(This is the legacy documentation for SDL2, the previous stable version; SDL3 is the current stable version.)
SDL_HINT_RENDER_LINE_METHOD
A variable controlling how the 2D render API renders lines
Defined in SDL_hints.h
Syntax
#define SDL_HINT_RENDER_LINE_METHOD "SDL_RENDER_LINE_METHOD"
This variable can be set to the following values:
- "0": Use the default line drawing method (Bresenham's line algorithm as of SDL 2.0.20)
- "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, was the default before 2.0.20)
- "3": Use the driver geometry API (correct, draws thicker diagonal lines)
This variable should be set when the renderer is created.
