Hi,

it's just copy&paste, compile and test .... so why not trying it?

And if you look to the code you'll see it does not use any AutoCAD-lib-functions. so it's independent from any AutoCAD-version (it just reads the icon-part of the image header)

I am not looking for what you have suggested means using with out autocad.

I would like to use AutoCAD API for getting thumbnail. (Message 2).

Please advise.

Thanks is advance.....

Hi,

Why do you have to use the AutoCAD API if you can get the same result without it?

if you want to calculate sin(alpha) ... what could be the reason for doing that with a specific API from AutoCAD instead of the global Math-namespace?

Sorry if I bother you, I'd like to understand why doing something more complex that can be achieved in an easy way (ready to use and independet from any AutoCAD release).
