Transparent Background


i'll try to explain myself the best i can, here is the problem:

i have a html page and inside this i want to put an iframe that contains a php page. That's ok, i can do it and it works, but the problem is that i can't make that php document to have transparent background.

it turns white. Is it because of the iframe? the php document has transparent background, but when i see it inside the iframe it doesn't work.

PHP (GD) Created Transparent PNG: AlphaImageLoader Makes Black Parts Transparent Instead Of Transparent Color Set With PHP
I have a problem with PHP (GD) created transparent PNG and Microsofts
AlphaImageLoader.

You will immediately see what the problem is if you view
http://www.useful-scripts.biz/test/.../transpng_2.php with IE 7
or Firefox and then with IE 6. It seems that the AlphaImageLoader
works correctly on a PNG image that has been created with an image
processor and then uploaded, but not with a PNG image created with
PHP. It seems to ignore the transparent color set with PHP and instead
to render the black color transparent.

The image in question was created using this code:

<?php
$source = imagecreatefrompng("parrot_orig.png");
$transp = imagecolorallocate($source,255,0,0);
imagecolortransparent($source,$transp);
imagefilledrectangle($source,15,15,70,70,$transp);
imagepng($source,"parrot_php.png");
?>

The HTML used on the page is this:

Transparent GIF
I am trying to resize transparent GIF images, so I was reading, and they say to use fopen, fread, and read the first 13 bytes... OK, so I read in a transparent gif, and the first 13 bytes... and echo it out to the screen, and I get this: GIF89a›&#65533;s&#65533;÷&#65533;&#65533;What am I supposed to do with that? they then say "allocate that color as transparent, and use imagecopy(); to set the transparency back."

Transparent Image
Hi!

Here's a piece of code:

[begin]

<?php

Header('Content-type: image/png');

$sz = "";

$FileValue = 1000;

$i = strlen($FileValue);

for ( $j = 0; $j < 7-$i; $j++ )
{
$sz = $sz . "0";
}

$Img = imagecreate(56,13);

$Gold = imagecolorallocate($Img,148,128,100);

$Gray = imagecolorallocate($Img,32,32,32);

ImageFilledRectangle($Img,0,0,55,12,$Gray);

imagestring($Img,4,0,0,$sz.$FileValue,$Gold);

imagepng($Img);

ImageDestroy($Img);
?>

[end]

OK. Calling this script I have a png picture back.

Now I add imagecolortransparent($Img,$Gray); just before imagepng() and OK
again, I have a transparent picture back. But now, if I add:

$r = imagerotate($Img,90,0);

imagepng($r);

just after the imagecolortransparent() instruction seen above, I get a
rotated picture, but not transparent. How to solve that? I've used a plenty
of tricks, no one works.

Transparent Overlay Watermark - On The Fly?
Is it possible to overlay a transparent watermark on an image -
dynamically?

I'd like the result to look like this example:
<http://www.cycletourist.com/temp/photo.php>

That is a bit of overkill, but you can see what I mean. The watermark
image (a png image) is included separately below the photo.

I tried using a class from phpclasses.org
<http://www.phpclasses.org/browse/package/1580.html...
but the result looks horrible. The transparency does not work.

I found one other method through Google,
<http://www.sitepoint.com/article/watermark-images-php>
but it did not work, either.

Can this kind of transparent overlay be done on the fly with GD lib?

Define The Transparent Color
I've made a script that takes images (in gif,jpg & png) and makes their thumbs in jpg format. Now, the problem is if I have a transparent gif when saved to jpg the part of the original picture that is transparent turns black in the new thumb. My question is: how can I define that the transparent part gets the color i want it to get (white is what i need) ?

Actually, I now what in theory should be done. I should change the r,g,b values of the color that has aplha=127 (and that's not a problem with imagecolorset()), but also I should change the alpha of that color to 0. how can that be done ? My quess is that that is the right way to do it.

Create Or Resize Transparent .png - Drop Shadow - GD IM
I've searched and d/l'd but cant seem to find a way of creating
a semi-transparent drop shadow for an image.

Let me say, be fore I go on, I *do not* want one of those scripts that
resizes your image a bit to the left and bottom, and then grafts a
shadow onto it. I want to use a full shadow (it would be about as big
as the image) and shift it a bit with CSS. So, I will have the image
sitting in a DIV which will have the shadow as a bg. This works fine
doing it manually.

So, I would like to find one of two alternatives:

1. (best) Create the shadow from given parameters(size, darkness,
spread, etc.) I will write the .png to a folder, I dont really need to
create it dynamically each time, but want the ability for the future
(galleries) and for when I'm in development and images are changing,
moving around, etc.

2. (will work) Take a pre-existing shadow and resize it as needed, but
has to keep the transparency.

In Background
Here's my situation. I'm creating a website (basically a store) and in the admin section users will want to download zip files of images or products added in the last 7 days, last 2 weeks and the last month.

I have scripted a cron to run every 24 hours to zip all the images and this process takes over 1 minute (there's over 6,000 images!!) and the size of this is 250MB. This has now taken me to my quota on my webspace of 500MB (including all the individual images)

I have decided the only way to do this is dynamically create the zip when the user requests it. As PHP times out after 30 seconds it needs to do it's stuff in the background and display a message saying something like' We'll email you with the zip file in 5 minutes or so'.

Run A Php In The Background Using Http
i have a script (script1) which needs to call another script (script2).
It should not wait for the answer, so script2 should run in the background.

I really need to call the php script using:
http://urlof myscript/script2.php

I don't want to use it as a cgi and use CLI.

I did a test with fsockopen and curl and a timeout of 10 seconds and call
http://urlof myscript/script1.php from my browser:
Script1 stops after 10 seconds => OK
Script2 has been called by script1 and continue to run in the background
=>OK
After 60 seconds Script2 is killed by php!! => KO :(

The script is working fine if i call http://urlof myscript/script2.php from
my browser. It needs around 120 seconds to finish.

Why is it stopping after 60 seconds when I use fsockopen and call it from
script1?

Here is the script in SCRIPT1:
$fp = fsockopen("$host", 80, $errno, $errstr, 30);
stream_set_timeout($fp,10);
if (!$fp) {
echo "$errstr ($errno)<br />
";
} else {
$out = "GET $path HTTP/1.1
";
$out .= "Host: $host
";
$out .= "Connection: Close

";

fwrite($fp, $out);
$status = socket_get_status($fp);

while (!feof($fp) && !$status['timed_out']) {
echo fgets($fp, 128);
$status = socket_get_status($fp);
}
fclose($fp);
}

I have added this in SCRIPT2:
ignore_user_abort(FALSE); // becareful, FALSE really means it should ignore
user abort !!!
set_time_limit (120);
ini_set("max_input_time",120);
ini_set("max_execution_time",120);

Do you have any idea?

A Way To Get Current Background?
I have several websites running on a global script. Some pages, the backgrounds black, other, white. Sometimes people have the taste of posting black font on a black background, or white font on a white background.

What I wanted is to know if theres a way to 'check' the current background color? Because I can then add in the script to 'change' any incorrect colors before posting. I'm not sure if theres a way for PHP to tap into CSS and check, but it would be alot easier to change the global script since its *Checking* for the background color rather then me do it per site and change it manually.
