TC,
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.
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.
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.
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.
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.
The operator can put in those labels manually, but the whole point was to
automate the process...
Sincerely,
Ken

looks like it *is* happening for your highway symbol (which is drawn first)..
The problem is that the next label (the "I-35" text) on the vertical line is
drawn to avoid the one that is already on the line. No way to stop that I
think...
do you always have both sets of labels drawing?

Hi,
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.
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.
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?
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.
Any magic we can invoke to do *that*????
Sincerely,
Ken
