I'm trying to work through Tutorial4.0 with MapServer 4.0 on Windows 2000.
I made the needed changes to the path information in the html and map
files. Everything works fine for Examples 1.1, 1.2, and 1.3, but from 1.4
on the image does not display. What's different beginning with example
1.4?

<hr align="center" width="300">
<p>Here we introduce a few more parameters along with the LABEL
object:</p>
<p>FONTSET<br>
Here we specify the full path to our truetype fonts list (or font
set)
file. This file lists each of the available fonts. See the file
itself
and the <a
href="http://mapserver.gis.umn.edu/doc40/fontset.html">MapServer
fonset documentation</a> for more info. FONTSET is a parameter of
the
MAP object.</p>
<p>LABELITEM<br>
This specifies which data attribute to use for labeling, in this
case
"STATE". LABELITEM is a parameter of the LAYER
object.</p>
<p>LABEL<br>
Marks the beginning of the LABEL object. The label object can be
used
under other objects (i.e. the SCALEBAR object).</p>
<p> COLOR<br>
Within the LABEL object, COLOR specifies the color of the label
text.</p>
<p>SHADOWCOLOR<br>
This specifies the shadow color of the label text.</p>
<p>SHADOWSIZE<br>
Specifies the shadow size. The value corresponds to the X and the
Y shifts
in pixels. So, "2 2" means two pixels wide by two pixels
high.</p>
<p>TYPE<br>
Within the LABEL object, TYPE specifies what type of font to use.
We have
the choice of TRUETYPE or BITMAP (the built-in fonts). We choose
TRUETYPE.</p>
<p>FONT<br>
If you specify TYPE as TRUETYPE, you need to specify what font to
use.
The value here is the "alias" in the font list file.</p>
<p>SIZE<br>
If using truetype fonts, the value is size in pixels. If bitmap,
you can
say something like "small" or "large".</p>
<p>ANTIALIAS<br>
This turns truetype antialiasing on or off. Remember the value
isn't on
or off but TRUE or FALSE.</p>
<p>POSITION<br>
Where to position the label text in relation to the label points.
The
value is a combination of vertical and horizontal positions. You
have
the following choices for vertical alignment: C for center, U for
upper,
and L for lower. For horizontal alignment you have the following
choices:
C for center, L for left, and R for right. So, to align the label
text
to the center of label ID you'd use the value "CC"
(center-center).
Or if you'd like it to be on the lower left of the ID, you'd use
LL. Another
way is to let MapServer decide the best position for your labels.
For
this you would use the value "AUTO".</p>
<p>PARTIALS<br>
Tells MapServer whether to generate incomplete label texts or not.
The
default here is not to generate fragments of a label text. The
value is
either TRUE or FALSE.</p>
<p>MINDISTANCE<br>
This is the minimum distance in pixels between duplicate labels.
See what
happens if you increase or decrease this value.</p>
<p>BUFFER<br>
The padding (in pixels) for each label. This is used to enhance
readability.
A BUFFER of 4 pixels mean that no label will be drawn within four
pixels
of each other. Again, change to see how it works.<br>
</p>
<hr align="center" width="300">
<p>You can also create labels separate from a POLYGON layer. You do
this
with the ANNOTATION data type. Have a look at the file
"example1-4a.map"
to see how you'd implement this kind of labeling. You will notice
that
the CLASS object within the "label" layer has a COLOR
parameter
value of "-1 -1 -1". The negative number tells MapServer
to
give this CLASS a transparent color (the label IDs don't show up).
Once
again, play with the values to understand how it affects the
map.</p>
