I wanted to put my last tweet in this signature... but since my twitter account is protected it's a little bit harder

Now you're just showing off y0r l33t 5k1lls

[dazbobaby]

seeing as you're better at this than me Sparky, any idea how to input and output PNG transparency?

[dazbobaby]

for anyone interested, here is my signature.php customised for 600x150px random images:

$server = "localhost:8080"; //Your subsonic server
$xml = @simplexml_load_file("http://".$server."/rest/getNowPlaying.view?u=".$admin."&p=".$adminpass."&v=1.5.0&c=signature");
if($xml==false) {
goto offline;
}

//Timestamp
//Different Timezones supported: http://phptutorial.info/?timezones
date_default_timezone_set('Europe/London');
$time = "My local time: ".date("l: D: M: d: H:i");

//If the server is online, check what the monitored user is listening or watching, and jump to the right code...
foreach($xml->children()->children() as $second_gen) {
$math = floor($second_gen['duration']/60);

[SparkyRih]

seeing as you're better at this than me Sparky, any idea how to input and output PNG transparency?

I guess you're looking for this function?
http://www.php.net/manual/en/function.i ... parent.php

Example:
http://develop.schattorie.nl/signatures ... c/test.php

[dazbobaby]

I don't think so, isn't that taking one colour and making it transparent?

What I was thinking is keeping transparency from an original:

music6.png

And making the sig code keep it after it's added artwork and text.

[SparkyRih]

I see, it doesn't work... let me have a look...

Edit: This is what you wanted

Quick questions on this forum signature....

Can it be used on ANY forum, or only on this one?
If I post something in a forum, and the .jpg file is linked to in the image, will that image actually "change" if I am listening to another song, or to no song at all? (ie. if I am listening to "Metallica - One" when I post a message, then the following day, I go back to the thread I posted in, but am not currently listening to anything, will it still show I am listening to Metallica, or would it now say I am not listening to anything?

Thanks!

If you're allowed to link to a "remote image", than the answer is simply yes...

The image you see below doesn't really exist, it's generated at the moment you load or refresh this page...
The background is a real image, but the text (and coverart image if I'm actually listening to something) on it is printed on it by my script...

1. The browser asks my server for signature.png.
2. I told the server that signature.png is actually signature.php (using a little script), so my server runs the script
3. the script asks subsonic for the data and gives real image data back to the browser

[gurutech]

ok, I have the signature files copied to a ./signatures folder, and I modified the script, and if I browse to the URL I can see the correct image, however I do not see any text on the image at all.

I tried all three of the standard images (that came with your script), and can view each of them, but no text on any of them.

I tried going through the signature.php file and it looks like there are some x and y parameters to specify the starting point for the text, which I have left at the default (160, 65).

I did resize the actual back2.png file so it would fit within the specs on the forum I wanted to use it on (510x100 max, ended up as 434x100)

My latest release has image tranparency by default now

I'm working on a multiuser plugin for my subsonic registration engine now...
This plugin will make it possible for every registered user to create their own image via a webpage...

[dazbobaby]

Nice going Sparky, I'm currently working on drop shadow, something impossible in GD2 (or so I've heard).
I tried imageconvolution with Gaussian blur but failed, so instead I'm trying to replicate the text, darken it, and move it slightly to create the effect of a drop shadow.

Throw me a rope I'm going in
