First play with GD image creation... crashes and burns.... HELP (please) !!

[Mouse]

Well I have had a little play with this and I am not clear on a couple of bits…

<?php
   $point = 18;
   $text = "Bekky"; // to be users name here

   $size = imagettfbbox($point, 0, "ARIAL", $text);
   $xsize = abs($size[0]) + abs($size[2]);
   $ysize = abs($size[5]) + abs($size[1]);

   $image = imagecreatefrompng("images/badge/sml_nm_tg.png");
   $imagesize = getimagesize("images/badge/sml_nm_tg.png");
   $textleftpos = round(($imagesize[0] - $xsize) / 2);
   $texttoppos = round(($imagesize[1] + $ysize) / 2) + 10;

   $red = ImageColorAllocate($image, 255, 51, 0);
   $grey = ImageColorAllocate($image, 102, 153, 153);

   imagettftext($image, $point, 0, $textleftpos + 1, $texttoppos + 1, $grey, "ARIAL", $text);
   imagettftext($image, $point, 0, $textleftpos, $texttoppos, $red, "ARIAL", $text);

   header("content-type: image/png");
   imagepng($image);
   imagedestroy($image);
?>

 

as you can see there is meant to be red writing with a grey drop shadow but as you can see from this local test screen print…

<img src="http://mouse.nodstrum.com/images/badge/demo.jpg" />

it just isn’t doing the colours thing… even worse <a href="http://mouse.nodstrum.com/nametag.php">when I try this online I get gibberish</a> any ideas? PLEASE????

Try using the function imagecolorclosest() instead of imagecolorallocat().

 

The reason you're getting "gibberish" online is that you're getting warning messages about not being able to find the font you want. Those warnings put out headers which stop the image from displaying as an image. The "gibberish" is the image as displayed with ASCII characters.

Ken, using the function imagecolorclosest() instead of imagecolorallocat() has done the trick, many thanks.

 

The reason you're getting "gibberish" online is that you're getting warning messages about not being able to find the font you want.

 

how can i rectify this, is there a way to find out which fonts are on the server (i assume) or can i put one in there?

 

Many thanks

try this (change the font file path as required)

 

<?php

   $point = 18;
   $text = "Bekky"; // to be users name here
   define ("ARIAL", "c:/windows/fonts/ARIAL.TTF");   // font in ttf function is the font file
   
   $size = imagettfbbox($point, 0, ARIAL, $text);
   $xsize = $size[2] - $size[0];      // size is the diff between left and right cooords, not the sum
   $ysize = $size[3] - $size[1];

   $image = imagecreatefrompng("images/badge/sml_nm_tg.png");
   $width = imagesx($image);
   $height = imagesy($image);
   $textleftpos = round(($width - $xsize) / 2);
   $texttoppos = round(($height - $ysize) / 2) + 10;

   $red = ImageColorAllocate($image, 255, 51, 0);
   $grey = ImageColorAllocate($image, 102, 153, 153);

   imagettftext($image, $point, 0, $textleftpos + 1, $texttoppos + 1, $grey, ARIAL, $text);
   imagettftext($image, $point, 0, $textleftpos, $texttoppos, $red, ARIAL, $text);

   header("content-type: image/png");
   imagepng($image);
   imagedestroy($image);
?>

Many thanks sir but the Define didn't work it out... also isn't that counterproductive if the site user is a a mac or linux addict?
