gd

问题 So far I have the background working, and I have the % bubble floating on top of the bar working. Everything went smoothly using the PHP/GD functions. But I can't figure out how to add the yellow part. I mean, I could overlay solid color easily. But how would I go in showing that progress bar with vertical stripes, gradients, rounded border and inner shadows? 回答1: Actually, I found an example using php , javascript , and html here, you can also use the jquery implementation here. And here is

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

问题 I'm trying to display a number using GD. This number changes, so sometimes the width needs to change. Is there a way to calculate how wide the text will be so that I can dynamically set the width? 回答1: Yes, you can find out the dimensions of a text using imagettfbbox() (or imageftbbox() if you're using Freetype). 来源： https://stackoverflow.com/questions/4485630/how-can-i-auto-adjust-the-width-of-a-gd-generated-image-to-fit-the-text

问题 I'm using Imagine to resize images after uploading them with curl in /tmp : $_imagine = new \Imagine\Gd\Imagine(); $mode = \Imagine\Image\ImageInterface::THUMBNAIL_INSET; $image = $_imagine->open($path); // i.e $path = '/tmp/photo.jpg' // then resizing the $image It is working fine with any previously uploaded images in my /tmp , but when uploading this image http://newsimg.bbc.co.uk/media/images/67373000/jpg/_67373987_09f1654a-e583-4b5f-bfc4-f05850c6d3ce.jpg then trying to open it with

问题 I am attempting to install the GD library using Strawberry perl and GnuWin32. However, when I enter "install GD" in the CPAN shell, the following message appears: 'gdlib-config' is not recognized as an internal or external command, operable program or batch file. **UNRECOVERABLE ERROR** Could not find gdlib-config in the search path. Please install libgd 2.0.28 or higher. I believe perl is having difficulty locating the GD library installed at C:\Program Files\GnuWin32\bin, but I am not sure

问题 Using the imagettftext function from the PHP GD library, one can only draw text that is left-aligned onto an image. At least so it would seem, perhaps I'm missing something.

问题 I have a case: I took a photo. Now I want to read date of the created photo (the shooting photo date) using GD. Is it possible to get this date created from the image metadata? 回答1: Use exif_read_data() function instead, you will get everything you'd need :) http://php.net/manual/en/function.exif-read-data.php Look for the particular Exif data with a key DateTimeOriginal. Make sure that the software you are using are not stripping the actual exif. For example if you are using Photoshop, doing

问题 I'm trying to create a thumbnail image for a larger image. I'm using Jcrop to get the co-ordinates of the crop but I can't turn this into a properly cropped thumbnail image. I've set up Jcrop properly and it's sending through x-y co-ordinates along with the size of the box but I can't work out how to crop from that. What I have is the path to an image on my server, along with 4 co-ordinates and the width and height of the square box they create (I've locked the aspect ratio to 1:1 as I want
