Okay, I'll try it out tomorrow when I get home from school.

Looking at the image, you might want to trim($song) before assigning it to $message[].

|SiC| — Mon, 24 Feb 2003 23:26:35 +0000

It is all working.

<?php
if ($pw != '[edited out]') { exit(\"What are you doing?\"); }

$textSize       = 2;

$textGutter     = 0;

$paddingBottom  = 4;
$paddingLeft    = 4;
$paddingRight   = 4;
$paddingTop     = 4;

$marginBottom   = 2;
$marginLeft     = 2;
$marginRight    = 2;
$marginTop      = 2;

$message[] = \"|SiC| is currently listening to:\";
$message[] = $song;

$max_length = 0;
foreach ($message as $line) {
    if (strlen($line) > $max_length) {
        $max_length = strlen($line);
    }
}

$textHeight     = imageFontHeight($textSize);
$textWidth      = imageFontWidth($textSize);

$textboxHeight  = (count($message) * ($textHeight)) + ((count($message)-1) * $textGutter) + ($paddingBottom + $paddingTop);
$textboxWidth   = ($max_length * $textWidth) + ($paddingLeft + $paddingRight);

$imgHeight      = $marginTop + $textboxHeight + $marginBottom + 1;
$imgWidth       = $marginLeft + $textboxWidth + $marginRight + 1;

$image = imageCreate ($imgWidth, $imgHeight);

$colorBG        = imagecolorallocate ($image, 200, 0, 0);
$colorBorder    = imagecolorallocate ($image, 153, 153, 153);
$colorText      = imagecolorallocate ($image, 255, 255, 255);

imageFilledRectangle($image, 0, 0, ($imgWidth - 1), ($imgHeight - 1), $colorBG);

for ($i=0; $i<count($message); $i++) {
    imageString ($image, $textSize, ($marginLeft + $paddingLeft + 1), ($marginTop + $paddingTop - $textHeight + (($i+1) * ($textHeight) + ($i * $textGutter))), $message[$i], $colorText);
}

imageRectangle($image, $marginLeft, $marginTop, ($imgWidth - $marginRight - 1), ($imgHeight - $marginBottom - 1), $colorBorder);

imageInterlace($image, 1);

imagePNG($image, \"song.png\");
?>

And if anyone wants to see what it is doing you can see here:
http://www.drewhopkins.com/song/song.png

This is just displaying what song winamp is currently playing. I have a winamp pluging that submits a URL every time the song changes and this is the script it loads from that URL.

*added*
Just in case anyone wants to know $pw and $song are from the URL.

Oh cool. I didn't know that those functions took an optional filename. Very handy.

|SiC| — Mon, 24 Feb 2003 04:49:26 +0000

I got it to work.

<?php
// now send the picture to the client (this outputs all image data directly)
//imageGIF($image);
imagePNG($image);
?>

changed to

<?php
// now save the picture
//imageGIF($image, $filename);
$filename = \"file.png\";
imagePNG($image, $filename);
?>

|SiC| — Mon, 24 Feb 2003 04:37:44 +0000

I'm not getting it to work. Well I got it to display what I wanted the first time, I just can't get your save routine to work.

Mark Hensler — Mon, 24 Feb 2003 01:09:44 +0000

Welcome to TWF!

You mean saving that into a .png file? The easiest way to do that would probably have one script (script1) run the image script (script2), and save the output to a file.

For example: (untested)

<?php
// script 1

ob_start();
if (read_file(\"script2.php?message[]=\".URLEncode('Line 1').\"&message[]=\".URLEncode('Line 2').\")) {
    $image = ob_get_contents();
    if ($fp = fopen(\"image1.png\", \"r+\")) {
        fwrite($fp, $image);
        fclose($fp);
    }
}
ob_end_clean();
?>

And now how would I go about actually saving that as an image. Not just displaying the image when the script is executed?

|SiC| — Sun, 23 Feb 2003 23:50:24 +0000

Yes it's me from G4B2S. I remember you were on these forums so thats why I came here.
