VkHostImageLayoutTransitionInfo

The VkHostImageLayoutTransitionInfo structure is defined as:

typedef struct VkHostImageLayoutTransitionInfo {
    VkStructureType sType;
    const void* pNext;
    VkImage image;
    VkImageLayout oldLayout;
    VkImageLayout newLayout;
    VkImageSubresourceRange subresourceRange;
} VkHostImageLayoutTransitionInfo;

or the equivalent

typedef VkHostImageLayoutTransitionInfo VkHostImageLayoutTransitionInfoEXT;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• image is a handle to the image affected by this layout transition.
• oldLayout is the old layout in an image layout transition.
• newLayout is the new layout in an image layout transition.
• subresourceRange describes the image subresource range within image that is affected by this layout transition.

vkTransitionImageLayout does not check whether the device memory associated with an image is currently in use before performing the layout transition. The application must guarantee that any previously submitted command that reads from or writes to this subresource has completed before the host performs the layout transition. The memory of image is accessed by the host as if coherent.
