I'm writing a script that will upload a file from user input, resize it to a thumbnail and add the two new filenames to a database. However, I cannot for the life of me figure out how to get PHP to detect the image's MIME type and then give it to the header. Here is the code, I've put comments to try and make it as clear as possible: $picture = $_FILES['picture']['name']; /*original file location*/ $file = 'picture/'.$picture.''; /*save thumbnail location*/ $save = 'thumb/tn-'.$picture.''; /*append thumbnail filename with tn-*/ $thumb = 'tn-'.$picture.''; /*get original file size*/ list($width

I am looking to achieve: http://i53.tinypic.com/2gule04.jpg I have tried the answers mentioned at Curving an image that starts as a rectangle (uploaded by user), preferably using Canvas or JS Based on the answers there, I have tried pixel wise transformation which didn't work. To understand a mesh based approach, you will need a skill set of 3d-2d developer which I don't possess. I am a PHP developer and I am looking for an answer in either PHP or HTML5. I have tried number of things ranging from HTML5 canvas to splitting the image into smaller parts and then joining them however those don't

is there any way to extract words from scanned images and PDF? Is there any such library for Laravel as I want to use it for laravel.

Thanks to all of you in advance !!!! joshuamabina After doing some reading... Its possible to read text from scanned images and PDF. I too couldn't find libraries for image processing built for explicit use with laravel, but I did find PHP wrappers for the infamous OpenCV and TesseractOCR , maybe

How do these filters affect the output of imagepng() in PHP? PNG_NO_FILTER PNG_FILTER_NONE PNG_FILTER_SUB PNG_FILTER_UP PNG_FILTER_AVG PNG_FILTER_PAETH PNG_ALL_FILTERS The documentation simply says, "A special PNG filter, used by the imagepng() function" for each of them. It seems that using PNG_NO_FILTER will reduce the filesize of the output, but other than that, I am unsure as to how it is affected. Any insight would be really appreciated. According to the PNG Specifications at http://www.w3.org/TR/PNG-Filters.html The purpose of these filters is to prepare the image data for optimum

I've got the code below to pull hex values from a database and create an image of that colour. There's over a thousand values, so it's looping to create an image for them all. It seems to work fine except it just keeps overwriting the first image (0.jpg) instead of creating new ones 0.jpg, 1.jpg 2.jpg etc. Any idea where I'm going wrong? Oh yeah, I'm converting the hex to rgb in there too, that works fine. <?php require ('connect.php'); $sql = mysql_query("SELECT * FROM hex") or die(mysql_error()); while($colors = mysql_fetch_array( $sql )) { $x = 0; $imgname = $x.".jpg"; $color = $colors[

Okay, so I have two images in a file. One of them is of a t-shirt. The other is of a logo. I used CSS to style the two images so that it looks like the logo is written on the t-shirt. I merely gave the image of a logo a higher z-index in the CSS style sheet. Is there anyway that I could generate an image of both the shirt and the image combined as one using the GD library? Thanks, Lance Thiago Silveira It's possible. Sample code: // or whatever format you want to create from $shirt = imagecreatefrompng("shirt.png"); // the logo image $logo = imagecreatefrompng("logo.png"); // You need a

I'm trying to take a screenshot of full screen and save it as a png. I found a code here and modified it a bit. For the screenshot I use openGL and Glut and for the saving in png the gd library for c. All I'm getting is a black png and I can't figure out why. I searched in stackoverflow and found some posts, but unfortunately they didn't help. One of them was to use glReadBuffer( GL_FRONT); instead of glReadBuffer(GL_BACK); I tryed with both of them with no success. Here is my code: int SVimage2file(char *filename){ int width = glutGet(GLUT_SCREEN_WIDTH); int height = glutGet( GLUT_SCREEN
