error while converting text to image using php

Question

// 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 = 'अन्ग्रेज़ी से हिन्दी'; // Replace path by your own font path $font = 'mangal.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); ?>

The output text is not same as the input text

I'm sure it's possible. Javascript is turing complete, so you can do anything. Now whether it's easy or efficient... and whether there are libraries available to do it... those are entirely different questions. — Jonathan Hall

What exactly are you trying to achieve? You could do this pretty trivially using the canvas element. — beatgammit

Yes, you can use <canvas> for that, see: https://developer.mozilla.org/en/Drawing_text_using_a_canvas

Not directly; javascript isn't supposed to be allowed to poke around in the guts of binary elements like images. You could render the text using a canvas element, or alternatively apply WebGL, but this is probably not what you want. If it absolutely has to be an image, the most portable way to do that is to make a web app that renders the text to an image and echos it back to a client. Using this, you can easily take a blob of text, create an image element that pulls the object back and then display that in the browser.

Ah, then you may be out of luck with using that method (through PHP anyway). I found the following question on localization and imagegettftext : stackoverflow.com/questions/2666105/missing-chars-in-jpgraph
