Hello;

For some reason when I classify polygons, the class symbol in the legend has
an extra pixel located in the bottom right-hand side of the symbol/image
(see attached file).  When I set the Class's Outline colour, the extra pixel
does not appear.  I am using the HTML legend.

Does anyone know why this occurs and how to get rid of it?

Thanks in advance.

Kurt,

Sorry I don't have an actual solution, but I find that I'm having the same
problem.  I find that I can zoom in on my dataset, but as soon as I pan or
zoom to full extent, the map goes blank.  I even lose the ROSA controls
sometimes.  I found that if I removed the INPUT_COORD=0%2C0%3B0%2C0 (which
is interpreted as INPUT_COORD=0,0;0,0) the map would load fine.  I'm not
sure if there's something missing from my mapfile, or if the PHP code
generated by GMapFactory has some kind of bug (I'm also using the latest
release).  Also, I didn't have this problem until I altered my mapfile with
new max extents, and started using my layers in PostGIS.

I hope someone can offer a better solution...

Mike

Subject: [maplab-users] Empty map frame when zooming in tutorial map

Hi,
I have successfully installed mapserver 3.6.5 with mapscript and maplab 
2.0release (final) on php 4.3.2rc2 on a debian woody.
To test my installation, I used the tutorial map from maplab.
When I load the mapfile in MapEdit, everything works fine. When I click on 
"preview map" the map shows up with no error.
But when I then try to redraw the map by zooming in, the map frame remains 
blank. The map doesn't show up again. 
Which setting is wrong? 

I have made the same request a month ago, and Paul Spencer gave me the
following answer: 

> There was a bug in the preview that caused the layer controls not to 
> show up.  When zooming, the page submits and layer visibility is 
> maintained by the layer controls (checkboxes). Because these never made 
> it into the page, all the layers get turned off.  Closing the preview 
> and reopening causes the map to be displayed again.  If these are your 
> symptoms, please grab the latest nightly build as we have fixed this

But, installing the newest version of maplab: 2.0 final, didn't help. 
So probably I'm doing something wrong.. but what?
