IKDxfFileLoadMem

This function loads a vector image from DXF format raw image data.

[C++Builder/Visual C++] HANDLE IKDxfFileLoadMem(HANDLE Handle, long Width, long Height, IKPROCESSPROC UserProc, LPCTSTR Caption, LPCTSTR Message, LPCTSTR Button);

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

[Visual Basic] Function IKDxfFileLoadMem(ByVal Handle As Long, ByVal Width As Long, ByVal Height As Long, ByVal UserProc As Long, ByVal Caption As String, ByVal Message As String, ByVal Button As String) As Long

Parameters

Name	Explanation
Handle	DXF format raw image data
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

Return Value

Returns the image handle of the vector image if successful. Returns False (0) if unsuccessful.

Explanation

This function loads a vector image from DXF format raw image data. When the Width is 0 or less, a value of 800 is used. When Height is 0 or less, a value of 600 is used. Entity types supported are: LINE, POINT, CIRCLE, TEXT, 3DFACE, POLYLINE, ARC, SOLID, and INSERT.

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 Ik9File.dll, Ik9FileA.dll, Ik9File64.dll, and Ik9File64A.dll section.

Except for the fact that the vector image is loaded from raw image data, this function operates in the same way as the IKDxfFileLoad function.

To execute this function, you must first execute the Ik9VectCom.dll, the Ik9VectComA.dll, the Ik9VectCom64.dll, or the Ik9VectCom64A.dll's IKVectorGdipStart function.

Note: When the DXF 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.
