gd

Just for the record - my first question here but hopefully not my last input in the community. But that's not why I'm here. I'm currently developing a simple system that has to generate an image with a text on it. Everthing went well until I realised that GD cannot handle UTF-8 characters like ā, č, ž, ä, ø, é and so on. To clear things up - I'm using imagettftext() Trying to solve my problem I dug into depths of google and some solutions were returned, none of them, sadly, solved my problem completely. Currently I'm using this script I found in this thread - PHP function imagettftext() and

I'm trying to get imagegrabscreen (a GD function) to work with my Apache/Vista PC. I'm using the following code: <?php $im = imagegrabscreen(); header('Content-type: image/png'); imagepng($im); imagedestroy($im); ?> At the moment I get a solid black image, the size of my secondary monitor (1024*768). I'm using Apache 2.2, runing as a service, Vista SP1 with UAC off, PHP 5.2.8 and GD (information below). I've followed the note on the imagegrabscreen page about allowing Apache access to the desktop. I've also restarted the service and the apache server. I get the same results with

I have two images I would like to merge then save to a new location. I would like the second image to be place directly below the first image. I have the following so for but the image doesn't even save. $destimg = imagecreatefromjpeg('images/myimg.jpg'); $src = imagecreatefromgif('images/second.gif'); // Copy and merge imagecopymerge($destimg, $src, 316, 100, 0, 0, 316, 100, 100); Both images have a width or 316px X 100px From the above code the $destimg should now be 316x200 but that doesn't happen. Also like it to be a new image and save to another folder. Thanks for any help. The best

I got the image like this (it's a graph): (source: kitconet.com ) I want to change the colours, so the white is black, the graph line is light blue, etc.. is it possible to achieve with GD and PHP? This will replace the white color with Gray $imgname = "test.gif"; $im = imagecreatefromgif ($imgname); $index = imagecolorclosest ( $im, 255,255,255 ); // get White COlor imagecolorset($im,$index,92,92,92); // SET NEW COLOR $imgname = "result.gif"; imagegif($im, $imgname ); // save image as gif imagedestroy($im); David Crowell I had trouble making this solution work. The image cannot be a true

I want to do the following in PHP in combination with GD. ImageMagick is not an option, unfortunately, but this seems like such a common problem that there has to be a solution, I just can't seem to find it. I want to create a PNG with a transparent background. Then I want to draw a rectangle on it, copy an image on it, and add some text. One way of doing this is as follows: $image = ImageCreateTrueColor (800, 600); imagecolortransparent ($image, 0); //0 is pure black, the default fill color imagerectangle (...); //code to copy an image imagettftext ($image, ...); imagepng ($image); This works

What's the proper way in PHP to create an image file (PNG), when I have the base64 encoding? I've been playing around with: file_put_contents('/tmp/'. $_REQUEST['id'].'.png', $_REQUEST['data']); do I need to decode? should I be using the gd library? My best guess is that you simply need to call base64_decode() on $_REQUEST['data'] before writing it to the file. That should be plenty enough :). You need to use base64_decode(). AND. Sometimes it is not sufficient. Here is all code that you need: $img = $_POST['data']; $img = str_replace('data:image/png;base64,', '', $img); $img = str_replace(' '
