# VkHostImageCopyFlagBitsEXT(3) Manual Page

## Name

VkHostImageCopyFlagBitsEXT - Bitmask specifying additional copy parameters

Loading… please wait.

## C Specification

Bits which can be set in VkCopyMemoryToImageInfoEXT::`flags`, VkCopyImageToMemoryInfoEXT::`flags`, and VkCopyImageToImageInfoEXT::`flags`, specifying additional copy parameters are:

    // Provided by VK_EXT_host_image_copy
    typedef enum VkHostImageCopyFlagBitsEXT {
        VK_HOST_IMAGE_COPY_MEMCPY_EXT = 0x00000001,
    } VkHostImageCopyFlagBitsEXT;

## Description

- `VK_HOST_IMAGE_COPY_MEMCPY_EXT` specifies that no memory layout swizzling is to be applied during data copy. For copies between memory and images, this flag indicates that image data in host memory is swizzled in exactly the same way as the image data on the device. Using this flag indicates that the implementations may use a simple memory copy to transfer the data between the host memory and the device memory. The format of the swizzled data in host memory is platform dependent and is not defined in this specification.
