The picture as a background image is visible but not editing.

The main use of Function:

Background to draw raster. Details are as follows:

parameter	Explanation
BSTR sFileName	Raster file file path .DWGBMPJPG
LONG lLeftUpX	Upper left corner of the window coordinates X, the viewport displayed in the viewing zone control gate shown in FIG.
LONG lLeftUpY	FIG upper left position of the gate in the control displayed on the display viewing zone Y, the viewport window coordinates

js implemented Definitions:

BackgroundImage function () { 
    // Create a COM component object 
    var getPt = mxOcx.NewComObject ( "IMxDrawUiPrPoint"); 
    getPt.message = "midpoint insertion point to take a picture"; 
    IF (! getPt.go () =. 1) { 
        return; 
    } 
    var frstPt getPt.value = (); 
    IF (frstPt == null) { 
        return; 
    } 
    // control program in the disk file path 
    var sImageFile mxOcx.GetOcxAppPath = () + "\\ mxcad.jpg"; 
    Alert (sImageFile); 
    // manufactured by drawing a marker object image 
    // parameter is a raster image file .DWGBMPJPG file path; two for the upper left position parameter X displayed on the display of the gate in FIG control viewport, the viewport window coordinates ; 
    // three parameters for the Y position of the upper left corner of the grid shown in FIG display control viewport, the viewport window coordinates; 
    mxOcx.DrawImageToBackground (sImageFile, frstPt.x, frstPt.y);
