Using png for PictureMarkerSymbol

mody_buchbinder

By the docs you can create PicyureMarkerSymbol from bmp and emf files only.
Is there a way to create PictureMarkerSymbol from png file?

Thanks

Hi, Mody!
Certainly you can create such a PictureMarkerSymbol. You should use the Bitmap class to load the image and then pass it to the Picture property of the IPictureMarkerSymbol object.

Code:
Bitmap bitmap=new Bitmap(image_path);
IPictureMarkerSymbol symbol=new PictureMarkerSymbolClass();
symbol.Picture=(stdole.IPictureDisp)ESRI.ArcGIS.ADF.COMSupport.OLE.GetIPictureDispFromBitmap(bitmap);

Similarly you can create the IPictureMarkerSymbol object from any image format supported by the Bitmap class, i.e. bmp, jpg, gif, exif, png, tiff. Even icons can be used for it (see the Bitmap.FromHicon method documentation).
