How to make a picture marker symbol (ArcObjects .NET 10.6 SDK)

Summary

The code example in this topic shows how to create a picture marker symbol.

Making a picture marker symbol

A picture marker symbol can be created using either a Windows bitmap (BMP) or enhanced metafile (EMF) as the underlying artwork for the symbol. The following code shows an example for using both types of files as the input. You need to modify the input path for each type to point to the appropriate file.

[VB.NET]

Public Sub PictureMarkerSymbol()
    ' This example creates two picture marker symbols; one from a .emf file
    ' and one from a .bmp file.
    
    ' Set the transparent background color for the .bmp-based picture marker symbol to white.
    Dim rgbColorCls As ESRI.ArcGIS.Display.IRgbColor=New ESRI.ArcGIS.Display.RgbColorClass
    rgbColorCls.Red=255
    rgbColorCls.Green=255
    rgbColorCls.Blue=255
    
    ' Create the EMF marker and assign properties.
    Dim emfPictureMarkerSymbolCls As ESRI.ArcGIS.Display.IPictureMarkerSymbol=New ESRI.ArcGIS.Display.PictureMarkerSymbolClass
    With emfPictureMarkerSymbolCls
        .CreateMarkerSymbolFromFile(ESRI.ArcGIS.Display.esriIPictureType.esriIPictureEMF, "c:\temp\mypict.emf")
        .Angle=0
        .Size=24
        .XOffset=0
        .YOffset=0
    End With
    
    ' Create the bitmap marker and assign properties.
    Dim bitmapPictureMarkerSymbolCls As ESRI.ArcGIS.Display.IPictureMarkerSymbol=New ESRI.ArcGIS.Display.PictureMarkerSymbolClass
    With bitmapPictureMarkerSymbolCls
        .CreateMarkerSymbolFromFile(ESRI.ArcGIS.Display.esriIPictureType.esriIPictureBitmap, "c:\temp\mypict.bmp")
        .Angle=0
        .BitmapTransparencyColor=rgbColorCls
        .Size=32
        .XOffset=0
        .YOffset=0
    End With
    
End Sub

[C#]

public void PictureMarkerSymbol()
{
    // This example creates two picture marker symbols; one from a .emf file and 
    // one from a .bmp file.

    // Set the transparent background color for the .bmp-based picture marker symbol to white.
    ESRI.ArcGIS.Display.IRgbColor rgbColorCls=new
        ESRI.ArcGIS.Display.RgbColorClass();
    rgbColorCls.Red=255;
    rgbColorCls.Green=255;
    rgbColorCls.Blue=255;

    // Create the EMF marker and assign properties.
    ESRI.ArcGIS.Display.IPictureMarkerSymbol emfPictureMarkerSymbolCls=new
        ESRI.ArcGIS.Display.PictureMarkerSymbolClass();
    emfPictureMarkerSymbolCls.CreateMarkerSymbolFromFile
        (ESRI.ArcGIS.Display.esriIPictureType.esriIPictureEMF, 
        "c:\\temp\\mypict.emf");
    emfPictureMarkerSymbolCls.Angle=0;
    emfPictureMarkerSymbolCls.Size=24;
    emfPictureMarkerSymbolCls.XOffset=0;
    emfPictureMarkerSymbolCls.YOffset=0;

    // Create the bitmap marker and assign properties.
    ESRI.ArcGIS.Display.IPictureMarkerSymbol bitmapPictureMarkerSymbolCls=new
        ESRI.ArcGIS.Display.PictureMarkerSymbolClass();
    bitmapPictureMarkerSymbolCls.CreateMarkerSymbolFromFile
        (ESRI.ArcGIS.Display.esriIPictureType.esriIPictureBitmap, 
        "c:\\temp\\mypict.bmp");
    bitmapPictureMarkerSymbolCls.Angle=0;
    bitmapPictureMarkerSymbolCls.BitmapTransparencyColor=rgbColorCls;
    bitmapPictureMarkerSymbolCls.Size=32;
    bitmapPictureMarkerSymbolCls.XOffset=0;
    bitmapPictureMarkerSymbolCls.YOffset=0;
}
