问题 I'm trying to get the gd2 extension to work on a WAMP stack (Win7(x64), Apache 2.4, PHP 5.3.26) I've enabled extension=php_gd2.dll in php.ini and restarted Apache. I believe my extension directory is reachable as I'm able to load other extensions (eg., curl, mbstring, etc.,) from the same location. Oddly, php -i lists gd as enabled, but there's no mention of it in phpinfo(): gd GD Support => enabled GD Version => bundled (2.1.0 compatible) FreeType Support => enabled FreeType Linkage => with

CodeIgniter/PHP/GD2 Image Manipulation is playing up

问题 I have a website going that takes a user's uploaded image, and makes three copies - a 'full' copy to print with (downsized to 1500x1125), a 'web' copy to display online (not coded yet), and finally a thumbnail. So here's the code - _imageformat() is passed the parameters (which I've confirmed to be correct) from CI's Upload Class: function _imageformat($fullpath, $shortpath, $width, $height) { // We now format the image. // First, we check if it is landscape or portrait if ($width >= $height)

people. I have slight problem with GD2 text on image. I have everything working and now i try to add text on image that can wrap within image. For example i have image with width 200px and large block of text. If you use imagettftext() text goes beyond borders of image and only partial text actually is visible. I have tried to use Zend's text wrap function, but it's not always producing accurate results here(not saying it don't work, only not in this case). Is there some dedicated GD2 method to set some width box where text should fit and if it hits border of that box it should continue in new

问题 I have a database with a column filled with image binaries data. After I made some research I figuried out how to detect in which image format is the data. Lets say in of the records in my images column is in gif format, now I want to save it with php gd2 to jpeg format. Please, can someone tell me how can I do that? 回答1: If you only want to convert the image data to JPEG then all you need is imagecreatefromstring and imagejpeg. Basically: imagejpeg(imagecreatefromstring($gif_bindata), "temp

I had been using the image resize class written by someone else to resize images or to create the thumbnails, here is the link to the class I had been using. http://www.white-hat-web-design.co.uk/articles/php-image-resizing.php I guess image GD library has some limitations for the resolution or the file size of images, it works fine for low resolution picture resizing(below 1024px) but it does not resize if I try to upload the high resolution jpeg image (i.e 3400px X 2200px) roughly, The purpose for resizing the image is i am developing a picture gallery application. Is there any way I could

I have developed a photo sharing community site using CodeIgniter 1.7. Photos that are uploaded by members are automatically resized in a number of formats, for which I use the CodeIgniter Image Manipulation class. This class is built into the framework and basically a wrapper around multiple image manipulation libraries, such as GD, GD2, ImageMagick, and NETPBM. On my host, I can only make use of GD2, so that's where this question will be about. On to my problem. Here is an example of a resized photo on my site. Note that the original was very large, over 3000px wide: http://www.jungledragon

Convert SVG image to PNG with PHP

问题 I\'m working on a web project that involves a dynamically generated map of the US coloring different states based on a set of data. This SVG file gives me a good blank map of the US and is very easy to change the color of each state. The difficulty is that IE browsers don\'t support SVG so in order for me to use the handy syntax the svg offers, I\'ll need to convert it to a JPG. Ideally, I\'d like to do this with only the GD2 library but could also use ImageMagick. I have absolutely no clue
