vkCmdSetLineWidth(3)

# vkCmdSetLineWidth(3) Manual Page

## Name

vkCmdSetLineWidth - Set the dynamic line width state

## C Specification

Each line segment has an associated width. The line width is specified by the VkPipelineRasterizationStateCreateInfo::`lineWidth` property of the currently active pipeline, if the pipeline was not created with `VK_DYNAMIC_STATE_LINE_WIDTH` enabled.

Otherwise, the line width is set by calling `vkCmdSetLineWidth`:

    void vkCmdSetLineWidth(
        VkCommandBuffer                             commandBuffer,
        float                                       lineWidth);

## Parameters

- `commandBuffer` is the command buffer into which the command will be recorded.

- `lineWidth` is the width of rasterized line segments.

## Description

Valid Usage

- The bound graphics pipeline must have been created with the `VK_DYNAMIC_STATE_LINE_WIDTH` dynamic state enabled

- If the wide lines feature is not enabled, `lineWidth` must be `1.0`

Valid Usage (Implicit)

- `commandBuffer` must be a valid VkCommandBuffer handle

- `commandBuffer` must be in the recording state

- The `VkCommandPool` that `commandBuffer` was allocated from must support graphics operations

Host Synchronization

- Host access to `commandBuffer` must be externally synchronized

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