For the raster image you can build pyramid with gdaladdo, it's really useful
to increase performances

 large.
  Can the data in image $rmap be accessed for layer resource directly,

 Vince,

 There are no mechanisms to utilize a PHP image object as the
 data in a mapserver raster layer without first writing to disk.  I
 gather PHP image resources are actually a handle to a gdImage
 object, so if you needed it badly enough it should be possible to
 write a PHP function that turn that gdImage into something that
 was accessable to GDAL as a raster but that would be quite
 involved and not something likely to go back into the core
 distribution.

 Best regards,

[mapserver-users] Edit a Line shape and save it

[Mohamed Saâd HESSANE]

Hy everybody,
I work with python mapscript and i want to create a Line shape.
I do this :
   test = mapscript.shapefileObj('test',mapscript.MS_SHAPEFILE_ARC)
   for i in range(len(x))
  test.addPoint(mapscript.pointObj(x[i],y[i],0,0))

When i execute the script, there is two new file in the script directory
(test.shp and test.shx).
But when i do an ogrinfo, there's no data stored in the file :
   $ogrinfo -al test.shp
   INFO: Open of `test.shp'
 using driver `ESRI Shapefile' successful.

   Layer name: test
   Geometry: Line String
   Feature Count: 0
   Extent: (0.00, 0.00) - (0.00, 0.00)
   Layer SRS WKT:
   (unknown)

can you help me please?
