說明:

int SDL_SoftStretch(SDL_Surface *src, const SDL_Rect *srcrect, SDL_Surface *dst, const SDL_Rect *dstrect) |
main.c
#include <stdio.h> #include <stdlib.h> #include <SDL.h> int main(void) { SDL_Surface *screen = NULL; SDL_Init(SDL_INIT_VIDEO); screen = SDL_SetVideoMode(400, 240, 16, SDL_HWSURFACE); SDL_Surface* bmp = SDL_LoadBMP("sdmc:/3ds/main.bmp"); SDL_SoftStretch(bmp, NULL, screen, NULL); SDL_Flip(screen); SDL_Delay(3000); SDL_FreeSurface(bmp); SDL_Quit(); return 0; }
P.S. 圖片像素格式必須跟SDL_SetVideoMode()一致,可以使用ffmpeg -i src.jpg -pix_fmt rgb565 -y dst.bmp轉換或者使用SDL_ConvertSurface()轉換
完成
