Usage

Generate a letter avatar

$letterAvatar = new LetterAvatar\LetterAvatar;

$letterAvatar
	->generate('A', 40)
	->saveAsPng('/path/to/file.png');
	
# You can pass a string, the first letter will be picked

$letterAvatar
	->generate($user->getFirstName(), 40)
	->saveAsPng('/path/to/file.png');

# If you don't specify a size, the max size will be used (240 by default)	 			

Custom font

The font used by default is Open Sans Regular from google font. If you want, you can use any TTF font by setting the font file full path like so :

$letterAvatar
    ->setFontFile('path/to/ttf_file.ttf')
    ->generate('B', 40)
    ->saveAsPng('/path/to/file.png');

Save as jpeg

$letterAvatar
	->generate('J')
	->saveAsJpeg('/path/to/file.jpg');	

Save as png

$letterAvatar
	->generate('J')
	->saveAsPng('/path/to/file.png');	

Text color

$letterAvatar
	->setTextColor([255, 0, 0])
	->generate('J')
	->saveAsJpeg('/path/to/file.jpg');	

Text shadow

$letterAvatar
	->setTextColor([255, 0, 0])
	->generate('J')
	->showTextShadow(false)
	->saveAsJpeg('/path/to/file.jpg');	

Background colors palette

$letterAvatar
	->setBackgroundColors([[255, 0, 0], [0, 255, 0], [0, 0, 255]])
	->generate('J')
	->saveAsJpeg('/path/to/file.jpg');

Using the same background color

You can chain multiple generation to keep the same background color. (Generating multiple sizes)

$letterAvatar
	->generate('J', 50)->saveAsJpeg('/path/to/50x50/file.jpg')
	->generate('J', 100)->saveAsJpeg('/path/to/100x100/file.jpg');

Reset background color

If you want you can reset background color (so that a new random one will be used) in the middle of chaining

$letterAvatar
	->generate('J', 50)->saveAsJpeg('/path/to/50x50/file.jpg')
	->generate('J', 100)->saveAsJpeg('/path/to/100x100/file.jpg')
    ->resetBackgroundColor()
    ->generate('C', 100)->saveAsJpeg('/path/to/100x100/file.jpg');
