Dynamic text gd image loadfont90 ???? help

[Paulinit]

Hi all,

I am having a problem with this and I just can’t get my head round it.
Any way I was given some php to display text in an image "good stuff"

But and the but is!!!, for some rezone It does not work when I load it.... I have a version of this that does not load a font and works well, but the wife (the protect is for her) wants the text I a certain type of font on her image.

I have read that I could use loadfont, or something like that but being new to this I am nut sure how to implement it into the code.

would one of you be as so kind as to help me out one this one e.g amend my code for me please and a pointer as to what is goning wrong.

Many thanks
Paul

Is the font file 'ITCKRIST.TTF' inside the same directory as the PHP file?

If not, try defining the GDFONTPATH environment variable:

putenv('GDFONTPATH='.realpath('../fonts'));

If it is in the same dir, use this:

putenv('GDFONTPATH='.realpath('.'));
$font = 'ITCKRIST'; // Note: no extension

// .... //
imagettftext($image, 20, -2, $x, $y, $color, $font, $text);
// .... //

Sorry no show :queasy:

The url for the font is

http://www.sticky-toffee.com/sign/ITCKRIST.TTF

and i have amended the code to: but still no show :o

<?
function ImageStringWrap($image, $font, $x, $y, $text, $color, $maxwidth)
{
//  $font = ImageLoadFont("ITCKRIST.TTF");  // has no effect
putenv('GDFONTPATH='.realpath('http://www.sticky-toffee.com/sign/ITCKRIST.TTF')); 
$font = 'ITCKRIST'; // Note: no extension 


   $fontwidth = ImageFontWidth($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)) {
    imagettftext($image, 20, -2, $x, $y, $color, $font, $text);  //  imagettftext($image, 20, -2, $x, $y, $color, 'ITCKRIST.TTF', $text);
	// ImageString($image, 20, $x, $y, $line, $color);    //imagestring will work but not load the font.!!! 
      # $y += $fontheight;

 }
}
header("Content-type: image/jpeg");
$string = $_GET['text'];

$im = imagecreatefromjpeg("einsteinshow.jpg");

$alpha = 95;
if (strlen($string) < 23) $alpha = 60;
if (strlen($string) > 90) $alpha = 105;

$color = imagecolorallocatealpha($im, 255, 255, 255, $alpha);
ImageStringWrap($im, 5, 140, 150, $string, $color, ImageSX($im)-300);
imagejpeg($im);
imagedestroy($im);
?>

no no no no no....

The path you need to put is the relative path to the font file on your system....

/
|
+ fonts/
| |
| -- ITCKRIST.TTF
|
+ folder/
| |
| -- somepage.php

Given that setup, the path would be: ../fonts

So, do you have the TTF file uploaded to your webserver? You should. Now, once it's uploaded, is it in the same folder/directory as the PHP file that is looking for it? Best bet should be yes.

Then, change realpath('http://......') to realpath('.') once the font is in the same directory as the PHP file that's using it.

Then try again.

Sorry the direct url was me tring to be smart, but the font is sitting next to the php page on the sever

i amended the code but still

<?
function ImageStringWrap($image, $font, $x, $y, $text, $color, $maxwidth)
{
//  $font = ImageLoadFont("ITCKRIST.TTF");  // has no effect
putenv('GDFONTPATH='.realpath('.')); 
$font = 'ITCKRIST'; // Note: no extension 



   $fontwidth = ImageFontWidth($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)) {
    imagettftext($image, 20, -2, $x, $y, $color, $font, $text);  //  imagettftext($image, 20, -2, $x, $y, $color, 'ITCKRIST.TTF', $text);
	// ImageString($image, 20, $x, $y, $line, $color);    //imagestring will work but not load the font.!!! 
      # $y += $fontheight;

 }
}
header("Content-type: image/jpeg");
$string = $_GET['text'];

$im = imagecreatefromjpeg("einsteinshow.jpg");

$alpha = 95;
if (strlen($string) < 23) $alpha = 60;
if (strlen($string) > 90) $alpha = 105;

$color = imagecolorallocatealpha($im, 255, 255, 255, $alpha);
ImageStringWrap($im, 5, 140, 150, $string, $color, ImageSX($im)-300);
imagejpeg($im);
imagedestroy($im);
?>

Do you get an image with no text, or do you get no image at all?

[Paulinit]

It returned an image with on text

Forgive the image it's is on temp loan

[bpat1434]

Don't know what to tell you... it should work....

[Paulinit]

I think it’s my GD library and version of PHP perhaps :rolleyes: …I am currently on php 4.4.2 and GD 2.0.
I will have a moan :glare: at my host provider to get them to upgrade this.
Well let’s hope that this is the problem and that they will upgrade the server.

Many thanks for your help with this it was very much appreciated
And in the mean time, if you have a drain wave, please do tell.

Paul
