I have the following issue: I am making a "gas guage" based on a percentage. ie. - a 180 degree arc is created - the range will be 0 to n (undetermined ammount) - there will be x number of entries - the needle will pount to a a percentage for (int)floor((x / n) * 100)
The issue is, I have the starting pt for the needle (imagefilledarc needs the center of the 'circle' as the starting pt, which is where the needle will start too), but how would I get the x|y coordinates for the end of the needle based on a perentage of a half-circle (180 degree arc)? Appreciate any clues or ideas. --- Michael Geier -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
