCopyBufferToImage2-commandBuffer-07739
  If the queue family used to create the VkCommandPool which `commandBuffer` was allocated from does not support `VK_QUEUE_GRAPHICS_BIT`, for each element of `pCopyBufferToImageInfo->pRegions`, the `aspectMask` member of `imageSubresource` must not be `VK_IMAGE_ASPECT_DEPTH_BIT` or `VK_IMAGE_ASPECT_STENCIL_BIT`

Valid Usage (Implicit)

- VUID-vkCmdCopyBufferToImage2-commandBuffer-parameter
  `commandBuffer` must be a valid VkCommandBuffer handle

- VUID-vkCmdCopyBufferToImage2-pCopyBufferToImageInfo-parameter
  `pCopyBufferToImageInfo` must be a valid pointer to a valid VkCopyBufferToImageInfo2 structure

- VUID-vkCmdCopyBufferToImage2-commandBuffer-recording
  `commandBuffer` must be in the recording state

- VUID-vkCmdCopyBufferToImage2-commandBuffer-cmdpool
  The `VkCommandPool` that `commandBuffer` was allocated from must support transfer, graphics, or compute operations

- VUID-vkCmdCopyBufferToImage2-renderpass
  This command must only be called outside of a render pass instance

- VUID-vkCmdCopyBufferToImage2-videocoding
  This command must only be called outside of a video coding scope

Host Synchronization

- Host access to `commandBuffer` must be externally synchronized

- Host access to the `VkCommandPool` that `commandBuffer` was allocated from must be externally synchronized

Command Properties

Command Buffer Levels | Render Pass Scope | Video Coding Scope | Supported Queue Types | Command Type
--- | --- | --- | --- | ---
Primary Secondary | Outside | Outside | Transfer Graphics Compute | Action
