C Specification
Bits which may be set in the
VkSurfacePresentScalingCapabilitiesKHR::supportedPresentGravityX
or supportedPresentGravityY fields, specifying the gravity of
presented pixels supported by the surface, are:
// Provided by VK_KHR_surface_maintenance1
typedef enum VkPresentGravityFlagBitsKHR {
VK_PRESENT_GRAVITY_MIN_BIT_KHR = 0x00000001,
VK_PRESENT_GRAVITY_MAX_BIT_KHR = 0x00000002,
VK_PRESENT_GRAVITY_CENTERED_BIT_KHR = 0x00000004,
VK_PRESENT_GRAVITY_MIN_BIT_EXT = VK_PRESENT_GRAVITY_MIN_BIT_KHR,
VK_PRESENT_GRAVITY_MAX_BIT_EXT = VK_PRESENT_GRAVITY_MAX_BIT_KHR,
VK_PRESENT_GRAVITY_CENTERED_BIT_EXT = VK_PRESENT_GRAVITY_CENTERED_BIT_KHR,
} VkPresentGravityFlagBitsKHR;// Provided by VK_EXT_surface_maintenance1
// Equivalent to VkPresentGravityFlagBitsKHR
typedef VkPresentGravityFlagBitsKHR VkPresentGravityFlagBitsEXT;Description
-
VK_PRESENT_GRAVITY_MIN_BIT_KHR means that the pixels will gravitate towards the top or left side of the surface.
-
VK_PRESENT_GRAVITY_MAX_BIT_KHR means that the pixels will gravitate towards the bottom or right side of the surface.
-
VK_PRESENT_GRAVITY_CENTERED_BIT_KHR means that the pixels will be centered in the surface.
If the value in VkSurfaceCapabilitiesKHR::currentTransform is
not VK_SURFACE_TRANSFORM_IDENTITY_BIT_KHR, it is
implementation-defined whether the gravity configuration applies to the
presented image before or after transformation.
