Before you begin:
The code is based on custom GDI+ class. Download the class module first and save it in gdiplus.prg file.

Call this code from a method or event of a FoxPro form when that form is active, i.e. posesses the keyboard focus.

    Anatoliy,

    I am creating a thematic map of the United States. It consists of a container object on a form. The container object contains shape objects in the form of each state in the U.S.

    I would like to save the image of the map to a .BMP, .JPG or .PNG without making the form visible. How do I do this?

    I am having trouble finding the gdiplus.prg you refer to in your code setup. Please tell me exactly where I might find this program. I have looked everywhere.

    Perhaps this program was outmoded by the new GDIPlusX.vcx class library and is no longer available. If so, please adjust your code to work with it.

    Thanks!

    Hugh,

    There's a link to this code in Before You Begin section on this page

    http://www.news2news.com/vfp/?example=450

    This GDI+ library is not freeware though. It is also not compatible with GDI+ FFC code, since I have decided to create this library from scratch.
