Create an image using php Why are you creating an image in php? There are many uses for using PHP code to create an image, one of which is to resize an image you already have without using external software. This is useful when you give your users the authority to upload an image on your website. Not everyone can be expected to upload the same size or same type of images. PHP has a solution to that exact problem. It creates an image as per your preference from the user uploaded image. Create an image using php Example: Here, we will create a smiley face using PHP code. The first thing we need to add is a header that states "Content-Type" as "PNG" image.
header("Content-type: image/png");
Now we can use imagecreatetruecolor function to create an image and give it width of 300 and height of 200. Also to publish the image, we use imagepng function because the image we are making is PNG type. You can change it to jpeg, gif or any other image format if needed. but you will have to modify the header as well.
$image = imagecreatetruecolor(300, 200); imagepng($image);
Some other functions we use in the code imagecolorallocate : assign a color imagefill : fill the image with color imagefilledellipse : create a filled circle imagefilledarc : create a filled arc imagestring : draw a word; formats imagecolorallocate(target image, Red, Green, Blue); imagefill(target image, x position, y position, color); imagefilledellipse(target image, x position, y position, width, height, color); imagefilledarc(target image, x position, y position, width, height, starting angle, ending angle, color, Type of arc); imagestring(target image, font size, x position, y position, Text, color); RGB Red, Green, Blue color codes can be 0-255, X, Y positions can be any number but exceeding the Target image's width and height will be out of bounds, angle can be 0-360, color can be added by using imagecolorallocate function, Type of arc can be 1-5, and font size can be 1-5. Instead of trying to learn these functions, copy and paste the code from below and try experimenting with it by changing its values. You can understand it quickly. Here is the full code
header("Content-type: image/png"); $image = imagecreatetruecolor(300, 200); $bg = imagecolorallocate($image, 255, 255, 255); $color1 = imagecolorallocate($image, 0,0,255); $color2 = imagecolorallocate($image, 255, 0, 0); imagefill($image, 0, 0, $bg); imagefilledellipse($image, 150, 100, 150, 150, $color2); imagefilledellipse($image, 110, 90, 20, 20, $bg); imagefilledellipse($image, 180, 90, 20, 20, $bg); imagefilledarc($image, 150, 130, 50, 50, -20, 200, $bg, 4); imagestring($image, 5, 130, 180, "hello", $color1); imagepng($image); imagedestroy($image);
