Is there any way to draw a PNG image on window without using MFC?
I am developing a Windows API application without using MFC. I am using standard Windows libraries.
How do I draw a PNG image in a window?
Help me with some sample code.
I have tried some codes which are available on the Internet开发者_如何学C, but all are using MFC.
Take a look at this StackOverflow question. It offers several options which should meet your needs.
Adapted from MSDN:
#include <windows.h>
#include <gdiplus.h>
#include <stdio.h>
using namespace Gdiplus;
void draw()
{
// start up GDI+ -- only need to do this once per process at startup
GdiplusStartupInput gdiplusStartupInput;
ULONG_PTR gdiplusToken;
GdiplusStartup(&gdiplusToken, &gdiplusStartupInput, NULL);
Rect rect(20,20,50,50);
Graphics grpx(dc);
Image* image = new Image(L"SomePhoto.png");
grpx.DrawImage(Img,rect);
delete image;
// shut down - only once per process
GdiplusShutdown(gdiplusToken);
return;
}
Your choices are: GDI+, WIC(Windows Imaging Component) or libpng
You can use GDI+. See Loading and Displaying Bitmaps.
The below code worked for me. It's free of MFC and can be used straight away to draw PNG images in a window.
Gdiplus::Image image(L"C:\\Logo.png") ;
Gdiplus::Graphics* graphics = Gdiplus::Graphics::FromHDC(GetDC(hWnd));
RectF ImgRect(0,0,y3/10,y3/10) ;
Gdiplus::Status result = graphics->DrawImage(&image, ImgRect);
Thanks for all your support and quick response to solve my problem.
If you know PNG'coding,you can decoding it. So you can draw PNG in any way~
