Bug #11917 Updated: imageDashedLine() only seems to draw vertical lines

ID: 11917 Updated by: derick Reported By: kyhm@kyhm.com Old-Status: Open Status: Closed Bug Type: Documentation problem Operating system: PHP Version: 4.0.6 Assigned To: Comments: Not a PHP bug, so closing Previous Comments: --------------------------------------------------------------------------- [2001-07-06 07:44:58] wez@php.net It's a GD problem. GD 2.0.1 is still BETA. --Wez. --------------------------------------------------------------------------- [2001-07-06 04:53:10] kyhm@kyhm.com Thanks for the prompt response, and I agree entirely about persistence of functions! Since I've now seen the deprecation notice under imageDashedLine() and know what to change in my code, should I marked this as closed? --------------------------------------------------------------------------- [2001-07-06 03:45:16] derick@php.net I made this a documentation problem, because it's not really a bug in PHP. derick --------------------------------------------------------------------------- [2001-07-06 03:44:19] derick@php.net I complained about this too, a while ago (bug 11663). The way it works in 4.0.6 is using imagesetstyle with imageline, this is in new documentation at imagedashedline. However, IMHO: <<steam>> A function should not suddenly stop working. It either should be dropped, or should continue to work as before. At least not between minor releases. At least not without _any_ warnings in release notes. (A mention about GD library version change is not enough) _any_ warnings in release notes. (A mention about GD library version change is not enough) <</steam>> I worked around it with this (my client still has 4.0.5, I upgraded to 4.0.6): function MDashedLine($image, $x0, $y0, $x1, $y1, $fg, $bg) { if (PHP_VERSION == "4.0.5") { ImageDashedLine($image, $x0, $y0, $x1, $y1, $fg); } else { $st = array($fg, $fg, $fg, $fg, $bg, $bg, $bg, $bg); ImageSetStyle($image, $st); ImageLine($image, $x0, $y0, $x1, $y1, IMG_COLOR_STYLED); } } // MDashedLine --------------------------------------------------------------------------- [2001-07-05 20:05:36] kyhm@kyhm.com Using PHP 4.0.6, GD 2.0.1, Apache 1.3.19, and a TrueColor image, this code: $img = imageCreateTrueColor (64, 64); $wht = imageColorAllocate ($img, 255, 255, 255); imageFill ($img, 0, 0, $wht); $red = imageColorAllocate ($img, 255, 0, 0); $x1 = 16; $y1 = 16; $x2 = 48; $y2 = 48; imageDashedLine ($img, $x1, $y1, $x1, $y2, $red); imageDashedLine ($img, $x1, $y1, $x2, $y2, $red); imageDashedLine ($img, $x1, $y1, $x2, $y1, $red); imageDashedLine ($img, $x2, $y2, $x1, $y2, $red); imageDashedLine ($img, $x1, $y2, $x2, $y1, $red); imageDashedLine ($img, $x2, $y1, $x2, $y2, $red); header ("Content-type: image/png"); imagePNG ($img); Should produce a red square with diagonal lines.
