vkCmdSetDiscardRectangleEXT - Set discard rectangles dynamically

Parameters

• CommandBuffer is the command buffer into which the command will be recorded.

• firstDiscardRectangle is the index of the first discard rectangle whose state is updated by the command.
• discardRectangleCount is the number of discard rectangles whose state are updated by the command.
• pDiscardRectangles is a pointer to an array of Rect2D structures specifying discard rectangles.

Description

The discard rectangle taken from element i of pDiscardRectangles replace the current state for the discard rectangle index firstDiscardRectangle + i, for i in [0, discardRectangleCount).

Valid Usage

• The sum of firstDiscardRectangle and discardRectangleCount must be less than or equal to PhysicalDeviceDiscardRectanglePropertiesEXT::maxDiscardRectangles

• The x and y member of offset in each Rect2D element of pDiscardRectangles must be greater than or equal to 0
• Evaluation of (offset.x + extent.width) in each Rect2D element of pDiscardRectangles must not cause a signed integer addition overflow
• Evaluation of (offset.y + extent.height) in each Rect2D element of pDiscardRectangles must not cause a signed integer addition overflow

Valid Usage (Implicit)

• CommandBuffer must be a valid CommandBuffer handle

• pDiscardRectangles must be a valid pointer to an array of discardRectangleCount Rect2D structures
• CommandBuffer must be in the recording state
• The CommandPool that CommandBuffer was allocated from must support graphics operations
• discardRectangleCount must be greater than 0

Host Synchronization

• Host access to CommandBuffer must be externally synchronized

• Host access to the CommandPool that CommandBuffer was allocated from must be externally synchronized
