And what exactly? You need to explain better. You can get coordinates in a number of ways from simply hovering with the mouse with the tools and checking the info palette to the analysis tools, but it's really not clear what exactly you need or for that matter what "polygon image" is supposed to mean.
I want to create a complicated polygonal hotspot around the map of many countries of the world in Dreamweaver (eg. a hotspot around the US border), but don't want to spend the time tediously selecting the coordinates around the border.
i.e. the code in Dreamweaver would be something like this
<area shape="poly" coords="5,343,18,340,38,327,71,314,88,304,75,302,63,301,46,301,58,290,58,284,40,292,36,28 1,43,276,47,263,62,257,91,244,99,244,113,237,132,235,146,226,155,222,131,221,102,223,106,2 06,151,197,153,202,164,203,178,198,187,198,181,189,176,187,170,173,185,166,209,162,229,154 ,253,146,280,143,307,142,321,136,354,143,374,145,404,150,429,149,440,155,314,259,304,268,2 94,276,302,281,310,278,308,288,311,296,328,292,338,284,342,290,340,296,341,310,335,325,342 ,335,346,341,342,345,333,351,327,357,321,343,324,340,316,323,321,318,318,306,307,307,298,2 87,274,282,252,280,238,272,236,268,212,273,209,283,164,294,187,274,132,295,128,301,32,338, 18,346" href="/UnitedStates.html"
Is there a way to use Photoshop's magic wand tool / slice / path tool to extract the coordinates of an images border for me?
From my understanding, unfortunately slices can only be rectangular, not polygonal.
When I went to school I was told a rectangle was a four sided polygon.... Use a PNG.....
Looks like we have a wise guy over here!
To clarify - from what I know, slices can only be rectangular, i.e. a 4-sided shape comprising of four 90 degree angles.
Then there is http://tidesonline.nos.noaa.gov/maps.html
So the second one has what you want do not know how they did it ......
I'm pretty sure you can access control point coordinates via scripting.
