(This is the documentation for SDL3, which is under heavy development and the API is changing! SDL2 is the current stable version!)

SDL_HINT_RENDER_LINE_METHOD

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

Header File

Defined in <SDL3/SDL_hints.h>

Syntax

#define SDL_HINT_RENDER_LINE_METHOD "SDL_RENDER_LINE_METHOD"

Remarks

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.

Version

This hint is available since SDL 3.0.0.
