As you haven't stated what error you're getting my guess is that most likely it's because you don't have the font file installed on your "non-windows" machines. Another thing is that imagettftext() seems to be very finicky and needs the full path to the font file. -- Jason Wong -> Gremlins Associates -> www.gremlins.biz Open Source Software Systems Integrators * Web Design & Hosting * Internet & Intranet Applications Development * -- Search the list archives before you post http://marc.theaimsgroup.com/?l=php-general -- /* One enemy soldier is never enough, but two is entirely too many -- Murphy's Military Laws n68 */ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] imagettftext() question
I've written a script that displays a graph of some data from a text file. Beneath each bar in the graph is a text label. I read the php.net documentation and it seemed that imagettftext() was the easiest function to get text in an image with, so I used that. Here is the text-display code (syntax is all correct): imagettftext($im, 10, 0, $i * 100 + 10, 190, $black, "arial", str_pad($candidates[$i][0], 12, " ", STR_PAD_BOTH)); This code works perfectly well on both windows machines I've tried it on, but causes an error in the image on both non-windows (Unix variants) machines I've tried it on. Does anyone have -any idea why its breaking? -a solution to get it to work on *nix machines? -a different way to display text in an image? Thanks a lot. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] imagettftext question
To change your Image color use ImageFill: ImageFill($im,$gifwidth,$gifheight,ImageColorAllocate($im,235,235,235)); Then, in your ImageTTFText, you can set the font: ImageTTFText($im, 11, 0, 20, (540-20),-$black,"../fonts/arial.ttf", "Source: SEER 12 Program"); I recommend using -$fontcolor for almost everything. Sometimes it's not as good for the larger fonts (they look a little stairsteppy) but it's almost always better for the smaller fonts.
