Hello,

I want to develop a magnifier window in my already existing graph view.

Problem:
The graph contains symbols of some component , sometimes the symbols are so large in quantity so i cant view them in a simple scroll, and if i want to see them all at a same time i have to zoom out the window,by doing that the size of symbols become so small that i cant view than easily.

Requirement:
To view them(symbols) i want to develop a magnifier window, so it will zoom that part where i want to see the component.

Similar example (Working example)
In adobe reader we have a thumbnail view of all pages on left side, here we have a magnifier window which we can re-size also.

please help me out , my application has build in MFC , and i am using csrollview class for this graph window.

You know, a wisely use of StretchBlt Function[^] would do the job.

Hi Pallini,
Thanks for reply, but i think for using that StretchBlt Function function i must have some image, but i am working with real-time graphical view, its not a static image. some another idea for that.

The image is on the screen. You may use that.
