Hello all,
I am working in VC++ 2005
I need to draw somethig and save it as a jpeg, without showing it on the
screen.
So in other words, I need to draw on a DC and save the contents of the DC as
a jpeg. How do I do this? The CImage class? But how do I exactly do this
particular thing with it?
Thanks
Srishti

You can use CImage to that.

CImage Image;
Image.Create(...);

CDC *pDC = CDC::FromHandle(Image.GetDC());

pDC->MoveTo(....);
pDC->LineTo(...);

Image.ReleaseDC();

Image.Save(....);

Thanks a lot... That worked perfectly fine!!! I was trying something similar,
but I thing I was getting stuck on the line
Image.Save(_T("myImage.jpg", ImageFormatJPEG );
the compiler says that ImageFormatJPEG is an undeclared identifier!! But it
savs it as jpeg if I don't mention a second parameter!

What is wrong with "ImageFormatJPEG"

Thanks you soooo much
