Counting instances of an image

Hi there,


I can find which images are attached to my current drawing with the following code. However, I don't know how to find out how many times they are attached.


Anybody ?


Using tr As Transaction = db.TransactionManager.StartTransaction

		Dim nod As DBDictionary
		Dim imageDict As DBDictionary

		Console.WriteLine("Getting ACAD_IMAGE_DICT DB dictionary")
		nod = CType(tr.GetObject(db.NamedObjectsDictionaryId, OpenMode.ForRead, False), DBDictionary)
		imageDict = CType(tr.GetObject(nod.GetAt("ACAD_IMAGE_DICT"), OpenMode.ForRead, False), DBDictionary)

		For Each dicentry As DBDictionaryEntry In imageDict
			Dim myRasterImgDef As RasterImageDef = CType(tr.GetObject(CType(dicentry.Value, ObjectId), OpenMode.ForRead), RasterImageDef)

			If myRasterImgDef.IsLoaded Then
				Console.WriteLine("Found: " & myRasterImgDef.ActiveFileName)

				Console.WriteLine("Not found: " & myRasterImgDef.SourceFileName)
			End If


	Catch ex As Exception
		System.Windows.Forms.MessageBox.Show(ex.ToString, "Configurator", System.Windows.Forms.MessageBoxButtons.OK, System.Windows.Forms.MessageBoxIcon.Stop)
	End Try

End Using

 Thanx in advance

You need to search for raster reference entities of type RasterImage. There are two options I know for this, depending on your requirements: 1. Use Editor.SelectAll(), passing in a SelectionFilter with the appropriate dxf code. This is easiest but will only work in the current layout. Note: You might also need to zoom extents for this to work, i can't remember if you need to. 2. Iterate your block table records looking for RasterImage entities, using a counter. Advantage with this approach is that you can iterate your model space as well as all of your paper space block table records - i.e. you will get all of them.

Will give option 2 a shot, seems the most appropriate indeed.


If you happen to have an example for this iteration ,great, if not, I'll figure it out by myself ;-)
