BUG
When an ArcMap generated EPS, PDF, CGM, or AI Illustrator file is opened in an external editor, like Adobe Illustrator, some large polygons are divided into thin vertical strips.The Adobe Illustrator export format was not available until ArcGIS 8.1 Service Pack 1.
This is called polygon dicing, and is implemented on polygons containing more than 20,000 vertices. The purpose is to speed up on-screen drawing and output to a printer.
Code:
Public Sub turnOffDicing()
Dim pGeometryEnv As IGeometryEnvironment3
Set pGeometryEnv = New GeometryEnvironment
pGeometryEnv.DicingEnabled = False
End Sub
Warning:
This code will not work with CGM files. Unexpected results can occur when exporting to CGM with polygon dicing turned off.
Code:
Public Sub turnOnDicing()
Dim pGeometryEnv As IGeometryEnvironment3
Set pGeometryEnv = New GeometryEnvironment
pGeometryEnv.DicingEnabled = True
End Sub
Warning:
Turn polygon dicing back on after exporting, otherwise screen drawing and printing performance may slow considerably.
