C Specification

To copy data between image objects, call:

// Provided by VK_VERSION_1_0
void vkCmdCopyImage(
    VkCommandBuffer                             commandBuffer,
    VkImage                                     srcImage,
    VkImageLayout                               srcImageLayout,
    VkImage                                     dstImage,
    VkImageLayout                               dstImageLayout,
    uint32_t                                    regionCount,
    const VkImageCopy*                          pRegions);

Parameters

commandBuffer is the command buffer into which the command will be recorded.
srcImage is the source image.
srcImageLayout is the current layout of the source image subresource.
dstImage is the destination image.
dstImageLayout is the current layout of the destination image subresource.
regionCount is the number of regions to copy.
pRegions is a pointer to an array of VkImageCopy structures specifying the regions to copy.

Description

Each source region specified by pRegions is copied from the source image to the destination region of the destination image. If any of the specified regions in srcImage overlaps in memory with any of the specified regions in dstImage, values read from those overlapping regions are undefined. If any region accesses a depth aspect in dstImage and the VK_EXT_depth_range_unrestricted extension is not enabled, values copied from srcBuffer outside of the range [0,1] will be written as undefined values to the destination image.

Multi-planar images can only be copied on a per-plane basis, and the subresources used in each region when copying to or from such images must specify only one plane, though different regions can specify different planes. When copying planes of multi-planar images, the format considered is the compatible format for that plane, rather than the format of the multi-planar image.

If the format of the destination image has a different block extent than the source image (e.g. one is a compressed format), the offset and extent for each of the regions specified is scaled according to the block extents of each format to match in size. Copy regions for each image must be aligned to a multiple of the texel block extent in each dimension, except at the edges of the image, where region extents must match the edge of the image.

Image data can be copied between images with different image types. If one image is VK_IMAGE_TYPE_3D and the other image is VK_IMAGE_TYPE_2D with multiple layers, then each slice is copied to or from a different layer; depth slices in the 3D image correspond to layerCount layers in the 2D image, with an effective depth of 1 used for the 2D image. If the maintenance5 feature is enabled, all other combinations are allowed and function as if 1D images are 2D images with a height of 1. Otherwise, other combinations of image types are disallowed.
