gd

问题 There are tons of links on this topic - but all have a different approach. I have a clean install of os x 10.5.6. I'm using the version of PHP that came with the OS. I have installed GD using FINK, it has installed associated packages. My question is, how do I now get GD support in PHP? (pref no macports or marc liyanage suggestions as that involves undoing the other installs of pear, mysql and php I have already done) 回答1: As Nerdling points out, PHP must be compiled with the GD extension

问题 My three concerns, tried different combos with no result, googled but little or no help -- I received two times the email,change myemail@emailserver.com to the email id to see the result.

问题 I am trying to find a way to get a border color from an image using php I have tried to use this code, but this algorathim gives me all colors in any image. <?php function colorPalette($imageFile, $numColors, $granularity = 5) { $granularity = max(1, abs((int)$granularity)); $colors = array(); $size = @getimagesize($imageFile); if($size === false) { user_error("Unable to get image size data"); return false; } $img = @imagecreatefromjpeg($imageFile); if(!$img) { user_error("Unable to open

问题 I have pieced together a PHP class to perform various image related functions using GD functions of PHP. It works great for all image types. Rotate, flip, resize, crop and to a lesser extent, watermark. All but the latter work perfectly. For example after a few changes, rotated PNG images retained their transparency whereas before they were losing that and the background turning black. Common problem, it appears. But all working now. Where I'm still getting stuck is watermarking a PNG image

问题 I want to control the display of images with the PHP GD library -- I am going to add some text to the bottom corner of it on the fly when a browser requests the image, rather than saving the text into the image. I know that I can do this: set the MIME type in the header and then call imagepng(...) with the filename to just display the image to the browser, but how would I embed it in a document? Like, <img src='somefile.php?i=1' ... /> do I just call imagepng with the filename but without

问题 So I am creating a banner generator. I will be adding text in the middle, but would like it to be exactly in the center. I know that imagettftext can be used to write onto the banner, but that won't center it. A likely solution could be to find the width of the text and then use half of it taken away from half of the banner width, but I've got no idea about how to do this. I am using PHP-GD and do not want to use anything else I will have to install. imagettftext($img, 14, 0, (468 - ((strlen(

问题 I'm trying to capture a local web page with imagegrabscreen but I only get a black screenshot. I tried almost every solution from questions here on SO and others sites and nothing works. I'm using and done the following: Windows 7 64bit Wamp 2.2a 64bit PHP 5.3.8 gd2 (version: "bundled 2.0.34 compatible") is installed and enabled. Allowed the apache service to interact with the desktop. I don't have a secondary display or anything. <?php $im = imagegrabscreen(); imagepng($im, "myscreenshot.png

问题 Ok, basically I want all images to be 170x170px squares. Thus if an image is not a square i want it to be resized, and then cropped in the middle.. I have spent numerous hours playing with this and I am getting nowhere.. I have gotten it to crop a section of the bigger image etc, but i specifically need the image to be resized, then cropped.. Any help would be greatly appreciated. // get image size of img $x = @getimagesize($img); // image width $sw = $x[0]; // image height $sh = $x[1]; if(
