imagestring()中的$size变量代指的就是字体大小 这个方法内置的字号只有1/2/3/4/5五种你可以使用imagettftext()函数代替 用法如下: array imagettftext ( resource image, float size, float angle, int x, int y, int color, string fontfile, string text ) float size代表字号,根据 GD 版本不同,应该以像素大小指定(GD1)或点大小(GD2)。 具体可以参照如下示例: <?php // Set the content-type header("Content-type: image/png");// Create the image $im = imagecreatetruecolor(400, 30);// Create some colors $white = imagecolorallocate($im, 255, 255, 255); $grey = imagecolorallocate($im, 128, 128, 128); $black = imagecolorallocate($im, 0, 0, 0); imagefilledrectangle($im, 0, 0, 399, 29, $white);// The text to draw $text = 'Testing...'; // Replace path by your own font path $font = 'arial.ttf';// Add some shadow to the text imagettftext($im, 20, 0, 11, 21, $grey, $font, $text);// Add the text imagettftext($im, 20, 0, 10, 20, $black, $font, $text);// Using imagepng() results in clearer text compared with imagejpeg() imagepng($im); imagedestroy($im); ?>
array imagettftext ( resource image, float size, float angle, int x, int y, int color, string fontfile, string text )
float size代表字号,根据 GD 版本不同,应该以像素大小指定(GD1)或点大小(GD2)。 具体可以参照如下示例:
<?php
// Set the content-type
header("Content-type: image/png");// Create the image
$im = imagecreatetruecolor(400, 30);// Create some colors
$white = imagecolorallocate($im, 255, 255, 255);
$grey = imagecolorallocate($im, 128, 128, 128);
$black = imagecolorallocate($im, 0, 0, 0);
imagefilledrectangle($im, 0, 0, 399, 29, $white);// The text to draw
$text = 'Testing...';
// Replace path by your own font path
$font = 'arial.ttf';// Add some shadow to the text
imagettftext($im, 20, 0, 11, 21, $grey, $font, $text);// Add the text
imagettftext($im, 20, 0, 10, 20, $black, $font, $text);// Using imagepng() results in clearer text compared with imagejpeg()
imagepng($im);
imagedestroy($im);
?>
