I made a small code to make a random text-sig some while ago, and today I added Sign the Petition to it, but I realised it was too small to fit the text, so I made it double the size, but not it doesn't look nice with smaller texts anymore...


Anywaaaay, what im trying to ask is , can someone help me to make it auto-adjust the size to the text.

I already tried it with imagettfbox but couldn't get it to work. Because I don't think my server can use ttf font's, and I can't change any settings cause it's my hosting company's server.

TIA

And below my code

code:

---

<?php


//randomizer
srand((float) microtime() * 10000000);
$input = array("Ezra", "TSDME", "MsgPlus!", "Nintendo", "SPAM", "Web2Messenger", "Sign the Petition");
$rand_keys = array_rand($input, 2);
$string =  $input[$rand_keys[0]];

//Header info
header("Content-type: image/gif");

//
$im = @imagecreate(160, 20);
$background_color = imagecolorallocate($im, 100, 100, 100);
$text_color = imagecolorallocate($im, 000, 000, 200);

//
imagecolortransparent($im, $background_color);
imagestring($im, 5, 7, 3, $string, $text_color);
imagegif($im);
imagedestroy($im);

//statistics
include_once('connection.inc.php');
opendb();

$query = "SELECT * FROM stats";
$result = mysql_query($query);

while($row = mysql_fetch_array($result)){
$sts = ($row[stats]) + 1;
}

$sql = "UPDATE stats
           SET stats = '$sts'";
             
mysql_query($sql);
?>

imagettfbox is very picky with the font path. Firstly you should check your PHPinfo to see if freetext (2 if possible) is installed.

Freetext is not installed, Gettext is installed not sure if that's any use to it, but it's called text so I thougt it might be worth telling

And I have PHP4 and 5 btw, so I can also use PHP5only functions if needed.

Well... check if the GD section of any of both versions says something about fonts or ttf?

Do you get an error when you use that function and not change the headers to image?

Stupid Windows FTP, I needed to upload the .ttf file in binary mode, but somehow Windows transferred in ASCII mode or something, because when I forced Binary mode with FireFTP It worked

Anywaay, still working on it, the text looks a bit strange, I'll see if I can make it better and to get the resizing to work

progress: http://scripts.tsdme.nl/randomgif.php

I don't like the font? Or is it my explorer?

I don't like it either it's supposed to be arial, but it's buttugly right now

Anywaay, the resizing works

Now, I just need to make the font look nice

UH.... It's not showing on IE , it's just a GIF with transparancy...

Hmm, nvm, working now on IE , crazy IE...


So does anyone know how to make it look nicer?

BTW: I still want a transparent background.

Gif will always do hard backgrounds.

Youy may use PNG.

code:

---

$img = imagecreatetruecolor($width, $height)
imageAlphaBlending($img, true);
imageSaveAlpha($img, true);
imagecolorallocate($img,0,0,0,127);
[/color]

This will make a transparent backgrounded PNG

You must note that MSIE 6 is the only browser that does not support them. 7 is said to do.

---

On the php.net pages it says I can't use imagesavealpha when imagealphablending is enabled

And I keep having a black background for some reason

hmm i always found that using the code below worked alot better for transparent backgrounds than the whole alpha blending thing. (use the below code after you create your image)

code:

---

$tran = imagecolorallocate($image, 233,231,222);
$tran = imagecolortransparent($image,$tran);
imagefill($image,0,0,$tran);

---

That will still cause the same hard-edges effect to any ttftext he adds...

Hmm, but I keep having a black background if I use a TrueColor image...

Oh, sorry
it's colorallocatealpha($img,$r,$g,$b,$alpha)

Still the black background

This is what I have now: (Not all of it, just the image part )

code:

---

$im = imagecreatetruecolor($width, $height);
imagealphablending($im, true);
imagesavealpha($im, true);
imagecolorallocatealpha($im, 0, 0, 0, 127);
$font['color'] = imagecolorallocatealpha($im, 0, 0, 255, 25);
imagettftext($im, $font['size'], 0, 0, 15, $font['color'], $font['path'], $string); //TTF text
imagepng($im);
imagedestroy($im);

---

code:

---

$im = imagecreatetruecolor(50, 50);
imagesavealpha($im,true);
imagealphablending($im, false);
$bg = imagecolorallocatealpha($im, 0, 0, 0, 127);
imagefill($im,0,0,$bg);

$font['color'] = imagecolorallocatealpha($im, 0, 0, 255, 25);
imagettftext($im, 10, 0, 0, 15, $font['color'], $font['path'], 'test'); //TTF text
header("Content-type: image/png");
imagepng($im);

imagedestroy($im);

---

Excellent

I read about that imagefill, but it gave me a 500 error when I tried to use it...

Anywaay, thanks a million

I'll use a simple palette with ugly text for IE users
and this one for better browser users

Or just do what I did with my sig: a version for IE and one for standars-complying

(look at it in IE)

I have it like this.
Alpha transparancy for good browsers and normal (ugly) transparancy for IE.
