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.

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:

Can You Define An Array Constant With Define()?
I have a list of related defines like: define( "FRUIT1", "apple" ); define( "FRUIT2", "banana" ); define( "FRUIT3", "orange" ); I'd rather keep these defined in one file only so that later when I decide to modify or add to the list I don't have to mess with all my other files. Elsewhere, I'd like to loop through the constants and be able to obtain their values. This code is fine except that printf() and echo() return the constant name not the value: $i = 1; while( defined( "FRUIT$i" ) ) { echo 'FRUIT$i' $i++; } Ideally, I could define an array constant like this: define( "FRUIT", { "apple", "banana", "orange" } ); but I don't think PHP allows this. I'd rather not define these as variables and have to mess with calling them in as global variables later, etc. Any ideas? At the very least, perhaps someone knows how to trick a function like echo() to 'echo( FRUIT1 )' rather than 'echo( "FRUIT1" )'.

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›�s�÷��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?

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.

PHP3 And Define()
I know this might be an odd question, but does PHP version 3 support the define() function? What little PHP 3 documentation I have doesn't seem to contain the function, but I would think PHP 3 would support constants. I realize that upgrading and using PHP 4 and PHP 5 would give me the define() function, but that's not what I'm looking for, just the answer to this specific question. When the manual says, "PHP 4, PHP 5" and excludes "PHP 3" it's not always accurate, as there are many functions supported by PHP 3 not listed in the current manual.

Strpos() To Define PHP SELF
I'm trying to make a script that can be placed at the top of an included file. For example if I place this script in config.php then only index.php or admin.php could include it without dying with the error. For some reason the if statement doesn't work as I had expected. Any file (eg: test.php) I include config.php into, still loads without dying. $self = $_SERVER["PHP_SELF"]; $index = strpos($self, "index.php"); $admin = strpos($self, "admin.php"); if (($index === false) ¦¦ ($admin === false)) { die ("You can't access this file directly..."); } However this works... if ($index === false) // or admin.php, either works, but only one. { die ("You can't access this file directly..."); } I've also tried doing this with index.php and admin.php in an array, and it still doesn't work as expected. I'd prefer to have the script be something like the following. Naturaly it does notwork either when having two strpos() functions. $self = $_SERVER["PHP_SELF"]; if ((!strpos($self, "index.php")) ¦¦ (!strpos($self, "admin.php"))) { die ("You can't access this file directly..."); }
