[Cartoweb-users] export pdf - legend error - WMS as layer source

[Oliver Christen]

one possible solution would be to define a specific 24bit color output  and force your wms layer to use it thought the metadata parameter, you loose the transparency though.

  hello -

    i  have added the legend template block to exportpdf.ini as per
  cartoweb3/projects/test_main/client_conf/exportPdf.ini)

   all goes well however i get an error if if a wms layer is turned on -  and i try to print to pdf

  the layer in question mtrans gets its legend graphic from the  source as defined in the .map file :

  "wms_legend_graphic"  "true"

  the web error i get is 

  http://tundra.geog.utoronto.ca/cartoweb/CUSIMANO1.php?mode=pdf

  FPDF error: Alpha channel not supported: /opt/www/cartoweb3/htdocs/generated/icons/CUSIMANO1/CUSIMANO1/mtrans.png

  if i would add SLD definitions to the mapfile woud
   my pdf legend then be able to add this layer or is there another work around ?

  many thanks
  mariange
