imagecharup

(PHP 4, PHP 5, PHP 7)

imagecharup — 垂直地画一个字符

说明

bool imagecharup ( resource $image , int $font , int $x , int $y , string $c , int $color )

imagecharup() 将字符 c 垂直地画在 image 指定的图像上，位于 x，y（图像左上角为 0, 0），颜色为 color。如果 font 为 1，2，3，4 或 5，则使用内置的字体。

Example #1 imagecharup() 例子


<?php

$im = imagecreate(100,100);

$string = 'Note that the first letter is a N';

$bg = imagecolorallocate($im, 255, 255, 255);
$black = imagecolorallocate($im, 0, 0, 0);

// prints a black "Z" on a white background
imagecharup($im, 3, 10, 10, $string, $black);

header('Content-type: image/png');
imagepng($im);

?>

I'm using imagestringup() function to write text upwards.

php at corzoogle dot com 17-Jun-2005 01:28


<?php

// incredibly, no one has added this.

// write a string of text vertically on an image..

// ;o)



$string = '(c) corz.org';

$font_size = 2;

$img = imagecreate(20,90);

$bg = imagecolorallocate($img,225,225,225);

$black = imagecolorallocate($img,0,0,0);



$len = strlen($string);

for ($i=1; $i<=$len; $i++) {

    imagecharup($img, $font_size, 5, imagesy($img)-($i*imagefontwidth($font_size)), $string, $black);

    $string = substr($string,1);

}

header('Content-type: image/png');

imagepng($img);

imagedestroy($img); // dudes! don't forget this!

?>
