[Mapserver-users] Edges of Images

[Matthew Haines]

Why not make some copies of the column 1 tiles and label them as column n+1?
(where n is the width of the image)

Thanks Ed. Thats not quite what I meant though. This person has asked if
is there some magical way for mapserver to show the left side of the B1
image when I'm zoomed in over the right side of the B4 image. The B1
tile is georeferenced to have a minx of -180 and the B2 tile is
georeferenced to have a maxx of +180 so in the real world these two
edges should meet. Instead a white area is displayed anywhere right of
the +180

Benjamin -

Set the map image background to white and then use the OFFSITE 255 255
255 statement in the data layer to make all white pixels transparent
(assuming the no-data value really is exactly that value).  This will
cause areas of white that overlap another tile to disappear, and any
valid data pixels that are white will expose the white background and
show up as white.

Hi,

I'm currently using 8 satalite image tiles of the world (referenced in
lat/longs) in Mapserver as shown below:


--------------------------
A1 | A2 | A3 | A4 |
--------------------------
B1 | B2 | B3 | B4 |
--------------------------

If I zoom into the lower right tile (B4) I can see a large white band
running top to bottom where the tile finishes just right of New Zealand.
Someone has asked me if it's possible for Mapserver to automatically
display the next logical tile (which would be B1) to stop the ugly white
band. Any ideas?

Cheers,

Benjamin Wragg
