[C++Builder] HANDLE IKEmfFileLoad(LPCTSTR FileName, long Width, long Height, IKPROCESSPROC UserProc, LPCTSTR Caption, LPCTSTR Message, LPCTSTR Button);

[Delphi] function IKEmfFileLoad(FileName: PChar; Width, Height: Longint; UserProc: LONG_PTR; Caption, Message, Button: PChar): THandle;

Parameters

Name	Explanation
FileName	The name of the image file that is loaded into the memory
Width	The width of the loaded image (in pixels)
Height	The height of the loaded image (in pixels)
UserProc	The address of the user function (If not using the user function then set to 0)
Caption	Sets the text displayed in the title bar of the progress dialog box
Message	Sets the message displayed in the progress dialog box
Button	Sets the name of the button displayed in the progress dialog box

Explanation

The IKEmfFileLoad function loads vector image data from an EMF file. If the Width and Height parameters are 0 or less then the size will be taken from the EMF file header.

If the user function is set or if the Caption, Message, and Button parameters are blank then the Progress dialog box is not displayed. If the Progress dialog box is displayed, it indicates the percentage of the current process completed. For more information about the user function please refer to the Definition of User Function in the Ik10File.dll, Ik10FileA.dll, Ik10File64.dll, and Ik10File64A.dll section.

To execute this function, you must first execute the Ik10VectCom.dll, the Ik10VectComA.dll, the Ik10VectCom64.dll, or the Ik10VectCom64A.dll's IKVectorGdipStartfunction.

Note: When the EMF image is loaded, the ratio of the height and width of the original image is maintained and the largest pixel size of the image is scaled within the area defined by the Height and Width parameters.
