v10 v11 141 141 }}} 142 142 143 This does executes a buffer on the geometry before rendering (see test.buffer.png attachment). Because of where the GEOMTRANSFORMATION processing occurs this processing happens '''after''' the feature is converted from map to image coordinates, but the effect is still valuable. In the future we might consider implementing a GEOMTRANSFORM at the layer level so that the transformation is available to all classes and/or styles (and consequently in query modes too).143 This does executes a buffer on the geometry before rendering (see test.buffer.png attachment). Because the GEOMTRANSFORM processing occurs this transformation happens '''after''' the feature is converted from map to image coordinates, but the effect is still valuable and the buffer value is given in pixels. In the future we might consider implementing a GEOMTRANSFORM at the layer level so that the transformation is available to all classes and/or styles (and consequently in query modes too). 144 144 145 145 == Expression Use Elsewhere == … … 161 161 A great deal of code would be made obsolete if this were pursued. Much of the OWS filter evaluation would be handled by the msQueryByFilter() function and numerous associated enums, defines, etc... could go away. 162 162 163 Grammar summary: 164 163 165 Logical operators: AND, OR, NOT[[BR]] 164 166 Comparison operators: =, '''=*''', !=, >, <, >=, <=, ~, '''~*''', in[[BR]] … … 176 178 2) All OGC filter operations need to be supported. Bounding box filters in particular have not been looked at.[[BR]] 177 179 3) Need ''LIKE'' operator code.[[BR]] 178 4) Need to finish msQueryByFilter() implementation.[[BR]] 179 5) How to handle projections?[[BR]] 180 6) Best way to manage tokens, array, list, tree?
