VkCopyImageToMemoryInfoEXT

Structure specifying parameters of an image to host memory copy command

The VkCopyImageToMemoryInfoEXT structure is defined as:

typedef struct VkCopyImageToMemoryInfoEXT {
    VkStructureType sType;
    const void* pNext;
    VkHostImageCopyFlagsEXT flags;
    VkImage srcImage;
    VkImageLayout srcImageLayout;
    uint32_t regionCount;
    const VkImageToMemoryCopyEXT* pRegions;
} VkCopyImageToMemoryInfoEXT;
  • sType is a VkStructureType value identifying this structure.
  • pNext is NULL or a pointer to a structure extending this structure.
  • flags is a bitmask of VkHostImageCopyFlagBitsEXT values describing additional copy parameters.
  • srcImage is the source image.
  • srcImageLayout is the layout of the source image subresources for the copy.
  • regionCount is the number of regions to copy.
  • pRegions is a pointer to an array of VkImageToMemoryCopyEXT structures specifying the regions to copy.

vkCopyImageToMemoryEXT does not check whether the device memory associated with srcImage is currently in use before performing the copy. The application must guarantee that any previously submitted command that writes to the copy regions has completed before the host performs the copy.

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.
