Explanation

The IKWmfFileLoad function loads vector image data from a WMF file. If Width or Height are 0, the image will be loaded according to that size specifed in the WMF file.

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, Ik10File64A.dll section.

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

Note: When a vector 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.
