imagestring

(PHP 4, PHP 5)

imagestring — Draw a string horizontally

Description

bool imagestring ( resource $image , int $font , int $x , int $y , string $string , int $color )

Draws a string at the given coordinates.

Parameters

image: An image resource, returned by one of the image creation functions, such as imagecreatetruecolor().
font: Can be 1, 2, 3, 4, 5 for built-in fonts in latin2 encoding (where higher numbers corresponding to larger fonts) or any of your own font identifiers registered with imageloadfont().
x: x-coordinate of the upper left corner.
y: y-coordinate of the upper left corner.
string: The string to be written.
color: A color identifier created with imagecolorallocate().

Return Values

Returns TRUE on success or FALSE on failure.

Examples

Example #1 imagestring() example


<?php
// Create a 100*30 image
$im = imagecreate(100, 30);

// White background and blue text
$bg = imagecolorallocate($im, 255, 255, 255);
$textcolor = imagecolorallocate($im, 0, 0, 255);

// Write the string at the top left
imagestring($im, 5, 0, 0, 'Hello world!', $textcolor);

// Output the image
header('Content-type: image/png');

imagepng($im);
imagedestroy($im);
?>

The above example will output something similar to:


this is a function that is based on imagestring but it produces text in the center of an image i hope it helps :D





<?php


function ImageStringCenter($image_resource, $font_size, $line_number, $total_lines, $text, $color ) {





    $center_x = ceil( ( imagesx($image_resource) - ( ImageFontWidth($font_size) * strlen($text) ) ) / 2 );





    $center_y = ceil( ( ( imagesy($image_resource) - ( ImageFontHeight($font_size) * $total_lines ) ) / 2)  + ( ($line_number-1) * ImageFontHeight($font_size) ) );





ImageString($image_resource, $font_size, $center_x, $center_y, $text, $color );





}


?>

If you have any problem with CentralEurope's words, for example : ľščťžýáíéúäňôď, I am try this problem by iconv() function.



<?php

// create example image

$im = imagecreate(200, 20);

$bg = imagecolorallocate($im, 255, 255, 255);

$textcolor = imagecolorallocate($im, 0, 0, 255);

$text = "ľščťžýáíéúäňôď...";



//simple convert string

$string = iconv("Windows-1250", "Latin2", $text);



// write converted string at the top left

imagestring($im, 4, 0, 0, $string, $textcolor);



// output the image

header("Content-type: image/png");

imagepng($im);

?>

Creates a box of text. Has horizontal and vertical alignment, box arguments, and custom leading. I submitted this to the manual in 2003 actually, but it disappeared after a year or so (not sure why). Here it is again.



<?php

define("ALIGN_LEFT", "left");

define("ALIGN_CENTER", "center");

define("ALIGN_RIGHT", "right");

define("VALIGN_TOP", "top");

define("VALIGN_MIDDLE", "middle");

define("VALIGN_BOTTOM", "bottom");



function imagestringbox(&$image, $font, $left, $top, $right, $bottom, $align, $valign, $leading, $text, $color)

{

   // Get size of box

   $height = $bottom - $top;

   $width = $right - $left;

  

   // Break the text into lines, and into an array

   $lines = wordwrap($text, floor($width / imagefontwidth($font)), "\n", true);

   $lines = explode("\n", $lines);

  

   // Other important numbers

   $line_height = imagefontheight($font) + $leading;

   $line_count = floor($height / $line_height);

   $line_count = ($line_count > count($lines)) ? (count($lines)) : ($line_count);

  

   // Loop through lines

   for ($i = 0; $i < $line_count; $i++)

   {

       // Vertical Align

       switch($valign)

       {

           case VALIGN_TOP: // Top

               $y = $top + ($i * $line_height);

               break;

           case VALIGN_MIDDLE: // Middle

               $y = $top + (($height - ($line_count * $line_height)) / 2) + ($i * $line_height);

               break;

           case VALIGN_BOTTOM: // Bottom

               $y = ($top + $height) - ($line_count * $line_height) + ($i * $line_height);

               break;

           default:

               return false;

       }

      

       // Horizontal Align

       $line_width = strlen($lines[$i]) * imagefontwidth($font);

       switch($align)

