GD colour problem.

Hey folks, again.

 

if ($back == "m") //$back is a value pulled from a db; that works perfectly.
    {
        $wid = $rowing['width'];
        $hei = $rowing['height'];
        createthumb("660x240background2.gif", "./user/" . $user . "_back.gif", $wid, $hei);

        $image = imagecreatefromgif("./user/" . $user . "_back.gif");
        $blue = ImageColorAllocate($image, 200, 200, 255); // prepare some blueness
        $black = ImageColorAllocate($image, 0, 0, 0); // ... and whiteness
        $im = ImageCreate(300, 35);
        $black_a = imagecolorallocate($im, 0, 0, 0);
        $white_a = imagecolortransparent($im, $black_a);
        $white = ImageColorAllocate($im, 255, 255, 255);
        ImageFill($im, 0, 0, $white_a);
        Imagettftext($im, 15, 0, 10, 30, $white, $font, $user . "'s Shoutbox");

        $cur_line_y = 65; // This stores how far down the image the current line will print

        $postperpage = 11;
       }
elseif ($back == "u")
    {
        $wid = $rowing['width'];
        $hei = $rowing['height'];



        //        createthumb("./user/".$user."_img.gif", "./user/" . $user . "_backim.gif", $wid, $hei);

        $postperpage = 10;
    }

$sql = ""; // no need for actuall SQL statement - it works.

$result = mysql_query($sql) or die("error in  sqllls: " . mysql_error());


$cur_line_x = 24; // This stores how far across the image the current line will print
$pagecharwidth = 75; // this is the maximum length of the line before it wraps;
$lineheight = 18; // This is how much to move down to print the next line
$pagelinelimit = 1; // How many of each comment appears per page.


//ImageString($image, 3, 15, $cur_line_y, trim(stripslashes($wordwrapped[0])), $black);

$numberOfLines = $pagelinelimit;

{

if ($name == "[] ")
        {
            $name = "";

            $line = $name . $line;
        }
        else
        {
            $line = $name . $line;

        }

//code for emoticons.

//add shouts to image!
        if ($back == "m" )
        {
            if ($color == "white" || $color == "yellow" || $color == "green" || $color ==
                "orange" || $color == "aqua")
            {
                Imagettftext($image, 10, 0, $cur_line_x, $cur_line_y, getColor($color), getfont
                    ($font), trim($line));


            }
            elseif ($color != "white" || $color != "yellow" || $color != "green" || $color !=

            }
            else
            {

                    ($line));


            }

        }
        elseif ($back == "w" )
        {

            $blac = imagecolorallocate($image, 0, 0, 0);

            if ($color == "black" || $color == "purple" || $color == "blue" || $color ==
                "emerald" || $color == "red")
            {
                Imagettftext($image, 10, 0, $cur_line_x, $cur_line_y, getColor($color), getfont
                    ($font), trim($line));


            }
            elseif ($color != "black" || $color != "purple" || $color != "blue" || $color !=
                "emerald" || $color != "red")
            {
                Imagettftext($image, 10, 0, $cur_line_x, $cur_line_y, $blac, getfont($font),
                    trim($line));


            }
            elseif ($font == "fixedsys" || $font == "Courbd" || $font == "arial" || $font ==
                "timesnr" || $font == "calibri" || $font == "comicsans" || $font == "palab")
            {
                Imagettftext($image, 10, 0, $cur_line_x, $cur_line_y, getColor($color), getfont
                    ($font), trim($line));


            }
            else
            {
                Imagettftext($image, 10, 0, $cur_line_x, $cur_line_y, $white, "courbd.ttf", trim
                    ($line));


            }

           }

 

Depending on the values of $back, the background of the image changes and the font colours also change. This code works so far.

 

Problem code

 

elseif($back == "u")
           {
		   if ($color == "white" || $color == "yellow" || $color == "green" || $color ==
                "orange" || $color == "aqua")
            {
                Imagettftext($image, 10, 0, $cur_line_x, $cur_line_y, getColor($color), getfont
                    ($font), trim($line));


            }elseif ($color != "black" || $color != "purple" || $color != "blue" || $color !=
                "emerald" || $color != "red")
            {
                Imagettftext($image, 10, 0, $cur_line_x, $cur_line_y, $white, getfont($font),
                    trim($line));


            }
            elseif ($font == "fixedsys" || $font == "Courbd" || $font == "arial" || $font ==
                "timesnr" || $font == "calibri" || $font == "comicsans" || $font == "palab")
            {
                Imagettftext($image, 10, 0, $cur_line_x, $cur_line_y, getColor($color), getfont
                    ($font), trim($line));


            }
           else
           {
               Imagettftext($image, 10, 0, $cur_line_x, $cur_line_y, $white, "courbd.ttf", trim
                 ($line) . "    ");


           }
	}
    
        $cur_line_y += $lineheight;


    }
}

 

The problem is that when $back == "u", for the first two comments the colours are normal then after that the older comments turn black; the newest comment is in colour but it also changes the colour of the $im that says "User's Shoutbox", which is created as a seperate image.

 

I can't, for the life of me, see the problem.. can you?

 

An example: The oldest comment was white, then I added the Yellow comment, the white one turned black.

 

 

Hope that makes sense,

*shameless bump*

 

Anyone got any ideas?

W00t, triple post.

 

Anyways. I've fixed it now!

 

It's always the simple things.. I used imagecreatetruecolor($wid, $hei); instead of imagecreate(); and it works perfectly now. Before, because of the photo background, I was running out of colours (so to speak). It works poifectly now.

quadruple post. xD

 

The imagecreatetruecolour only solved it for a little while, allowing one more comment of colour than before, now the comments do the same thing.

 

Any ideas why when a new comment is posted, the imagecolorallocate fails and the comments turn black?

 

supposed to be like:

 

- plain background, colours work!

 

but ends up like:

 

- detailed background, colours only work part of the time.

 

Please reply if you have any theories.
