The IsEPS property returns True if the bitmap is a placeholder in the EPS format.
Examples:
The following VBA example searches for a header in the EPS format. If one is found, it is selected.
Sub Test()
Dim s As Shape
For Each s In ActivePage.Shapes
s.Selected = False
If s.Type = cdrBitmapShape Then
If s.Bitmap.IsEPS Then s.Selected = True
End If
Next s
End Sub
