[mapserver-users] Specify resolution (or pixel size) in WMS requests

[Rahkonen Jukka]

Hi,

Could you possible create a couple of images showing what is the current situation and how would you like the image to look like, together with corresponding parts of mapfile and requests you have used?

Hello,

we tried the parameter MAP.RESOLUTION AND MAP.DEFRESOLUTION with
MapServer 6.0.1 and made the following observations.

We tested with RESOLUTION=288&MAP.DEFRESOLUTION=72

The size of the symbols and textes was not like we expected. They were
often too small.

We tested with and without the parameter SYMBOLSCALEDENOM

1.) without SYMBOLSCALEDENOM (none scaled, fix size) ok are:

    * lines (not scaled) are dispayed correct (ok)
    * outlines (not scaled) of polygones are dispayed correct (ok).
    * symbols (not scaled) are displayed correct (ok).
    * textes (not scaled) are displayed correct (ok).We tested not scaled
texts without SYMBOLSCALEDENOM: It's displayed different weather
MINSIZE/MAXSIZE is existing or not.


2.) with SYMBOLSCALEDENOM

NOT ok:

    * Scaled symbols are displayed incorrect - too small.
    * Scaled lines are dispayed incorrect - too small.
    * scaled outlines of polygones are dispayed incorrect.
    * Scaled text are dispayed incorrect - too small.

For us it would be good to get this problem solved, as at the moment we
generate a copy of the mapfile for the print with symbol- and labelsize
multiplyed with factor 4. It would be charming to solve the print with one
mapfile. We could do testing and maybe I could look for sponsoring too.

Is there someone else interested to solve this? Is there a ticket already?
