C Specification

To dynamically enable or disable writes to a color attachment, call:

// Provided by VK_EXT_color_write_enable
void                                    vkCmdSetColorWriteEnableEXT(
    VkCommandBuffer                             commandBuffer,
    uint32_t                                    attachmentCount,
    const VkBool32*                             pColorWriteEnables);

Parameters

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

  • attachmentCount is the number of VkBool32 elements in pColorWriteEnables.

  • pColorWriteEnables is a pointer to an array of per target attachment boolean values specifying whether color writes are enabled for the given attachment.

Description

This command sets the color write enables for subsequent drawing commands when the graphics pipeline is created with VK_DYNAMIC_STATE_COLOR_WRITE_ENABLE_EXT set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkPipelineColorWriteCreateInfoEXT::pColorWriteEnables values used to create the currently active pipeline.

Valid Usage
  • VUID-vkCmdSetColorWriteEnableEXT-None-04803
    The colorWriteEnable feature must be enabled

  • VUID-vkCmdSetColorWriteEnableEXT-attachmentCount-06656
    attachmentCount must be less than or equal to the maxColorAttachments member of VkPhysicalDeviceLimits

Valid Usage (Implicit)
  • VUID-vkCmdSetColorWriteEnableEXT-commandBuffer-parameter
    commandBuffer must be a valid VkCommandBuffer handle

  • VUID-vkCmdSetColorWriteEnableEXT-pColorWriteEnables-parameter
    pColorWriteEnables must be a valid pointer to an array of attachmentCount VkBool32 values

  • VUID-vkCmdSetColorWriteEnableEXT-commandBuffer-recording
    commandBuffer must be in the recording state

  • VUID-vkCmdSetColorWriteEnableEXT-commandBuffer-cmdpool
    The VkCommandPool that commandBuffer was allocated from must support graphics operations

  • VUID-vkCmdSetColorWriteEnableEXT-videocoding
    This command must only be called outside of a video coding scope

  • VUID-vkCmdSetColorWriteEnableEXT-attachmentCount-arraylength
    attachmentCount must be greater than 0

Host Synchronization
  • Host access to commandBuffer must be externally synchronized

  • Host access to the VkCommandPool that commandBuffer was allocated from must be externally synchronized
