Creating an image
If you want to create an image then firstly you have to call canvas method. By passing height, width of the image as arguments. The colorization can be done in this method if you want to give the background color of the image then it is also possible to pass it as an argument.
- Canvas(xx,xx,'#xx')
- Canvas(height, width, '#background color')
Background color of the image is optional.
Usage:
$img = Image::canvas(800, 600, '#ccc');
Reading of image
Invention of laravel 5 makes it easier to read an image. Now you do not have to do any complicated or annoying work to read an image. For this you have to call the make function and provide the path of the image where the image is stored.
- Make(‘path of the image’)
Usage:
$img = Image::make('foo/bar/baz.jpg');
