vkCmdCopyImageToBuffer2(3)

Name

vkCmdCopyImageToBuffer2 - Copy image data into a buffer

C Specification

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

// Provided by VK_VERSION_1_3
void vkCmdCopyImageToBuffer2(
    VkCommandBuffer                             commandBuffer,
    const VkCopyImageToBufferInfo2*             pCopyImageToBufferInfo);
// Provided by VK_KHR_copy_commands2
// Equivalent to vkCmdCopyImageToBuffer2
void vkCmdCopyImageToBuffer2KHR(
    VkCommandBuffer                             commandBuffer,
    const VkCopyImageToBufferInfo2*             pCopyImageToBufferInfo);

Parameters

  • commandBuffer is the command buffer into which the command will be recorded.

  • pCopyImageToBufferInfo is a pointer to a VkCopyImageToBufferInfo2 structure describing the copy parameters.

Description

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

Valid Usage
  • VUID-vkCmdCopyImageToBuffer2-commandBuffer-01831
    If commandBuffer is an unprotected command buffer and protectedNoFault is not supported, srcImage must not be a protected image

  • VUID-vkCmdCopyImageToBuffer2-commandBuffer-01832
    If commandBuffer is an unprotected command buffer and protectedNoFault is not supported, dstBuffer must not be a protected buffer

  • VUID-vkCmdCopyImageToBuffer2-commandBuffer-01833
    If commandBuffer is a protected command buffer and protectedNoFault is not supported, dstBuffer must not be an unprotected buffer

  • VUID-vkCmdCopyImageToBuffer2-commandBuffer-07746
    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 pCopyImageToBufferInfo->pRegions must be a multiple of 4

  • VUID-vkCmdCopyImageToBuffer2-imageOffset-07747
    The imageOffset and imageExtent members of each element of pCopyImageToBufferInfo->pRegions must respect the image transfer granularity requirements of commandBuffer’s command pool’s queue family, as described in VkQueueFamilyProperties

  • VUID-vkCmdCopyImageToBuffer2-commandBuffer-10216
    If the queue family used to create the VkCommandPool which commandBuffer was allocated from does not support VK_QUEUE_GRAPHICS_BIT, and the maintenance10 feature is not enabled, for each element of pCopyImageToBufferInfo->pRegions, the aspectMask member of imageSubresource must not be VK_IMAGE_ASPECT_DEPTH_BIT or VK_IMAGE_ASPECT_STENCIL_BIT

  • VUID-vkCmdCopyImageToBuffer2-commandBuffer-11790
    If the queue family used to create the VkCommandPool which commandBuffer was allocated from does not support VK_QUEUE_GRAPHICS_BIT but does support VK_QUEUE_COMPUTE_BIT, and in any element of pCopyImageToBufferInfo->pRegions the aspectMask member of imageSubresource is VK_IMAGE_ASPECT_DEPTH_BIT, then the format features of srcImage must contain VK_FORMAT_FEATURE_2_DEPTH_COPY_ON_COMPUTE_QUEUE_BIT_KHR

  • VUID-vkCmdCopyImageToBuffer2-commandBuffer-11791
    If the queue family used to create the VkCommandPool which commandBuffer was allocated from does not support VK_QUEUE_GRAPHICS_BIT and VK_QUEUE_COMPUTE_BIT, but does support VK_QUEUE_TRANSFER_BIT, and in any element of pCopyImageToBufferInfo->pRegions the aspectMask member of imageSubresource is VK_IMAGE_ASPECT_DEPTH_BIT, then the format features of srcImage must contain VK_FORMAT_FEATURE_2_DEPTH_COPY_ON_TRANSFER_QUEUE_BIT_KHR

  • VUID-vkCmdCopyImageToBuffer2-commandBuffer-11792
    If the queue family used to create the VkCommandPool which commandBuffer was allocated from does not support VK_QUEUE_GRAPHICS_BIT but does support VK_QUEUE_COMPUTE_BIT, and in any element of pCopyImageToBufferInfo->pRegions the aspectMask member of imageSubresource is VK_IMAGE_ASPECT_STENCIL_BIT, then the format features of srcImage must contain VK_FORMAT_FEATURE_2_STENCIL_COPY_ON_COMPUTE_QUEUE_BIT_KHR

  • VUID-vkCmdCopyImageToBuffer2-commandBuffer-11793
    If the queue family used to create the VkCommandPool which commandBuffer was allocated from does not support VK_QUEUE_GRAPHICS_BIT and VK_QUEUE_COMPUTE_BIT, but does support VK_QUEUE_TRANSFER_BIT, and in any element of pCopyImageToBufferInfo->pRegions the aspectMask member of imageSubresource is VK_IMAGE_ASPECT_STENCIL_BIT, then the format features of srcImage must contain VK_FORMAT_FEATURE_2_STENCIL_COPY_ON_TRANSFER_QUEUE_BIT_KHR

Valid Usage (Implicit)
  • VUID-vkCmdCopyImageToBuffer2-commandBuffer-parameter
    commandBuffer must be a valid VkCommandBuffer handle

  • VUID-vkCmdCopyImageToBuffer2-pCopyImageToBufferInfo-parameter
    pCopyImageToBufferInfo must be a valid pointer to a valid VkCopyImageToBufferInfo2 structure

  • VUID-vkCmdCopyImageToBuffer2-commandBuffer-recording
    commandBuffer must be in the recording state

  • VUID-vkCmdCopyImageToBuffer2-commandBuffer-cmdpool
    The VkCommandPool that commandBuffer was allocated from must support VK_QUEUE_COMPUTE_BIT, VK_QUEUE_GRAPHICS_BIT, or VK_QUEUE_TRANSFER_BIT operations

  • VUID-vkCmdCopyImageToBuffer2-renderpass
    This command must only be called outside of a render pass instance

  • VUID-vkCmdCopyImageToBuffer2-suspended
    This command must not be called between suspended render pass instances

  • VUID-vkCmdCopyImageToBuffer2-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
