There are BC issues with FT1 support in gd. The code requires deep changes to solve this issue. pierre Previous Comments: ------------------------------------------------------------------------ [2003-07-20 03:29:03] kyle at putnamcabinets dot com I've upgraded to PHP 4.3.3RC1 and the problem still exists. Maybe a problem with GD? I've reported the bug to boutell.com and haven't recieved a response in over three weeks. An exmple of this bug at work (problem with imagettfbbox and imagettftext): http://webdev.quiteuseless.com/damn-gd-ttf-bugs/test.php ------------------------------------------------------------------------ [2003-06-24 01:33:35] kyle at putnamcabinets dot com I also experience the problem with PHP 4.3.2 and bundled GD version '2.0.12 compatible'. Recompiled with Debian package version (2.0.12-2... damn!) and same problem (obviously). It seems to be some how proportional to the angle of the text; smaller angles yield more accuracy. My implementation: <? $res = imagecreatetruecolor(400, 400); $white = imagecolorallocate($res, 0xff, 0xff, 0xff); $red = imagecolorallocate($res, 0xcc, 0x00, 0x00); $blue = imagecolorallocate($res, 0x00, 0x00, 0xcc); imagefill($res, 0, 0, $white); for ($angle = 0; $angle < 360; $angle += 60) { $wrong1 = imagettftext($res,20,$angle,200,200,$blue, "/usr/share/fonts/truetype/Courier_New.ttf", "ABCDEF 12345"); $t = imagettfbbox(20, $angle, "/usr/share/fonts/truetype/Courier_New.ttf", "ABCDEF 12345"); $wrong2 = array(200+$t[0],200+$t[1],200+$t[2], 200+$t[3],200+$t[4],200+$t[5],200+$t[6],200+$t[7]); imagepolygon($res,$wrong2,count($wrong2)/2,$red); imagepolygon($res,$wrong1,count($wrong1)/2,$red); } header("Content-type: image/png"); imagepng($res); ?> ------------------------------------------------------------------------ [2003-06-18 03:03:12] guno at guno dot nl I'm experiencing the same problem, using php 4.3.2 with GD 2.0.15 Normal text (with no rotation) results in a correct bounding box, but as soon as I rotate the text, it goes wrong, no matter which font I use. Here's a sample code which displays a text with it's bounding box at 0, 90, 180 and 170 degrees: <?php $image=imagecreate(500, 500); $imagedum=imagecreate(500, 500); $color1=imagecolorallocate($image, 0xff, 0xff, 0xff); $color2=imagecolorallocate($image, 0x3f, 0x3f, 0x3f); $color3=imagecolorallocate($image, 0xff, 0x00, 0x00); for ($angle=0; $angle<360; $angle+=90) { $text="ABCpqrs"; $font = "./verdana.ttf"; // Draw the text into the image: $result=imagettftext($imagedum, 30, $angle, 250, 250, $color2, $font, $text); imagettftext($image, 30, $angle, 250, 250, $color2, $font, $text); // Draw the bounding-box into the image: imageline($image, $result[0], $result[1], $result[2], $result[3], $color3); imageline($image, $result[2], $result[3], $result[4], $result[5], $color3); imageline($image, $result[4], $result[5], $result[6], $result[7], $color3); imageline($image, $result[6], $result[7], $result[0], $result[1], $color3); } // Draw the image to the screen: header("Content-Type: image/jpeg"); imagejpeg($image); imagedestroy($image); imagedestroy($imagedum); ?> ------------------------------------------------------------------------ [2003-05-16 19:37:07] ljpersson at hotmail dot com Just checked with 4.3.2RC3 and the problem still exists. ------------------------------------------------------------------------ [2003-05-05 13:23:02] ljpersson at hotmail dot com This problem still exists in 4.3.2RC2. This returns yet another set of (wrong) coordinates for the bounding box. With 4.3.2RC2 (Compiled on SuSE 8.2) gives the following wrong return array: Array ( [0] => -1 [1] => 14 [2] => -1 [3] => -146 [4] => -17 [5] => -146 [6] => -17 [7] => 14 ) Which is again different from what was returned in 4.3.1 ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
