IMG_SavePNG_IO(3)

💖 IMG_SavePNG_IO(3) 💖

okay so hi bestie, welcome to IMG_SavePNG_IO(3) from SDL_image3 FUNCTIONS — yes, the manual name is folded in right here, we're not doing that copy-paste header line. This is the “save your SDL_Surface as PNG data through an SDL_IOStream” moment, and it's lowkey iconic. 🎀

🌸 NAME 🌸

IMG_SavePNG_IO — save an SDL_Surface into PNG image data, via an SDL_IOStream. That's the whole vibe. ✨

✨ SYNOPSIS ✨

#include <SDL3_image/SDL_image.h>

bool IMG_SavePNG_IO(SDL_Surface *surface, SDL_IOStream *dst, bool closeio);

🦋 DESCRIPTION 🦋

okay so the main character here is simple: if you just want to save to a filename, you can use IMG_SavePNG() instead. Like, don't do extra work for no reason, bestie. 💅

Now the important caveat: if closeio is true, dst will be closed before returning, whether this function succeeds or not. Whether. It. Succeeds. Or. Not. So yes, that stream is getting closed either way — no cap. Set it to false if you need to keep that SDL_IOStream open, okay? 🫶

🎀 FUNCTION PARAMETERS 🎀

• surface — the SDL_Surface to save. That's the image data you're trying to get out into PNG land. 🖼️
• dst — the SDL_IOStream to save the image data to. It's the destination stream, the little data pipe, the place the PNG bytes are headed. 🚰
• closeio — true to close/free the SDL_IOStream before returning, false to leave it open. So it's literally the “do we shut the door behind us?” switch. 🚪

🌈 RETURN VALUE 🌈

Returns true on success or false on failure; call SDL_GetError() for more information. So if things go sideways, don't just stare at it — hit up SDL_GetError() for the tea. ☕

💜 AVAILABILITY 💜

This function is available since SDL_image 3.0.0. Periodt. If you're on something older, this is not the function you're looking for, bestie. 🕰️
