convert text to image in php [duplicate]

Question

I would like to style a text string taken from a form field and then convert it to a transparent .PNG (alpha BG).

Is this possible with PHP? If so, would you kindly show me how this would be achieved

Answer 1

yes, its very much possible, you are going to follow the same technique as we do while generating a captcha image.

Requirement: GD library should be enabled in your php.

Code (taken from php help file ;)

<?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); ?>  

Answer 2

convert text to image (php code):

at first, you need to ensure, that the hosting has enabled GD library (in a new php file, execute phpinfo(); and in output see/find if GD library is enabled) .

Solution 1 (auto-sized output):

TextToImage_my( $text='Helloooo! my unicode words:  ǩ Ƥ Ў  ض ط  Ⴓ ');     // ==== other parameters can be used too, see the function arguments below 

function code: text-to-image.php

Solution 2 (manual-sized output):

(needs to have manual width&height of output, longer strings are cut out)..

<?php $text = "YOUR  texttttttttttttttt";  $my_img = imagecreate( 200, 80 );                             //width & height $background  = imagecolorallocate( $my_img, 0,   0,   255 ); $text_colour = imagecolorallocate( $my_img, 255, 255, 0 ); $line_colour = imagecolorallocate( $my_img, 128, 255, 0 ); imagestring( $my_img, 4, 30, 25, $text, $text_colour ); imagesetthickness ( $my_img, 5 ); imageline( $my_img, 30, 45, 165, 45, $line_colour );  header( "Content-type: image/png" ); imagepng( $my_img ); imagecolordeallocate( $line_color ); imagecolordeallocate( $text_color ); imagecolordeallocate( $background ); imagedestroy( $my_img ); ?>
