Is there a way that I dont have use any image library..
should be possible with ATL::CImage.
should support it.
GDI is a software library and its algorithms are written
for speed, not quality. Using a third-party (or open source)
library is one solution. The other is using DirectX. Since
DirectX delegates everything to the hardware, you'll get
much better performance (though an OpenGL-based third
party library will pretty much do the same using the OpenGL
driver so look for those if you want, but beware that Vista
has no hardware OpenGL driver). Then again perhaps you
don't care about performance...

Hi
I am having a requirement to display an image . Image can be of any of
formats(jpg,bmp,png).
I have decided to use ATL::CImage . My application is full screen
application, it will not be having any scrollbars. and the image needs
to be fit in screen. Using it I am able to display image but problem
is coming when I try to load image larger than screen, some part of
image is clipped.To show full image I tried to use StretchBlt function
but using that makes image low quality and distorted.
My code is as:
wstring szPath(L"C:\\Pics\\2.jpg");
if(!m_Image.IsNull())
m_Image.Destroy();
m_Image.Load(szPath.c_str());
HDC hDC=::GetDC(m_hWnd);
WTL::CRect rcClient;
GetClientRect(&rcClient);
m_Image.StretchBlt(hDC,
0,0,rcClient.Width(),rcClient.Height());
Is there any solution to resize the image without distorting it.Or I
need to use some open source library.
Any suggestions will help..
