note 50779 added to ref.image

You get some trouble if you create an image by using the function imagettfbbox(). The x value is correct but the y value doesn't consider that a text can have more than one line. The second problem is to find the start position when you want to use imagettftext(), especially by using an angle > 90°. My solution uses some params to generate an image with any text. The image size is as small as possible, but you can add a margin without problems: params: $text > the string you want to write $format > output format "jpeg" or "png" $quality > jpeg quality, from 1 to 100 $font > font path and file $size > font size (px) $angle > angle of text in degrees $r > font color: red part $g > font color: green part $b > font color: blue part $bgr > background color: red part $bgg > bg color: green part $bgb > bg color: blue part $margin > a margin between text and border of pic code: <? if ($text != '') { list(,,$w) = imagettfbbox($size, 0, $font, $text); $lines = count(explode("\n", $text)); // get image size (not exactly) $angle_rad = $angle / 180 * pi(); $h = 2 * $size * $lines; $x = round($h * abs(sin($angle_rad)) + $w * abs(cos($angle_rad))) + $size; $y = round($h * abs(cos($angle_rad)) + $w * abs(sin($angle_rad))) + $size; // get start point for text $run_y = - $lines * $size + 1.5 * $size; $s_x = round($x / 2 - ($w / 2) * cos($angle_rad) + $run_y * sin($angle_rad)); $s_y = round($y / 2 + ($w / 2) * sin($angle_rad) + $run_y * cos($angle_rad)); // create image $im = imagecreatetruecolor($x, $y); @imageantialias($im, true); $bg = imagecolorallocate ($im, $bgr, $bgg, $bgb); $tx = imagecolorallocate ($im, $r, $g, $b); #imagecolortransparent ($im, $bg); imagefill($im, 0, 0, $bg); // put text imagettftext ($im, $size, $angle, $s_x, $s_y, $tx, $font, $text); // minimize borders // left for ($x = 0; $x < imagesx($im); $x++) { for ($y = 0; $y < imagesy($im); $y++) { if (imagecolorat($im, $x, $y) != $bg) break(2); } } $left = $x; // right for ($x = imagesx($im) - 1; $x >= 0; $x--) { for ($y = 0; $y < imagesy($im); $y++) { if (imagecolorat($im, $x, $y) != $bg) break(2); } } $right = $x; // top for ($y = 0; $y < imagesy($im); $y++) { for ($x = 0; $x < imagesx($im); $x++) { if (imagecolorat($im, $x, $y) != $bg) break(2); } } $top = $y; // bottom for ($y = imagesy($im) - 1; $y >= 0; $y--) { for ($x = 0; $x < imagesx($im); $x++) { if (imagecolorat($im, $x, $y) != $bg) break(2); } } $bottom = $y; // add margin $cut = imagecreatetruecolor($right - $left + 1 + $margin * 2, $bottom - $top + 1 + $margin * 2); $bg_ = imagecolorallocate ($cut, $bgr, $bgg, $bgb); imagefill($cut, 0, 0, $bg_); imagecopy ($cut, $im, $margin, $margin, $left, $top, $right - $left + 1, $bottom - $top + 1); // output if ($format == 'jpeg') { header("Content-type:image/jpeg"); imagejpeg($cut,false,$quality); } elseif ($format == 'png') { header("Content-type:image/png"); imagepng($cut); } } ?> you can download an interface soon: http://aka-fotos.de/scripts.php ---- Manual Page -- http://www.php.net/manual/en/ref.image.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+50779 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+50779&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+50779&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+50779&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+50779&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+50779&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+50779&report=yes Search -- http://master.php.net/manage/user-notes.php
