[raylib] raylib with opencv

raylib와 opencv를 사용해 보자.

 

#include "raylib.h"
#include "opencv2/opencv.hpp"
 
using namespace cv;
 
int main(void)
{
    Mat cvimage = imread("palvin.jpg", IMREAD_COLOR_RGB);
 
   Image rayimage{};
    rayimage.width = cvimage.cols;
    rayimage.height = cvimage.rows;
    rayimage.format = PIXELFORMAT_UNCOMPRESSED_R8G8B8;
    rayimage.mipmaps = 1;
    rayimage.data = cvimage.ptr(); //(void*)(cvimage.data);
 
    const int screenWidth = 450;
    const int screenHeight = 500;
    InitWindow(screenWidth, screenHeight, "raylib example");
    SetTargetFPS(60);
 
    // NOTE: Textures MUST be loaded after Window initialization (OpenGL context is required)
    Texture2D texture = LoadTextureFromImage(rayimage);
 
    while (!WindowShouldClose())
    {
        BeginDrawing();
 
        ClearBackground(RAYWHITE);
 
        DrawTexture(texture, 10, 10, WHITE);
 
        EndDrawing();
    }
 
    //UnloadImage(rayimage);
    // LoadImage()로 로드한 이미지에만 사용.
    UnloadTexture(texture);
 
    CloseWindow();
 
    return 0;
}

 

raylib에서 texture는 윈도우가 생성된 이후 로드되어야 한다.
