[PHP] text to image
Hello, I am thinking to create php script to dynamically convert a text string to image. My questions are: 1. with a given text string, say hello, world, is it possible to dynamically convert it to an image? and what php built-in functions can be utilized? 2. if I want to use true-type verdana font, can I just upload the windows font file to the web server (linux) and use php to load the font? Thanks in advance!

Re: [PHP] text to image
Alex, Easy to do what you want. Check out the image functions in the php manual. There are some font limitations, specifically dealing with alternate characters, but you'll find out what works and what doesn't soon enough.

Re: [PHP] text to image
Hi, THanks for your reply.
I search the manual and created following script.
?
header (Content-type: image/gif);
$im = imagecreate (400, 16);
$black = imagecolorallocate ($im, 0, 0, 0);
$white = imagecolorallocate ($im, 255, 255, 255);
imagettftext ($im, 10, 0, 10, 20, $black, verdana.ttf, date('| l | F | d
| Y |'));
imagegif ($im);
imagedestroy ($im);
?
I got following error msg when ran it:
br
bWarning/b: ImageTtfText: No TTF support in this PHP build in
b/home/dotkard/www/current_time.php/b on line b6/bbr
br
bWarning/b: ImageGif: No GIF support in this PHP build in
b/home/dotkard/www/current_time.php/b on line b7/bbr
I checked the phpinfo but failed to find which variable I should turn on.

Re: [PHP] text to image
Alex,
You should either use png or jpg rather than gif. The most common builds of
the gd library support those image formats--go to the GD Library site to
find out why. The support of ttf fonts should be taken up with your host.
When testing whether the code in your image creation file works, use
something like
a href=your_image_creation_file_name.phpsay something wonderful here/a
and any error messages will be displayed. Once you've got it down pat, then
you can just swap out the line with an image tag, img
src=your_image_creation_file_name.php
$font=./fonts/verdana.ttf; // the path to the font is needed if it isn't
in the same directory as the script
$im = imagecreate (400, 16);
$black = imagecolorallocate ($im, 0, 0, 0);
$white = imagecolorallocate ($im, 255, 255, 255);
imagettftext ($im, 10, 0, 10, 20, $black, $font, date('| l | F | d | Y |'));
header (Content-type: image/png); //header just before the imagepng call.
imagepng ($im);
imagedestroy ($im);
Hope this helps,
Hugh
