GD Library imagettftext在Gujarati语言文本中遇到问题

Question

我用GD库创建了"Text on Image".我面临一个问题,即传递一些古吉拉特语文本,但输出错误如下:

我想要这样

得到:

我的代码是:

        $textBox = imagettfbbox($fontSize, $angle, $font, $txt);

        $textWidth = abs(max($textBox[2], $textBox[5]));

        $textHeight = abs(max($textBox[5], $textBox[7]));

        $x = (imagesx($this->img) - $textWidth)/2;

        $y = ((imagesy($this->img) + $textHeight)/$h)-($lines-2)*$textHeight;

        $lines = $lines-1;

        // Added this line from SO answer.
        $txt = mb_convert_encoding($txt, "HTML-ENTITIES", "UTF-8");
        $txt = preg_replace('~^(&([a-zA-Z0-9]);)~', htmlentities('${1}'), $txt);

        //add some shadow to the text
        imagettftext($this->img, $fontSize, $angle, $x + 2, $y + 1, $white, $font, $txt);

        //add the text
        imagettftext($this->img, $fontSize, $angle, $x, $y, $maroon, $font, $txt);

我已经在上面的代码中尝试了这个答案,但没有奏效.

有人可以帮我吗？

我已经为您给定的文本创建了示例示例，我使用了其他字体。您需要匹配字符映射才能显示正确的文本：

<?php
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 = 'xF]EZF+L';
// Replace path by your own font path
$font = __DIR__ . '/LMG-Arun.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);

您可以添加您的字体和样式。对于字符映射，请访问以下网址： https: //fonts.webtoolhub.com/font-n48283-lmg-arun.aspx
