I'm sorry I haven't been terribly attentive, but I've been sidetracked more than a few times by school and other things in the last few weeks.
Sort answer: Pixels are pixels
. You can't have anything but a whole-number of pixels because a display can't show half of one for example. The measurements you've been giving me are likely in cm or inches or something, which i can't work with easily.
The map of the city I've provided has dimensions:
width:2436px
height:2467px
The coordinates i need have to be in pixels in this order:
pixels away from the left-hand side of the image
pixels away from the top of the image.
In other words, for a point to go at the very top-left of the page, the coords should be 0,0. the bottom-right would be 2436,2467. Dead centre would be 1218,1234 (note that you can't have half a pixel so you have to round up or down).
I don't use photoshop or paint shop pro, but I'm positive there is a way you can get it to tell you those coordinates, although they might give them in a different order. some experimenting might be in order.
Also, just out of curiosity, if you could provide me with the coordinates of the centre of the exhibition track the same way you did before, i might be able to figure out how the program you're using is calculating things.
