Description

This script is a means to convert a string of text into an image. This has some simple uses such as displaying text such as email address that cannot be programmatically found. This can help to reduce the possibility of your email address being picked up by web crawlers and used for junk mail.

How To Use

To use the example interface above, simply modify or insert the string of text. You can edit any of the other settings, but this is optional.

The PHP Script

<? /* text to image converter daftlogic www.daftlogic.com */ Header("Content-type: image/png"); class textPNG { var $font = 'fonts/TIMES.TTF'; //default font. directory relative to script directory. var $msg = "no text"; // default text to display. var $size = 24; // default font size. var $rot = 0; // rotation in degrees. var $pad = 0; // padding. var $transparent = 1; // transparency set to on. var $red = 0; // black text... var $grn = 0; var $blu = 0; var $bg_red = 255; // on white background. var $bg_grn = 255; var $bg_blu = 255; function draw() { $width = 0; $height = 0; $offset_x = 0; $offset_y = 0; $bounds = array(); $image = ""; // get the font height. $bounds = ImageTTFBBox($this->size, $this->rot, $this->font, "W"); if ($this->rot < 0) { $font_height = abs($bounds[7]-$bounds[1]); } else if ($this->rot > 0) { $font_height = abs($bounds[1]-$bounds[7]); } else { $font_height = abs($bounds[7]-$bounds[1]); } // determine bounding box. $bounds = ImageTTFBBox($this->size, $this->rot, $this->font, $this->msg); if ($this->rot < 0) { $width = abs($bounds[4]-$bounds[0]); $height = abs($bounds[3]-$bounds[7]); $offset_y = $font_height; $offset_x = 0; } else if ($this->rot > 0) { $width = abs($bounds[2]-$bounds[6]); $height = abs($bounds[1]-$bounds[5]); $offset_y = abs($bounds[7]-$bounds[5])+$font_height; $offset_x = abs($bounds[0]-$bounds[6]); } else { $width = abs($bounds[4]-$bounds[6]); $height = abs($bounds[7]-$bounds[1]); $offset_y = $font_height;; $offset_x = 0; } $image = imagecreate($width+($this->pad*2)+1,$height+($this->pad*2)+1); $background = ImageColorAllocate($image, $this->bg_red, $this->bg_grn, $this->bg_blu); $foreground = ImageColorAllocate($image, $this->red, $this->grn, $this->blu); if ($this->transparent) ImageColorTransparent($image, $background); ImageInterlace($image, false); // render the image ImageTTFText($image, $this->size, $this->rot, $offset_x+$this->pad, $offset_y+$this->pad, $foreground, $this->font, $this->msg); // output PNG object. imagePNG($image); } } $text = new textPNG; if (isset($msg)) $text->msg = $msg; // text to display if (isset($font)) $text->font = $font; // font to use (include directory if needed). if (isset($size)) $text->size = $size; // size in points if (isset($rot)) $text->rot = $rot; // rotation if (isset($pad)) $text->pad = $pad; // padding in pixels around text. if (isset($red)) $text->red = $red; // text color if (isset($grn)) $text->grn = $grn; // .. if (isset($blu)) $text->blu = $blu; // .. if (isset($bg_red)) $text->bg_red = $bg_red; // background color. if (isset($bg_grn)) $text->bg_grn = $bg_grn; // .. if (isset($bg_blu)) $text->bg_blu = $bg_blu; // .. if (isset($tr)) $text->transparent = $tr; // transparency flag (boolean). $text->draw(); // GO!!!!! ?>

Further Help

For anyone finding problems using this...

(1) Please test this example to ensure imagecreate works on your server...

<?php
header("Content-type: image/png");
$im = @imagecreate(110, 20)
or die("Cannot Initialize new GD image stream");
$background_color = imagecolorallocate($im, 0, 0, 0);
$text_color = imagecolorallocate($im, 233, 14, 91);
imagestring($im, 1, 5, 5, "A Simple Text String", $text_color);
imagepng($im);
imagedestroy($im);
?>

(2) Make sure to use the example at the top of this page by sending POST variables from your form. For example msg,font,size ...

 By hi on 16/08/2011

The text looks very poor quality. Is there some anti-aliasing effect you could put on it?

Could you also add multi-line with justification alignment.

Change the form so the input comes from a textarea instead of from an input element. :D I put in text with line breaks, it was only 3 lines long but, the script put out the expected result. :D

Nice. :D

 By chaunh on 28/07/2010

To make it work without the form, you need to change the 'isset lines' to this form:

if (isset($_GET['msg'])) $text->msg = $_GET['msg']; // text to display

 By Bekaar Hai on 02/07/2010

The displayed PNG is quite ugly, and this script needs to be changed to display aliased fonts, to clean up the jagged edges.

it is working in localhost but not in server 
 By subhas on 23/09/2009

this doesn't work.  all i changed in the script was "default font. directory relative to script directory." to my fonts path directory and added the PHP  to the front/end of the script and it doesn't work.  when i run the script i keep getting the default text converted to image "no text".  if i type new text in the form fields or change any of the values none of that is changed in the image.  its always the "no text" image that comes up.
