NAME¶

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

SYNOPSIS¶

#include <SDL3/SDL_hints.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.
