7.4.3.7 I, J
The mandatory I and J request parameters are integers that indicate a
point of interest on the map that was produced by the embedded GetMap
request (the “map request part” described in 7.4.3.3). The point (I,J) is
a point in the (i,j) space defined by the Map CS (see 6.7.2). Therefore:
⎯ the value of I shall be between 0 and the maximum value of the i
axis; ⎯ the value of J shall be between 0 and the maximum value of
the j axis; ⎯ the point I=0, J=0 indicates the pixel at the upper
left corner of the map; ⎯ I increases to the right and J increases
downward.
The point (I,J) represents the centre of the indicated pixel. If the value
of I or of J is invalid, the server shall issue a service exception (code
= InvalidPoint).
