C Specification

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

// Provided by VK_VERSION_1_0
void vkCmdCopyBufferToImage(
    VkCommandBuffer                             commandBuffer,
    VkBuffer                                    srcBuffer,
    VkImage                                     dstImage,
    VkImageLayout                               dstImageLayout,
    uint32_t                                    regionCount,
    const VkBufferImageCopy*                    pRegions);

Parameters

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

  • srcBuffer is the source buffer.

  • dstImage is the destination image.

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

  • regionCount is the number of regions to copy.

  • pRegions is a pointer to an array of VkBufferImageCopy structures specifying the regions to copy.

Description

Each source region specified by pRegions is copied from the source buffer to the destination region of the destination image according to the addressing calculations for each resource. If any of the specified regions in srcBuffer 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 be written as undefined values to the destination image.

Copy regions for the 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.
