How to draw image on a window?
9
I have created a window with createwindow() api using VS2005 in C++ on Windows Vista
My requirement is to draw an image (of any format) on that window. I am not using any MFC in this application.

not exactly sure what is your problem: draw a bitmap on the form, or you would like know how to work with various image formats, or both. Anyways below is an example of how you could load a bitmap and draw it on the form:
HBITMAP hBitmap = NULL;
LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
int wmId, wmEvent;
switch (message)
{
<...>
case WM_CREATE:
hBitmap = (HBITMAP)LoadImage(hInst, L"c:\test.bmp", IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE);
break;
case WM_PAINT:
PAINTSTRUCT ps;
HDC hdc;
BITMAP bitmap;
HDC hdcMem;
HGDIOBJ oldBitmap;
hdc = BeginPaint(hWnd, &ps);
hdcMem = CreateCompatibleDC(hdc);
oldBitmap = SelectObject(hdcMem, hBitmap);
GetObject(hBitmap, sizeof(bitmap), &bitmap);
BitBlt(hdc, 0, 0, bitmap.bmWidth, bitmap.bmHeight, hdcMem, 0, 0, SRCCOPY);
SelectObject(hdcMem, oldBitmap);
DeleteDC(hdcMem);
EndPaint(hWnd, &ps);
break;
case WM_DESTROY:
DeleteObject(hBitmap);
PostQuitMessage(0);
break;
default:
return DefWindowProc(hWnd, message, wParam, lParam);
}
return 0;
}
LoadImage loads an icon, cursor, animated cursor, or bitmap. Details here
For working with various images formats you can use Windows Imaging Component (see IWICBitmapDecoder) or code from here Loading JPEG and GIF pictures or 3rd party tools like FreeImage or LeadTools
hope this helps, regards

Hi Serge, it solved my problem of drawing image on window. thanks for the help. but as this takes only bmp,cur and ico files, i need to work on converting png to bmp and then i will pass that bmp to this function

If I can save someone a few minutes of searching around, I tried using this answer but it didn't work. After a while of poking I tried to change the sizeof(bitmap) to sizeof(BITMAP) and the code worked. I'm using Visual Studio 2015 on Windows 10. Heres the full line : GetObject(hBitmap, sizeof(BITMAP), &bitmap);

And the leaked HDC that was never released upon function exit? Windows GDI rules 101: If you Get it, then Release it; if you Create it, then Delete it. You did this correctly with your brush (Create/Delete), but failed to do so with your client DC (Get/Release).

Ah, thanks :) I resolved it. Just added one line before closing the curly bracket. ReleaseDC(hWnd, hdc);
