Transparent Watermarks On Images


I'm using the code below to make a watermark and it's kinda working, but I want it semi-transparent as the PNG file is itself.

Is there an easy way of overlaying transparent images in the GD library, so that the original image is merged in such as way that it can be seen through the watermark? Code:

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 .png

Anyway, when I view the page in Internet Explorer, the transparency within the png is replaced with grey?? But when I view it in Firefox it works fine?

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.

PHP Images And Gd
I currently run a popular website and need to be able to use PHP in order to produce signatures for each user. I have been learning image manipulation and things from the gd library for PHP - and am able to load images from files and add text .etc

However, my problem is that I need to load two files - for example, background.png and icon.png - and then combine them so they become one image. The background.png will obviously be the base of the image, and then I need the icon.png image to be loaded and placed on top of the background - at a certain position (lets say, at 120,100).

This is the only thing I cannot seem to achieve - I've searched google, I've search through the php.net pages and gd library website, and I've asked on other forums (however nobody seems to want to help me). Code:

a way to call like a PHP file instead. For example Galley 2 (a
PHP-enabled photo album) safetly tucks away the actual images and in
the image source, it calls for something like
"main.php?g2_view=core.DownloadItem&g2_itemId=12&g2_serialNumber=3".

How do you do that? Do you need to use the database to do this?
