# SDL\_HINT\_RENDER\_LINE\_METHOD(3)

A variable controlling how the 2D render API renders lines.

## NAME

SDL\_HINT\_RENDER\_LINE\_METHOD - A variable controlling how the 2D render API renders lines.

## HEADER FILE

Defined in SDL3/SDL\_hints.h

## SYNOPSIS

```
#include "SDL3/SDL.h"
```

**#define SDL\_HINT\_RENDER\_LINE\_METHOD** *SDL\_RENDER\_LINE\_METHOD"*

## DESCRIPTION

The variable can be set to the following values:

• "0": Use the default line drawing method (Bresenham's line algorithm)

• "1": Use the driver point API using Bresenham's line algorithm (correct,\
   draws many points)

• "2": Use the driver line API (occasionally misses line endpoints based on\
   hardware driver quirks

• "3": Use the driver geometry API (correct, draws thicker diagonal lines)

This hint should be set before creating a renderer.

## AVAILABILITY

This hint is available since SDL 3.2.0.
