C Specification
To copy data from host memory to an image object, call:
// Provided by VK_VERSION_1_4
VkResult vkCopyMemoryToImage(
VkDevice device,
const VkCopyMemoryToImageInfo* pCopyMemoryToImageInfo);
or the equivalent command
// Provided by VK_EXT_host_image_copy
VkResult vkCopyMemoryToImageEXT(
VkDevice device,
const VkCopyMemoryToImageInfo* pCopyMemoryToImageInfo);
Parameters
-
device
is the device which ownspCopyMemoryToImageInfo->dstImage
. -
pCopyMemoryToImageInfo
is a pointer to a VkCopyMemoryToImageInfo structure describing the copy parameters.
Description
This command is functionally similar to vkCmdCopyBufferToImage2,
except it is executed on the host and reads from host memory instead of a
buffer.
The memory of pCopyMemoryToImageInfo->dstImage
is accessed by the host
as if coherent.
Note
|
Because queue submissions automatically make host memory visible to the device, there would not be a need for a memory barrier before using the results of this copy operation on the device. |
