C Specification

For both vkCmdCopyBufferToImage and vkCmdCopyImageToBuffer, each element of pRegions is a structure defined as:

// Provided by VK_VERSION_1_0
typedef struct VkBufferImageCopy {
    VkDeviceSize                bufferOffset;
    uint32_t                    bufferRowLength;
    uint32_t                    bufferImageHeight;
    VkImageSubresourceLayers    imageSubresource;
    VkOffset3D                  imageOffset;
    VkExtent3D                  imageExtent;
} VkBufferImageCopy;


  • bufferOffset is the offset in bytes from the start of the buffer object where the image data is copied from or to.

  • bufferRowLength and bufferImageHeight specify in texels a subregion of a larger two- or three-dimensional image in buffer memory, and control the addressing calculations. If either of these values is zero, that aspect of the buffer memory is considered to be tightly packed according to the imageExtent.

  • imageSubresource is a VkImageSubresourceLayers used to specify the specific image subresources of the image used for the source or destination image data.

  • imageOffset selects the initial x, y, z offsets in texels of the sub-region of the source or destination image data.

  • imageExtent is the size in texels of the image to copy in width, height and depth.


Valid Usage
  • VUID-VkBufferImageCopy-bufferRowLength-09101
    bufferRowLength must be 0, or greater than or equal to the width member of imageExtent

  • VUID-VkBufferImageCopy-bufferImageHeight-09102
    bufferImageHeight must be 0, or greater than or equal to the height member of imageExtent

  • VUID-VkBufferImageCopy-aspectMask-09103
    The aspectMask member of imageSubresource must only have a single bit set

  • VUID-VkBufferImageCopy-imageExtent-06659
    imageExtent.width must not be 0

  • VUID-VkBufferImageCopy-imageExtent-06660
    imageExtent.height must not be 0

  • VUID-VkBufferImageCopy-imageExtent-06661
    imageExtent.depth must not be 0
