GD intermittent color problem

[helraizer1]

Hey folks, yet again.

[php]


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);

imagecreatefromgif("./user/" . $user . "_img.gif");



$images = imagecreate($wid, $hei);

$imge = imagecreatefromgif("./user/" . $user . "_backim.gif");

imagecopymerge($images, $imge, 0, 0, 0, 0, $wid, $hei, 20);

imagegif($images, "./user/" . $user . "_back_trans.gif");

$image = imagecreatefromgif("./user/" . $user . "_back_trans.gif");

$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;

for ($i = 0; $i < $numberOfLines; $i++)
{
while ($row = mysql_fetch_array($result))
{

$name = "[" . htmlspecialchars_decode($row['username']) . "] "; //it works - returns username
$font = $row['font']; //it works - renders the colour
$color = $row['color']; //it works - changes the font
$line = htmlspecialchars_decode($row['comment']); //it works, posts the shout

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 ==

{
Imagettftext($image, 10, 0, $cur_line_x, $cur_line_y, getColor($color), getfont
($font), trim($line));


}
elseif ($color != "white" || $color != "yellow" || $color != "green" || $color !=
"orange" || $color != "aqua")
{
Imagettftext($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));


}

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

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

if ($color == "black" || $color == "purple" || $color == "blue" || $color ==

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));


}

}


[/php]

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

[php]
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;


}
}
[/php]

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: $back == "u" because it's an uploaded background. The oldest comment was white, then I added the Yellow comment, the white one turned black.

Hope that makes sense; if you need more code, just ask. =)

*bump*

Any one got any ideas?

The process of the background image is that when they upload it as either jpg, gif or png; it is converted to and saved a gif file.

So I uploaded this image

http://www.helraizer.co.uk/mychatbox...ucifer_img.gif

which then is pulled into the code where $back == "u" the first time. It is the saved to the user's specified dimensions. So creates this (700x290, in this case).

http://www.helraizer.co.uk/mychatbox...fer_backim.gif

It is the merged onto a gd made image at the same dimensions, this time at 20% transparency. Which gives this:

http://www.helraizer.co.uk/mychatbox...back_trans.gif

That final, darkened image is what the shouts are written onto. Is there any way this process could be affecting the colours? I can't imagine it can because this process happens seperately each time, before the shouts are written on.

EDIT: Fixed it!

Used imagecreatetruecolor($wid, $hei); instead of imagecreate(). It works perfectly now.

[helraizer1]

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:

http://www.helraizer.co.uk/mychatbox/user/helraizer.gif - plain background, colours work!

but ends up like:

http://www.helraizer.co.uk/mychatbox/user/lucifer.gif - detailed background, colours only work part of the time.

Please reply if you have any theories.

[helraizer1]

Fixed it again. xD

Used the same technique but this time I've made it as png. That way it doesn't run out of colours on the pallete and gives the same result.