       {

           case ALIGN_LEFT: // Left

               $x = $left;

               break;

           case ALIGN_CENTER: // Center

               $x = $left + (($width - $line_width) / 2);

               break;

           case ALIGN_RIGHT: // Right

               $x = $left + ($width - $line_width);

               break;

           default:

               return false;

       }

      

       // Draw

       imagestring($image, $font, $x, $y, $lines[$i], $color);

   }

  

   return true;

}

this code you can write the string within the url by a $_get function

I've taken the code of Epidemiah and improved the code so that the function now can handle generic position commands (as e.g. left / bottom) or int-values as left/top position of the text to write (with positive values used as left/top position and negative from right/bottom).



So e.g. imageWriteString($img, $font, $text, $color, -10,-10); writes the text so that there is 10 px space to right and bottom border of image.



Hope this is useful. Could be optimized and checked in detail, but works fine for me.

Simple script to convert a string (such as an email addresses) to a transparent image.



Usage: 

<img src="stringtoimg.php?string=<?= urlencode(base64_encode($email)) ?>">



From a spambot's point of view, they see:

<img src="stringtoimg.php?string=ZpbXZG92ZXJsb3JkQGdtYWlsLmNvbQ%3D%3D">



Optional parameters:

    font_size: 1 to 5, with the default at 3

    R/G/B: the font color, in hex.



Usage:

<img src="stringtoimg.php?string=<?= urlencode(base64_encode($email)) ?>&font_size=4&R=FF&G=FF&B=00">

Its just an easy function to write an string in the middle of a picture.



<?php



function imageCenterString(&$img, $font, $text, $color)

{

    if($font < 0 || $font > 5){ $font = 0; }

    $num = array(array(4.6, 6),

I like this better than "tjpoe at cableaz dot com"'s function for wrapping text to fit width (auto-adjusts height as needed) since it doesn't only do 1 word per line.



function make_wrapped_txt($txt, $color=000000, $space=4, $font=4, $w=300) {

  if (strlen($color) != 6) $color = 000000;

  $int = hexdec($color);

  $h = imagefontheight($font);

  $fw = imagefontwidth($font);

  $txt = explode("\n", wordwrap($txt, ($w / $fw), "\n"));

  $lines = count($txt);

  $im = imagecreate($w, (($h * $lines) + ($lines * $space)));

  $bg = imagecolorallocate($im, 255, 255, 255);

  $color = imagecolorallocate($im, 0xFF & ($int >> 0x10), 0xFF & ($int >> 0x8), 0xFF & $int);

  $y = 0;

  foreach ($txt as $text) {

    $x = (($w - ($fw * strlen($text))) / 2);

    imagestring($im, $font, $x, $y, $text, $color);

    $y += ($h + $space);

  }

  header('Content-type: image/jpeg');

  die(imagejpeg($im));

I've made a little modification of the (quite usefull) imagestringcutted function (when align=center, it doesn't work well for me if x1!=0) so juste replace the last line with :



<?php

   [...]

   else imagestring($img,$font,$x1+($x2-$x1)/ 2 - strlen($text) * $fontwidth / 2,$y,$text,$color);

}

?>

The built-in fonts used to be in latin-2 (iso8859-2) encoding. For some time, they are in latin-1 (iso8859-1) encoding. There is no way to change the encoding at all. If you need to use any other encoding, you have to use TrueType fonts.

Here's a simple function for creating an aligned string which is cutted to match the space between $x1 and $x2

<?php

function imagestringcutted($img,$font,$y,$x1,$x2,$text,$color,$align="center") {

    $fontwidth = imagefontwidth($font);

    $fullwidth = strlen($text) * $fontwidth;

    $maxwidth = $x2-$x1;

    $targetwidth = $fullwidth-(4*$fontwidth);

    if($fullwidth > $maxwidth) {

        for($i = 0; $i < strlen($text) AND ((strlen($text)-($i-4))*$fontwidth) > $targetwidth ;$i++) { }

        $text = substr($text,0,(strlen($text)-$i)-4)."...";

    }

    if($align == "left") imagestring($img,$font,$x1,$y,$text,$color);

    elseif($align == "right") imagestring($img,$font,$x2 - ((strlen($text) * $fontwidth)),$y,$text,$color);

    else imagestring($img,$font,($x2-$x1)/ 2 - strlen($text) * $fontwidth / 2,$y,$text,$color);

}

?>

Usage:

<?php

imagestringcutted($img,$font,$y,$x1,$x2,$text,$color,$align);

?>

Will create a string $text, which is cutted if it's too long to match between  $x1 and $2, on $img with font $font and color $color at height $y and with align to $align.

