Supported image formats
Currently the library supports JPEG and PNG.
Each supported image format has its own class in the
Opening an image
From a file
The easiest way to open a file is using the
CSD\Image\Image::fromFile method, which will guess the correct file format
from the file's extension.
$image = Image::fromFile('yourfile.jpg');
If you know the file format in advance or if the file name does not have an extension, you can use one of the specific file format classes in the same way:
$jpeg = JPEG::fromFile('yourfile.jpg');
$png = PNG::fromFile('yourfile.png');
File format classes exist for all supported file formats.
From a string
Sometimes you will have a file as a binary string, e.g. if you've stored it in a database. You can pass the file as the first argument to any of the file type classes.
$data = get_my_image(); // fetched from database etc.
$image = JPEG::fromString($data);
From a GD resource
You can load the library from a GD resource too.
// example of creating an image with GD
$gd = imagecreate(100, 100);
$jpeg = JPEG::fromResource($gd);
From a stream
If you already have a stream, e.g. an open file, you can pass the file too.
$file = fopen('...', 'r+');
$jpeg = JPEG::fromStream($file);
