gd

I'm trying to download this image with PHP to edit it with GD. I found many solutions for image links, but this one is a download link. Edit: $curl = curl_init("http://minecraft.net/skin/Notch.png"); $bin = curl_exec($curl); curl_close($curl); $img = @imagecreatefromstring($bin); This is my current code. It displays "301 Moved Permanently". Are there CURLOPTs I have to set? $curl = curl_init("http://minecraft.net/skin/Notch.png"); // Moved? Fear not, we'll chase it! curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true); // Because you want the result as a string curl_setopt($curl, CURLOPT

i've been working on a webapp. i got stuck here in a problematic issue. i'll try to explain what im trying to do. here you see first big image which has green shapes in it. what i want to do is to crop those shapes into different png files and make their background transparent like the example cropped images below the big one. The first image will be uploaded by user and i want to crop into pieces like the example cropped images above.it can be done with GD library of php or by a server-side software written in python or c#. but i dunno what this operation called so i dunno what to google to

Opening a JPEG image using imagecreatefromjpeg can easily lead to fatal errors, because the memory needed exeeds the memory_limit . A .jpg file that is less than 100Kb in size can easily exceed 2000x2000 pixels - which will take about 20-25MB of memory when opened. "The same" 2000x2000px image may take up 5MB on the disk using a different compression level. So I obviously cannot use the filesize to determine if it can be opened safely. How can I determine if a file will fit in memory before opening it, so I can avoid fatal errors? According to several sources the memory needed is up to 5 bytes

I'm currently coding an uploader script based on Uploadify. Right now I resize the given image and watermark one of the sizes. It all works well, but I need the script to resize the height and then crop the width so that the aspect ratio does not get messed up. This is my code so far: if ($fileExtension == "jpg" || $fileExtension == "jpeg" || $fileExtension == "png" || $fileExtension == "gif"){ // GD variables: list($width, $height, $type) = GetImageSize($uploadedFile['tmp_name']); // Image sizes: $bigImage = array(800, 453); $mediumImage = array(410, 231); $listImage = array(120, 68);

I have been trying to troubleshoot why CPAN GD module fails to install using Cygwin for 2 days now. Any help is much appreciated.

I am trying to make very simple ISO engine in PHP, my attempts to render in correct place, order etc are succeding however the images drawn, for some reason are black where it should be transparent. PNG files have transparency channel and I am using following test code: http://pastebin.com/TXk4LkJ8 The code is just rough draft. Files are just 3 faces of an block with dimensions as follows: top - 44x22; sides:23x34 Thank you for your help and I hope the question is clear enough. Edit: Here is the problem: http://dl.dropbox.com/u/10530011/obrazki/isofail.png Edit: [ SOLVED ] For some reason I

In my old PHP apps i used to run a function like the one bellow to create jpeg image thumbnails. function imageThumbanail() { $image_src = imagecreatefromjpeg('http://examplesite.com/images/sample-image.jpg'); $thumbnail_width = 180; //Desirable thumbnail width size 180px $image_width = imagesx($image_src); //Original image width size -> 1080px $image_height = imagesy($image_src); //Original image height size -> 1080px $thumbnail_height = floor( $image_height * ( $thumb_width / $image_width ) ); //Calculate the right thumbnail height depends on given thumbnail width $virtual_image =

Does someone know if it's even possible (in PHP) to take a frame/thumbnail from a quicktime movie on the server? Something like the usual GD thumbnail generation, but for .mov files. note: I'm using dreamhost, so I don't have more than web-panel access to the server. Dreamhost provides a shared ffmpeg binary in /usr/bin/ffmpeg, so you should definitely be able to call ffmpeg from php by using the system() or shell_exec() functions. The Dreamhost wiki has also an entry providing directions on how to install and configure ffmpeg-php.. This looks promising: http://ffmpeg-php.sourceforge.net/index
