PHP :: Create Or Resize Transparent .png - Drop Shadow

Resize Transparent PNG
I have a basic script to resize a transparent png image. Code:

$dimg = imagecreatetruecolor($newwidth, $newheight);
imagecolortransparent($dimg, imagecolorallocate($dimg,0,0,0));
imagealphablending($dimg, false);
imagecopyresampled($dimg, $simg, 0, 0, 0, 0, $newwidth, $newheight, $currwidth, $currheight);

Problem is that my nice drop shadows are lost in resize. Does anyone know how I can keep them ?

GIF Resize Resample Transparent Fill
I am currently trying to create what I would think is simple. I want to create a image.php file and have it resize a 80 x 80 image to 29 x 29 with out losing the quality. When I try to have the gif image imagefill with the color white (255,255,255) it holds up and ends with a timeout. The gif images also have the black pixels if i don't try filling.

Does anyone know a simple script to just resize a gif/jpg file? All documentation has been pretty bad so this is first time posting.

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:

Create An Auto Drop Down Box
I need to create an auto drop down box. For example I already have a list of states that are pulled from the database. When the user selects a state, a drop down box below should populate with the cities from that state. (that's where I'm having trouble)

This is a search form so the results have to reflect what city and state they chose. (along with some other criteria)

I've searched all evening for instructions on how to do this and so far I've only seen javascript that you put directly in the code. If I have all 50 states along with their related cities that's an awful lot of code to put in the page.

Isn't there a way to automatically pull the cities from the database to populate the box when the user clicks a state? I have no idea where to start to make that work.

Re-create A Drop-down Menu
I have 2 drop-down menus (1) States (2) Shows By State. how do I invoke a re-build of the Shows By State drop-down when the user requests a different state. I believe this has to be done with Javascript and I don't know Javascript. Could someone supply a small example of how this is done? I am using PHP and MySQL. Following is the PHP code for building the state drop-down menu:

<tr><td bgcolor="#EFC891" width="496" align="left"><b>Select a Show in Your
State:  

<select name="ShowState" >
<?php
$stateName=getStateName();
$stateCode=getStateCode();
for ($n=1;$n<=50;$n++)
{
$state=$stateName[$n];
$scode=$stateCode[$n];
echo "<option value='$scode'";

How Do You Create Sub Drop Down Menu?
I have been wanting to create this for my site but i am not sure how. I would appreciate if anyone could show me some example code of how it's done.

What want to do is basically, say there are 2 drop down menus on my site, one for country and one for region. Say in the country menu you select UK, i would like all the regions in the UK to show up only, and if you select another country, only the regions in that particular country will show up. I am sure you understand what i mean. I would be very grateful if someone could show us how this is done.

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.
