Large ShapeFile printing problem

#1

 Hi,


I'm trying to print large shape file (200 MB). 


I use "Large Scale Map Printing"  sample codes.


Print preview and printing works fine, The problem ist MapPrinterLayer doesn't show the shape .


I don't see this problem with small shapes.


Thanks in advance.

Hi Shaahin, 
  
 Sorry the the confusing, please use the development branch 6.0.348.0 which works fine, the release branch 6.0.0.348 does not support the GeoLinearGradientBrush in PrinterGeoCanvas, so you got the exception.
