This example shows how to save a bitmap in LabWindos/CVI. There are two example programs, one for CVI 5.0 and another for CVI 5.5.

Both programs save a control or a panel from the .UIR to a bitmap file.

The CVI 5.0 program gets a bitmap of the object, copies it to the clipboard, and then saves the bitmap to a file using GetCtrlDisplayBitmap and SetBitmapToFile defined in the File.OBJ. This program uses SDK functions already compiled in an OBJ file that must be included with the project. Make sure to use the OBJ file that corresponds to CVI's compatibility mode (in the Project window under Options>>Compilier Options).

LabWindows/CVI 5.5-7.1: This program uses functions from the Programmer's Toolbox available in LabWindows/CVI 5.5 and higher. These functions are SavePanelDisplayToFile and SaveCtrlDisplayToFile. As you can see in the file demo.c, you have the choice of using these functions or using SavePanelDisplayBitmap and SaveCtrlDisplayBitmap then using SaveBitmapToFile to save the bitmap to disk instead. (you would need to comment out the functions SavePanelDisplayToFile and SaveCtrlDisplayToFile)

The format of *.fp has changed from CVI 5.0 to CVI 5.5, attempting to use the fp in CVI 5.0 will not work. Also using the OBJ file from the CVI 5.0 example will not work in CVI 5.5.
