Armin,
With your aid and a some test and error =), I'm doing some progress with the
implementation of my small application. Thank you very much.
1) Now I'm trying to label some XYLAYER points with data available in the
RESULT_FIELDS.
I want to use one result field (TEXTID) for the text label and other result
field (SENTIDO, in degrees, from 0 to 360) to give the angle to the label.
In the XYLAYER of my mapfile I have defined:
.....
METADATA
.....
"RESULT_FIELDS" "TEXTID,LATITUD,LONGITUD,SENTIDO,....."
"RESULT_HEADERS" "Etiqueta,Latitud,Longitud,Rumbo,....."
.....
END # Metadata
.....
LABELITEM "TEXTID"
# LABELITEM "Etiqueta"
LABELANGLEITEM "SENTIDO"
# LABELANGLEITEM "Rumbo"
LABELCACHE ON
POSTLABELCACHE TRUE
.....
I am making some error? Is possible to do what i want to do?
2) Another question, I have my map in geographic coordinates (UNITS DD) and
the showCoords() function displays something like
X: -60
Y: -60
that is, only the integer part of the longitude (xcoord). Is there a way to
display lat/lon coordinates? In degrees or in decimal degrees?
Thank you in advance.
Gaston.
