vkCmdSetAlphaToCoverageEnableEXT
Specify the alpha to coverage enable state dynamically for a command buffer
To dynamically set the
alphaToCoverageEnable state, call:
void vkCmdSetAlphaToCoverageEnableEXT(
VkCommandBuffer commandBuffer,
VkBool32 alphaToCoverageEnable);
commandBufferis the command buffer into which the command will be recorded.alphaToCoverageEnablespecifies thealphaToCoverageEnablestate.
This command sets the alphaToCoverageEnable state for subsequent
drawing commands
when drawing using shader objects, or
when the graphics pipeline is created with
VK_DYNAMIC_STATE_ALPHA_TO_COVERAGE_ENABLE_EXT set in
VkPipelineDynamicStateCreateInfo::pDynamicStates.
Otherwise, this state is specified by the
VkPipelineMultisampleStateCreateInfo::alphaToCoverageEnable
value used to create the currently active pipeline.
