note 117432 added to function.imagerectangle

Please pay attention if you want to draw pixel perfect rectangles: Since this function uses absolute values for the second coordinate points (instead of width and height), you might face a logical problem. PHP counts from 0. But a pixel at position 0,0 occupies already a 1x1 space. In the example above you have the following line: imagerectangle($canvas, 50, 50, 150, 150, $pink); If you don't pay attention, you might thing that the difference between the two coordinates is exactly 100 and assume that the drawn rectangle would have the dimension of 100 x 100 pixels too. But it would be 101 x 101, because PHP counts from 0 and imagerectangle() uses absolute coordinates for the second point too. A smaller example: A rectangle with coordinates 0,0 and 5,5 means 0,1,2,3,4,5 which are 6 pixels, not 5. ---- Server IP: 72.52.91.14 Probable Submitter: 85.177.89.127 ---- Manual Page -- http://php.net/manual/en/function.imagerectangle.php Edit -- https://master.php.net/note/edit/117432 Del: integrated -- https://master.php.net/note/delete/117432/integrated Del: useless -- https://master.php.net/note/delete/117432/useless Del: bad code -- https://master.php.net/note/delete/117432/bad+code Del: spam -- https://master.php.net/note/delete/117432/spam Del: non-english -- https://master.php.net/note/delete/117432/non-english Del: in docs -- https://master.php.net/note/delete/117432/in+docs Del: other reasons-- https://master.php.net/note/delete/117432 Reject -- https://master.php.net/note/reject/117432 Search -- https://master.php.net/manage/user-notes.php
