stephan@139: Currently there are some restrictions in the usage of the converter:
stephan@139: 
stephan@139: Supported datasources:
stephan@139: 
stephan@139:  * ArcSDE-passwords cannot be read since they are encrypted. The converter
rrenkert@182:    exports the string "define me" which needs to be replaced later on in the
rrenkert@182:    resulting mapfile
stephan@139: 
rrenkert@182:  * Since the MapServer cannot use a file geodatabase datasource the converter
rrenkert@182:    does not support this datasource and will not transform the MXD-file at all.
rrenkert@182: 
rrenkert@182:  * Raster data is not supported by the converter yet.
rrenkert@182: 
rrenkert@182: Symbol support:
rrenkert@182: 
rrenkert@182:  * Line symbols with pattern cannot be combined with marker symbols. The
rrenkert@182:    converter reads all symbols and writes the corresponding styles to the
rrenkert@182:    resulting mapfile but the marker symbols are rendered without any gap.
rrenkert@182: 
rrenkert@182:    * Workarround:
rrenkert@182:      For small marker symbols it is recommended to use a line symbol in
rrenkert@182:      combination with pattern (in ArcGIS called template) to create the
rrenkert@182:      symbology.
rrenkert@182:      The reason why marker symbols cannot be used in combination with a template
rrenkert@182:      is the difficulty to interpret the read attributes like marks and gaps and
rrenkert@182:      write the appropriate symbols with the appropiate gap to the mapfile.
rrenkert@182: 
rrenkert@182:  * The converter sets the width to 1 for line symbols that have a width
rrenkert@182:    smaller than 1. Outlines with a width smaller than 1 are drawn in the fill
rrenkert@182:    color of the ploygon and the width is set to 1.
rrenkert@182: 
rrenkert@183:    * Tip:
rrenkert@183:      To avoid lines and line colors (specially outlines) to be handled by the
rrenkert@183:      converter, use integer numbers for line width only.
rrenkert@183: 
rrenkert@182:  * Picture symbols are not supported by the converter.
rrenkert@182: 
rrenkert@182:  * In ArcGIS maps default symbols can be defined as fallback. Since MapServer
rrenkert@182:    does not support such fallback symbols or styles the converter does not
rrenkert@182:    read these default symbols.
rrenkert@182: 
rrenkert@182:  * In ArcGIS predefined symbols like bars or pie charts can be used to display
rrenkert@182:    values. The converter does not support these symbols.
rrenkert@182: 
rrenkert@183: Layer support:
rrenkert@183: 
rrenkert@183:  * Grouplayer with more than  one group level are not supported by the MapServer
rrenkert@183:    and even not by the converter.
