GDI+ 打开图片

1. GDI+初始化

Gdiplus::GdiplusStartupInput gdiplusStartupInput;

ULONG_PRT gdiplusToke;

Gdiplus::GdiplusStartup(&gdiplusStartupInput, &gdiplusToken, NULL);

 

2. 打开图片

Gdiplus::Image image(“filepath”);

if(image.GetLastStatus() != Gdiplus::Ok){

    error(1);

}

 

3.创建兼容DC

Gdiplus::Graphics graphics(hDC);

graphics.DrawImage(&image, 0, 0, RectWidth(lprcBmp),RectWidth(lprcBmp));

 

4.卸载GDI+

graphics.ReleaseDC(NULL);
