将阿拉伯语文本导出为图像 [英] export arabic text as images

问题描述

我在UTF-8中有一堆阿拉伯文字。我试图显示此设备的设备不支持显示的阿拉伯语文本。因此，我需要将文本转换为图像。

I have a bunch of lines of Arabic text in UTF-8. The device I am trying to display this one does not support arabic text being displayed. Therefore, I need to convert the text into images.

我想将每行文本保存为具有特定宽度的图像。我也需要使用特定的字体。做这个的最好方式是什么？有没有人知道这里有用的工具？

I would like to save each line of text as an image with a specific width. I need to use a specific font as well. What is the best way to do this? Does anybody know of a tool that can be helpful here?

到目前为止我遇到的问题：

Problems I've run into so far:

PHP + GD：阿拉伯字母看起来是分开的，不应该像草书一样。
VB.net：我可以将每行文本转储到richtextbox中......但我不知道如何导出该控件的图像。
Flash：不支持从右到左文本。

PHP + GD: Arabic letters appear seperated and not in cursive as they should. VB.net: I can dump each line of text into a richtextbox... but I don't know how to export the image of just that control. Flash: no support for right to left text.

推荐答案

至于阿拉伯语，你需要一个库来反向字符/字形 PHP / GD 。见例如 http://sourceforge.net/projects/ar-php/ 或 http://www.ar-php.org/ 。

As for Arabic, you need a library to reverse chars/glyphs for PHP/GD. see e.g. http://sourceforge.net/projects/ar-php/ or at http://www.ar-php.org/.

确保 PHP文件编码 unicode / UTF 。

eg >打开记事本>另存为>编码为UTF-8：

Make sure your PHP file encoding is in unicode/UTF.
e.g. > open Notepad > Save As > encoding as UTF-8:

使用 imagettftext 的PHP中阿拉伯字体排版的示例用法：

Sample usage for Arabic typography in PHP using imagettftext:

<?php 
    // The text to draw
    require('./I18N/Arabic.php'); 
    $Arabic = new I18N_Arabic('Glyphs'); 
    $font = './DroidNaskh-Bold.ttf';
    $text = $Arabic->utf8Glyphs('لغةٌ عربيّة');

    // Create the image
    $im = imagecreatetruecolor(600, 300);

    // 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, 599, 299, $white);

    // Add the text
    imagettftext($im, 50, 0, 90, 90, $black, $font, $text);

    // Using imagepng() results in clearer text compared with imagejpeg()
    imagepng($im, "./output_arabic_image.png");
    echo 'open: ./output_arabic_image.png';
    imagedestroy($im); 
?>
