Creating a map Request

Understanding map Request Parameters
The following sections cover some of the map-request parameters in more
detail than the table on page 13.
LAYERS Parameter
To locate an MWF file, Autodesk MapGuide LiteView concatenates the MWF
name specified in the map request and the value of that MWFSearchPath
parameter specified in
config.ini . MWFSearchPath can contain multiple path
names, each of which Autodesk MapGuide LiteView prefixes onto the
LAYERS value and uses to search for the MWF file. Locked layers cause map
and feature_info requests to fail. To specify the value of the LAYERS param-
eter in a request, use either the file name or the relative path and file names
of an MWF. You can omit the
.mwf extension.
HLS Optional. Specifies one of the highlighting
styles (line thickness, line style, and so on)
that are defined by the
config.ini file’s own
HLS parameter(s). Autodesk MapGuide Lite-
View assigns a default style if this parameter
is omitted. For more information about
con-
fig.ini’s HLS parameter, see Chapter 3, “Con-
figuring Autodesk MapGuide LiteView,” in
the
Autodesk MapGuide LiteView Servlet
Administrator’s Guide .
An integer between 1
and 4, inclusive.
SYMBOLS Optional. User-defined symbols that identify
map locations. If SYMBOLS is omitted from
the request, map symbols aren’t displayed.
For more information, see “SYMBOLS
Parameter,” on page 20. A list of comma-sepa-
rated items that desig-
nate map locations.
PPIY Optional. An integer that represents the cli-
ent browser’s vertical display resolution,
expressed in pixels per inch. If PPIY is omit-
ted from the request, Autodesk MapGuide
LiteView uses the default value 72 (the stan-
dard resolution for onscreen Web images).
For more information, see “PPIY Parameter,”
on page 19. An integer between 1
and 2147483647,
inclusive.
