GD Library imagettftext getting problem in Gujarati Language Text

Question

I have used GD Library to create "Text on Image". I am facing one issue that passing some Gujarati text but getting wrong output as below:

I want like this

and getting:

My code is:

        $textBox = imagettfbbox($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);

I have already tried this answer in above code but didn't worked.

Can anyone help me please?

Answer 1

I have created sample example for your given text, I have used other font. You need to match the character mapping to display the correct the text:

<?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);

You can add your font and style. For the character mapping follow the url: https://fonts.webtoolhub.com/font-n48283-lmg-arun.aspx
