<DIV><FONT face=Arial size=2>Thanx Flavio to reopen a subject that I
investigated more than 1 year ago and pushed me to re-check the situation
with newer relases of Mapserver and GDAL.</FONT></DIV>
<DIV><FONT face=Arial size=2>Though the Jpeg outputformat is much lighter than
the Png24 I experienced a problem with truetype point symbols. I
don't know why but with the jpeg outputformat they are shown in a very poor
quality. Instead using the same mapfile, just changing the outputformat to
Png24, the truetype symbols are perfect. The Jpeg quality doesn't influence this
behaviour, even if i set it to 100 it's the same. </FONT></DIV>
<DIV><FONT face=Arial size=2>So if I want perfect symbols I have to set the
outputformat to png24 but in this way the file is much bigger. Otherwise I have
to renounce the truetype symbols and use only the other types of point symbols.
Is this a limitation of the Gdal libraries?</FONT></DIV>
<DIV><FONT face=Arial size=2>For what regards the line antialiasing I noticed,
though not measuring it, that the performance is strongly affected by the use of
a cartoline line symbol even if the outputformat is set to Jpeg.</FONT></DIV>
<DIV><FONT face=Arial size=2>The antialiasing is an interesting feature and
the desktop systems (ex. Manifold) that uses a good antialiasing engine
really have a very attractive look but, depending of the project goals,
this feature could be considered of secondary importance compared to
performance, especially in case or many remote accesses and not so fast
connections such as in my country.</FONT></DIV>
