Transparent .png
This isn't totally related to php, but I am using a php generated page that is using transparent .png's.
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?

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›�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.

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 ?

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

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?

Imagegettftext Transparent Holes
I created an image, made it transparent, drew a rounded rectangle on it and then wrote on it with imagegettftext - where the text is there are transparent holes. $image = imageCreateTrueColor($width,$height); imageSaveAlpha($image, true); ImageAlphaBlending($image, false); $transparentColor = imagecolorallocatealpha($image, 255-$r, 255-$g, 255-$b, 127); imagefill($image, 0, 0, $transparentColor); $background = imagecolorallocate($image, $br, $bg, $bb); .......

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.

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:

Transparent Text On Image?
Is it possible to place transparent text on an image? I want to display an image of some text in a fancy typeface, but superimpose text in a plain style, so that it can be copied and pasted; a bit like what you see in some PDF files, where the page image is visiable, the overlying text is not.

Transparent Filled Polygon
I'm working on a map program where each building is clickable and when it's clicked the page is refreshed to show a map with the building highlighted (in red). I was wondering if it would be possible to highlight the buildings using some sort of combination of the imagepolygonfill function and a transparency function (i'd like the buildings to still be visible under the highlight), rather than having to create many different files with the different buildings highlighted.

Make A Colour Transparent
I would like to do is grab an image, determine what colour is at a certain pixel (maybe 10, 10) and then set that colour to transparent for the whole image. Basically it is so that I can dynamically place an image on various backgrounds for previewing. I am not worried about perfection (anit-aliasing, matte, etc).

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.

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.

Creating Image From Uploaded Image And Transparent PNG
Say the client wants to be able to change the image, but not the text treatment, and doesn't have the Photoshop knowledge to actually replace it and re-save it themself. Is there anyway to use a PNG with the rounded edges, text treatment, and transparent center, have the client upload a standard rectangular-shaped image, and use PHP to layer the uploaded image underneath the transparent one, creating a new image file?
