public class VkCopyMemoryToImageInfo extends org.lwjgl.system.Struct<VkCopyMemoryToImageInfo> implements org.lwjgl.system.NativeResource
Structure specifying parameters of host memory to image copy command.
Description

vkCopyMemoryToImage does not check whether the device memory associated with dstImage is currently in use before performing the copy. The application must guarantee that any previously submitted command that reads from or 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.

Valid Usage
  • If dstImage is non-sparse then the image or the specified disjoint plane must be bound completely and contiguously to a single VkDeviceMemory object
  • The dstSubresource.mipLevel member of each element of pRegions must be less than the mipLevels specified in VkImageCreateInfo when dstImage was created
  • If dstSubresource.layerCount is not REMAINING_ARRAY_LAYERS, dstSubresource.baseArrayLayer + dstSubresource.layerCount of each element of pRegions must be less than or equal to the arrayLayers specified in VkImageCreateInfo when dstImage was created
  • dstImage must not have been created with flags containing IMAGE_CREATE_SUBSAMPLED_BIT_EXT
  • The image region specified by each element of pRegions must be contained within the specified dstSubresource of dstImage
  • For each element of pRegions, dstOffset.x and (extent.width + dstOffset.x) must both be greater than or equal to 0 and less than or equal to the width of the specified dstSubresource of dstImage
  • For each element of pRegions, dstOffset.y and (extent.height + dstOffset.y) must both be greater than or equal to 0 and less than or equal to the height of the specified dstSubresource of dstImage
  • For each element of pRegions, bufferRowLength must be a multiple of the texel block extent width of the VkFormat of dstImage
  • For each element of pRegions, bufferImageHeight must be a multiple of the texel block extent height of the VkFormat of dstImage
  • For each element of pRegions, bufferRowLength divided by the texel block extent width and then multiplied by the texel block size of dstImage must be less than or equal to 231-1
  • dstImageLayout must specify the current layout of the image subresources of dstImage specified in pRegions
  • dstImageLayout must be one of the image layouts returned in VkPhysicalDeviceHostImageCopyProperties::pCopyDstLayouts
  • If flags includes HOST_IMAGE_COPY_MEMCPY, for each region in pRegions, memoryRowLength and memoryImageHeight must both be 0
Valid Usage (Implicit)
  • sType must be STRUCTURE_TYPE_COPY_MEMORY_TO_IMAGE_INFO
  • pNext must be NULL
  • flags must be a valid combination of VkHostImageCopyFlagBits values
  • dstImage must be a valid VkImage handle
  • dstImageLayout must be a valid VkImageLayout value
  • pRegions must be a valid pointer to an array of regionCount valid VkMemoryToImageCopy structures
  • regionCount must be greater than 0
