# Load image from container
Set Variable [ $image ; Value: MBS( "GMImage.New"; "500x500"; "transparent" ) ]
# turn on alpha channel and set background to transparent
Set Variable [ $r ; Value: MBS( "GMImage.SetType"; $image; 7 ) ]
Set Variable [ $r ; Value: MBS( "GMImage.SetBackgroundColor"; $Image; "transparent" ) ]
# read SVG
Set Variable [ $r ; Value: MBS( "GMImage.ReadContainer"; $image; SVG to PNG::InputFile; "500x500"; 0; "SVG" ) ]
# Output to container and release image
Set Field [ SVG to PNG::OutputFile ; MBS( "GMImage.WriteToPNGContainer"; $image; "test.png") ]
Set Variable [ $r ; Value: MBS("GMImage.Free"; $image) ]

Try GraphicsMagick in file WMF Conversion

Set Variable [ $image ; Value: MBS( "GMImage.New"; "300x300"; "white" ) ]
Set Variable [ $r ; Value: MBS( "GMImage.SetMagick"; $image; "EMF") ]
Set Variable [ $r ; Value: MBS( "GMImage.ReadContainer"; $Image; WMF Conversion::Input WMF) ]
If [ MBS("IsError") ]
    Show Custom Dialog [ "Error" ; $r ]
