Hello all. I found this code on the net regarding how to make a random quote generator. Anyway, this code creates an image that pulls its text from a quotes.txt file.
Anyway, it pulls the information just fine. However, I want to be able to INCLUDE this file into another php file. I don't know exactly how, since this file sends HEADER code to the browser, which will probably make things a bit sticky...
More importantly, I am interested to hear how I can generate this image and force it to have a transparent background. Now, due to the version of my GD, I cannot create a GIF. I can however create a PNG file. Does anyone know a way to force the PNG to have a transparent background? That way I can include it in my other PHP file without problem. If not, I can probably make do.
Thanks for your time!!!
Here is the code:
<?php
/*
Quote generator 0.01
This scripts generates a gif image produced on the fly with the gd-library.
I used it to get quotes from a file and display them in an image. This was made to
make it possible for "out-site-users" to show the quotes i have collected.
It expects to get the following variables sent to it:
$filename : the name of the file containing quotes or other things separated with #.
$path_to_font_file : the path to the true type font file
$steal : (optional) This makes it possible to output a specific line in the file. Good for debugging.
The script is limited to output 3 lines(and 1 static line) in the image. It can easily be changed by doing it
bigger and add more lines at appropriate places.
The script could be included on a page by calling it with a regular <img src="/path to script">.
