A little background I am attempting to migrate a project built with Symfony 1.2 from one server to another. One of the functions of the project is to build a graph (originally done with JpGraph 2.3.5). The graph does not display as intended without modifications to the code and am looking for some insight on what I might be overlooking. Images are linked due to not having enough points to post. Graph Image Gallery The following graph is what is generated by the code block below <?php public function Graph($section) { $report = $section->getReport(); $this->crews = array(); foreach ($section-

I'm currently working on a script that shows thumbnails from a website on a mobile app, and I'm having problems with the "retina display". If the original image is big enough, I show a thumbnail with the double of the required size, and if it is not, I show it on the required size. Now, my function checks if it can be resized proportionally and if it can't, I resize it to the "min-width" or "min-height" and crop it from the center. Here is the problem: if it detects that the image can't be shown on the double of size, "scale up" the cropped size until it reaches the limits of the original size

I'm going to write a function for thumbnail creation. I can use both Imagemagick & GD Library methods. Which method creates better thumbnails and is faster and better for server (load, ...)? Thanks $im = imagecreatefromjpeg('photo.jpg'); $ox = imagesx($im); $oy = imagesy($im); $nx = 320; $ny = 240; $nm = imagecreatetruecolor($nx, $ny); imagecopyresized($nm,$im,0,0,0,0,$nx,$ny,$ox,$oy); imagejpeg($nm, 't_photo.jpg'); VS exec('convert photo.jpg -resize 320x240 t_photo.jpg'); What do you think? Also every good thumbnail should be sharpened a bit... exec('convert photo.jpg -resize 320x240 -unsharp

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 setting the headers? Also, if someone copies the image source out of the source code and navigates to it

When trying to save a thumbnail made with GD imagejpeg($tnImage, "../../img/thumbs/".$maxWidth."x".$maxHeight."_".$filename); I am getting the following error: Warning : imagejpeg() [function.imagejpeg]: Unable to open '../../img/thumbs/80x80_55865-drops.jpg' for writing: No such file or directory in /home/user/workspace/stewart/server-side/libImg.php /home/user/workspace/img/thumbs has its permissions set to 0x777. What can be wrong here? Where are you running the file from? If it's from the server-side directory then I think you're missing a "../" Try this: var_dump(realpath("../../img

I try to render gradient on top of an image it need to be from full color to transparent, here is my code. I get black image and if I put start more then 0 I got white gradient but no image. the output image is 338x100 px but the input image need to be aligned to right if the image is narrower. function hex2rgb($hex) { $rgb[0] = hexdec(substr($hex, 0, 2)); $rgb[1] = hexdec(substr($hex, 2, 2)); $rgb[2] = hexdec(substr($hex, 4, 2)); return $rgb; } function int2rgb($color) { $result[] = ($color >> 16) & 0xFF; $result[] = ($color >> 8) & 0xFF; $result[] = $color & 0xFF; return $result; } if (isset
