<DIV><FONT face=Arial>TC,</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Yes, I don't have any control over that.
Yet. The I-35 symbol and text are not issues, in this case, because
they are closer to the center of the picture.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>My center coordinates are selected from a list of land
survey plots... in the north central US, the land was surveyed in plots of 1
square mile -- 640 acres. The bulk of the individual fields in which I am
interested (like 99.1%) will fall within the boundaries of that square mile, or
section, to use the survey word.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>However, the maps we create are used for navigating to the
"correct" field by field crews, and we have found that the operator in the
office that creates them is much happier (and more accurate) if they can see a
margin around that section for context & landmarks. We try to have
approximately 1/2 mile all the way around. </FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>This operator draws in boundaries (using software I've
written for the purpose) to mark the fields of interest, some of which extend
past the edge of the section. Then, so as to have a larger picture in the
field, the picture is cropped some to get rid of some of the
border.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Unfortunately, some of the roads begin at the section
boundary and extend toward the edge of the picture, and those labels are then
placed somewhere between the edge of the section and the edge of the picture,
and these may end up missing from the final product.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>The operator can put in those labels manually, but the
whole point was to automate the process...</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>

<DIV><BR> Hi,</DIV>
<DIV> </DIV>
<DIV> I'm using a program generated query to fetch
a transparent PNG file of about 1600 pixels square from a streets & roads
database in Iowa. A sample URL is pasted below my sig lines.</DIV>
<DIV> </DIV>
<DIV> It works great, but the problem is that the
features from a different layer (aerial photo) in which I am interested will
usually be within the center 1/4 of the picture, and it usually gets cropped to
center on that feature, which blows away some of my labels.</DIV>
<DIV> </DIV>
<DIV> Is there any way to force the labels closer
to the (x,y) center of the returned PNG file while still following along
whatever feature they are identifying?</DIV>
<DIV> </DIV>
<DIV> That is to say, if there is one on a
north/south road, we'd like it to be nearer the Y center of the pic, and if one
is on an east/west road, then have it be closer to the X center of the
picture.</DIV>
<DIV> </DIV>
<DIV> Any magic we can invoke to do
*that*????</DIV>
<DIV> </DIV>