Hope it will help some people.

Sorry for my bad English.

hello, I noticed that if you put a rand(3,5) it will put random sizes of font to each character put on the image. this is very useful when programming captchas for anti-spam form verification.

If you are looking for a way to generate a "CAPTCHA" image for a form verification (to verify it is not a robot), have a look at this : http://blog.theoconcept.com/static/distortion/



It gives an animated image with the parameter string, with distortion, here is an example :

There is a small error in the function for horizontal and vertical centering by "jurgen dot vanoosterwijck at pandora dot be"



the line 



 $cy = (imagesy($img)/2) - (imagefontwidth($font)/2);



should be



 $cy = (imagesy($img)/2) - (imagefontheight($font)/2);

There is an error in "tjpoe at cableaz dot com" 's function ImageStringWrap. Instead of 



    else

           $string = $text;



there should be



     else

           $string = array($text);



for function to work for strings with only one word. Otherwise it works like a charm, thanks.

i modified the centering functions and created this which centers each word on it's own line. You can adjust the spacing with the $valign var. currently no implimentation if text is too large for image. strings are tokenized by space, but can obviously be changed. 



function ImageStringWrap($image, $font, $text, $color)

{

  $fontwidth = ImageFontWidth($font);

  $fontheight = ImageFontHeight($font);

  $words= str_word_count($text);

  if ($words > 1){

    $string=array(strtok($text,' '));

    for ($i = 1 ; $i <= $words ; $i++){

      $string=array_merge($string,array($i=>strtok(' ')));

    }

  }

  else

    $string=$text;

  $vspace=4;

  $y=((imagesy($image)-($fontheight*$words)-($words*$vspace))/2);

  foreach($string as $st){

    $x=((imagesx($image)-($fontwidth * strlen($st)))/2);

    ImageString($image,$font,$x,$y,$st,$color);

    $y+=($fontheight+$vspace);

  }

}

hope this is helpful

This code produces a png image of the text within the query. It autofits to the length of the string. 

Usage: http://yoursite.com/text.php?abcdefg+hijk



Use + to produce a space in the image. The + can be excaped with a carat (^). Most other symbols work fine in the query string, like the ?.



<?php

header ("Content-type: image/png");

$string = $_ENV["QUERY_STRING"];

$md5 = md5($string); //just so we don't convert valid text into a +

$string = str_replace("^+", $md5, $string); //replaces ^+ with long, unnatural string

$string = str_replace("+", " ", $string); //replaces + with space

$string = str_replace($md5, "+", $string); //replaces the long, unnatural string with +

$width  = imagefontwidth($font) * strlen($string);

$height = imagefontheight($font);

$image = @imagecreate($width+2, $height+2);

$black = imagecolorallocate($image, 0, 0, 0); //background

$white = imagecolorallocate($image, 255, 255, 255);

imagestring($image, 2, 1, 1,  $string, $white);

imagepng($image);

imagedestroy($image);

Based on the previous example, here's how to center a string both horizontally and vertically...



<?php

function imagestringcentered ($img,$font,$text,$color) {

 while (strlen($text) * imagefontwidth($font) > imagesx($img)) {

  if ($font > 1) { $font--; }

  else { break; }

 } 

 $cy = (imagesy($img)/2) - (imagefontwidth($font)/2);

 imagestring($img,$font,imagesx($img) / 2 - strlen($text) * imagefontwidth($font) / 2,$cy,$text,$color);

}

My version of the centered string, it decreases the font number (since I've noticed smaller numbers are smaller fonts) until 1 if the string won't fit. Then it will give up.

