C Specification

To copy data from a memory region to an image object by specifying copy parameters in a buffer, call:

// Provided by VK_NV_copy_memory_indirect
void vkCmdCopyMemoryToImageIndirectNV(
    VkCommandBuffer                             commandBuffer,
    VkDeviceAddress                             copyBufferAddress,
    uint32_t                                    copyCount,
    uint32_t                                    stride,
    VkImage                                     dstImage,
    VkImageLayout                               dstImageLayout,
    const VkImageSubresourceLayers*             pImageSubresources);


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

  • copyBufferAddress is the buffer address specifying the copy parameters. This buffer is laid out in memory as an array of VkCopyMemoryToImageIndirectCommandNV structures.

  • copyCount is the number of copies to execute, and can be zero.

  • stride is the byte stride between successive sets of copy parameters.

  • dstImage is the destination image.

  • dstImageLayout is the layout of the destination image subresources for the copy.

  • pImageSubresources is a pointer to an array of size copyCount of VkImageSubresourceLayers used to specify the specific image subresource of the destination image data for that copy.


Each region in copyBufferAddress is copied from the source memory region to an image region in the destination image. If the destination image is of type VK_IMAGE_TYPE_3D, the starting slice and number of slices to copy are specified in pImageSubresources->baseArrayLayer and pImageSubresources->layerCount respectively. The copy must be performed on a queue that supports indirect copy operations, see VkPhysicalDeviceCopyMemoryIndirectPropertiesNV.

  • VUID-vkCmdCopyMemoryToImageIndirectNV-imageOffset-07672
    The imageOffset and imageExtent members of each region must respect the image transfer granularity requirements of commandBuffer’s command pool’s queue family, as described in VkQueueFamilyProperties

  • VUID-vkCmdCopyMemoryToImageIndirectNV-dstImage-07673
    dstImage must not have been created with flags containing VK_IMAGE_CREATE_SUBSAMPLED_BIT_EXT

  • VUID-vkCmdCopyMemoryToImageIndirectNV-commandBuffer-07674
    If the queue family used to create the VkCommandPool which commandBuffer was allocated from does not support VK_QUEUE_GRAPHICS_BIT, for each region, the aspectMask member of pImageSubresources must not be VK_IMAGE_ASPECT_DEPTH_BIT or VK_IMAGE_ASPECT_STENCIL_BIT

  • VUID-vkCmdCopyMemoryToImageIndirectNV-imageOffset-07675
    For each region in copyBufferAddress, imageOffset.y and (imageExtent.height + imageOffset.y) must both be greater than or equal to 0 and less than or equal to the height of the specified subresource

  • VUID-vkCmdCopyMemoryToImageIndirectNV-offset-07676
    offset must be 4 byte aligned

    pImageSubresources must be a valid pointer to an array of copyCount valid VkImageSubresourceLayers structures

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

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

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

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