Sig Comp Step-by-Step
Step One Every script starts with a header..this tells the server what type of image we are making. My image for this lesson is a gif so the header and the output will be gif. <?php //DEFINE CONTENT TYPE Header("Content-type: image/gif"); The first thing we need to do is to "Import" an image into the script. //IMPORT CANVAS $im= imagecreatefromGif('http://www.wormworks.org/king/deco/chairs/chair-purp.gif'); This is how we output the image. //SHOW IMAGE OUTPUT AS GIF Imagegif($im); This will output the image into your FileManager. Remove the double slash to do this. And then change the output image name or number to prevent override. //Imagegif($im, ('LoungeLiz-1.gif')); This tells the server that we're finished with the image for now. imagedestroy($im); ?> Here is the code. Transload/upload the page to your server, copy and change txt to php. View it. You'll see my chosen gif. Now go get your gif or jpg or picture; go into edit and put its URL where mine is. Be careful of punctuation, and just before the URL you'll see ImagecreatefromGif; if yours is a jpg; change it to imagecreatefromJpeg; with the "e". The header and output should also be changed to jpeg where it says gif. Page Two
