💖 SDL_SetClipRect 💖

okay bestie, welcome to the SDL API Reference page for SDL_SetClipRect — she's giving main character energy in the 3 section of the manual and honestly? iconic. sit down, grab a strawberry 🍓, we're learning about clipping rectangles.

🌸 NAME 🌸

SDL_SetClipRect — sets the clipping rectangle for a surface. no cap, that's literally her whole job. 💅

✨ SYNOPSIS ✨

#include "SDL.h"

void SDL_SetClipRect(SDL_Surface *surface, SDL_Rect *rect);

like, look at that signature. two pointers, zero return value, pure vibes. 🦋

🎀 DESCRIPTION 🎀

So here's the tea, bestie: SDL_SetClipRect sets the clipping rectangle for a surface. And what does that even mean? Okay so when this surface is the destination of a blit, only the area within the clip rectangle will be drawn into. everything outside it just... doesn't get drawn. it's giving "you can sit with us but only in this specific region." 😭

The rectangle that rect points to gets clipped to the edges of the surface, so the clip rectangle for a surface can never fall outside the edges of the surface. the surface said boundaries, and she meant it. 🫶

And if rect is NULL? then the clipping rectangle gets set to the full size of the surface. whole thing, no restrictions, free the nipple but for pixels. ✨

not me being obsessed with how tidy this function is. one call, whole surface scoped. periodt. 👑
