If presentation fails because of a mismatch in the surface and presented
image sizes, a ename:VK_ERROR_OUT_OF_DATE_KHR error will be returned.
Before an application can: present an image, the image's layout must: be
transitioned to the ename:VK_IMAGE_LAYOUT_PRESENT_SRC_KHR
ifdef::VK_KHR_shared_presentable_image[]
layout, or for a shared presentable image the
ename:VK_IMAGE_LAYOUT_SHARED_PRESENT_KHR
endif::VK_KHR_shared_presentable_image[]
layout.
.Note
[NOTE]
====
When transitioning the image to
ifdef::VK_KHR_shared_presentable_image[]
ename:VK_IMAGE_LAYOUT_SHARED_PRESENT_KHR or
endif::VK_KHR_shared_presentable_image[]
ename:VK_IMAGE_LAYOUT_PRESENT_SRC_KHR, there is no need to delay subsequent
processing, or perform any visibility operations (as flink:vkQueuePresentKHR
performs automatic visibility operations).
To achieve this, the pname:dstAccessMask member of the
slink:VkImageMemoryBarrier should: be set to `0`, and the pname:dstStageMask
parameter should: be set to ename:VK_PIPELINE_STAGE_BOTTOM_OF_PIPE_BIT.