If you are looking to center the text, use the following function; I'm not promising perfection...



function imagecenteredstring ( &$img, $font, $xMin, $xMax, $y, $str, $col ) {

    $textWidth = imagefontwidth( $font ) * strlen( $str );

    $xLoc = ( $xMax - $xMin - $textWidth ) / 2 + $xMin + $font;

    imagestring( $img, $font, $xLoc, $y, $str, $col );

}

Drawing a string as an image is a handy way to disguise an eMail address so spam sniffers can't get it as easily. The only catch to creating a dynamic image with your eMail in it is the eMail to be displayed must be passed via the query string to enable static HTML to use it. So, the eMail must be encrypted slightly in order to not defeat the purpose of not typing your eMail address outright. I wrote the following script to do so:



Save the following as email.php

<?php

    if ($_GET['addr'] != "") {

        $msg = $_GET['addr'];

        $msg = preg_replace("/\[dot]/",".",$msg);

        $msg = preg_replace("/\[at]/","@",$msg);

        $final = "";

        for ($i=0; $i<=strlen($msg); $i++) {

            $final .= substr($msg, strlen($msg)-$i, 1);

        }

        $msg = $final;



        $char_width = 8;

        $char_height = 17;

        $padding = 3;

        $width = $padding*2+strlen($msg)*$char_width;

        $height = +$padding*2+$char_height;

        $im = imagecreatetruecolor($width,$height);

        imagealphablending($im, FALSE);

        imagesavealpha($im, TRUE);

        $bg = imagecolorallocatealpha($im, 255, 255, 0, 100);

        $text = imagecolorallocatealpha($im, 0, 0, 0, 0);

        imagefilledrectangle ($im, 0, 0, $width, $height, $bg); # Make transparent

        imagestring($im, 4, $padding, $padding, $msg, $text);

    } else {

        $im = imagecreatetruecolor(1,1);

        imagealphablending($im, FALSE);

        imagesavealpha($im, TRUE);

        $bg = imagecolorallocatealpha($im, 255, 0, 0, 125);

        imagefilledrectangle ($im, 0, 0, 1, 1, $bg); # Make transparent

    }

    header('Content-type: image/jpg');

    imagepng($im);

    imagedestroy($im);



?>



If the script is called without an eMail address, it outputs a 2x2 transparent image.



To call the script to generate the eMail "user@home.com", the HTML tag would be:



<img src="email.php?addr=moc[dot]emoh[at]resu">



To 'encrypt' the eMail address to pass to the script, write the address backwards and replace "." with "[dot]" and "@" with "[at]". It's not the most ironclad protection, but it thwarts most casual eMail sniffers.

A simple example:

To make one line of text fit in the image.



<?php

header ("Content-type: image/png");

$string = "spam@mvoncken.nl";                                              

$font   = 4;

$width  = ImageFontWidth($font) * strlen($string);

$height = ImageFontHeight($font);



$im = @imagecreate ($width,$height);

$background_color = imagecolorallocate ($im, 255, 255, 255); //white background

$text_color = imagecolorallocate ($im, 0, 0,0);//black text

imagestring ($im, $font, 0, 0,  $string, $text_color);

imagepng ($im);

?>



I use something like this for spamprotection of my visitors (pass userid as an url-parameter for this php)

When setting the font, any integer less than 1 defaults to 1, and any integer greater than 5 defaults to 5.

Width ImageString, the strings you draw are not automatically wrapped width the edge of the image. You may use this function to automatically wrap them:



function ImageStringWrap($image, $font, $x, $y, $text, $color, $maxwidth)

{

    $fontwidth = ImageFontWidth($font);

    $fontheight = ImageFontHeight($font);



    if ($maxwidth != NULL) {

        $maxcharsperline = floor($maxwidth / $fontwidth);

        $text = wordwrap($text, $maxcharsperline, "\n", 1);

      }



    $lines = explode("\n", $text);

    while (list($numl, $line) = each($lines)) {

        ImageString($image, $font, $x, $y, $line, $color);

        $y += $fontheight;

      }

}



So, in particular, if you want to wrap a text with the edge of the Image, you may do:

ImageStringWrap($img, $font, 0, $y, $text, $color, ImageSX($img) );

If you find that you are getting two characters on the end of your imageString that look like a Y and an upside down L then they're probably representations of CR/LF.  Try trim()ing the string before outputting it.  (I was sooo sure this was a bug <g>)
