Printed beauty is an all-season trend that seizes the runways, red-carpet events, metropolitan streets, to rural festivities. While the designers and fashion houses keep exploring blends of colors and patterns, it’s PHP (Hypertext Preprocessor), the open-source server-side scripting language that brings this printed beauty to your websites and web-pages.
Solution to Displaying Print Beauty effectively using PHP
PHP offers numerous functions and libraries that facilitate the generation and manipulation of images. The built-in GD Library of PHP is a powerful tool that is capable of creating and manipulating the format of the images as jpeg, png, gif, and wbmp.
The common issues developers encounter while attempting to display an image using PHP include incorrect paths, incompatibility of formats, and inadequate understanding of the GD Library functions. Let’s delve into understanding how we can bypass these problems to effectively display print beauty using PHP.
<?php //Create an Image from a JPEG file. $image = imagecreatefromjpeg('mypic.jpg'); //Output the image to the browser. header('Content-Type: image/jpeg'); imagejpeg($image); imagedestroy($image); ?>
PHP GD Library: Function’s explanation step by step
Every function from the GD Library in PHP utilised in the code has a specific purpose in processing the image file. They, when combined, create a superb platform for handling images.
<?php //it opens a JPEG image file for processing $image = imagecreatefromjpeg('mypic.jpg'); //This sends raw HTTP header to the client header('Content-Type: image/jpeg'); //imagejpeg function displays the image imagejpeg($image); //this function is used to free the memory associated with the image imagedestroy($image); ?>
- imagecreatefromjpeg(): This function opens up a JPEG image for further processing. It returns an image identifier representing the image obtained from the given filename.
- header(): This function sends a raw HTTP header to the client. The ‘content-type’ header is being sent in our case before outputting the image.
- imagejpeg(): This function displays the image that has been transferred via the ‘imagecreatefromjpeg()’ function.
- imagedestroy(): This function is significant from the efficiency standpoint as it frees all the memory associated with the image.
Paving way for the future: Libraries similar to GD Library in PHP
While the PHP GD Library has been a go-to solution for image processing, there are other libraries in the market that offer interesting features.
Remember, selecting a library depends on the specific demand of your project. However, to give you a headway, ImageMagick and Imagick (PHP’s native extension) are the notable ones, offering extended support for formats beyond GD Library and advanced image manipulations like distortions, noise, and even creating artistic effects.
