ImageEditor is a wrapper of gd functions.

How to start: Create from existing file or make an empty area

$image = ImageEditor::createFromFile($filename);
// or
$image = ImageEditor::createWithSize($width, $height);

Properties:

1. width - width of image
2. height - height of image
3. resource - original gd-resource of image (you can pass it directly to image-gd functions)

Operations

Resize:

1. resize($width, $height) - resizes an image to $width X $height
2. zoomWidthTo($size) - decreases proportionally image width to $size
3. zoomHeightTo($size) - decreases proportionally image height to $size

Crop:

1. crop($x, $y, $x2, $y2) - cuts a rectangular piece of image
2. cropSide($side, $size) - changes the size of $side (top|bottom|left|right) to $size.

Manipulation:

1. appendImageTo($side, ImageEditor $appendix) - appends an image ($appendix) to current image at $side (top|bottom|left|right). Warning: Function appendImageTo is not finished!
2. placeImageAt($x, $y, ImageEditor $image) - places an image atop current image at $x X $y.
3. placeImageAtCenter(ImageEditor $image) - places an image in the center of current image.
4. rotate($angle, $bgColor) - rotates an image. Warning: Function rotate works unpredictable!

Save

saveToFile($filename, $format, $quality) - saves image to disk. Possible $format values: jpeg, png. Quality is an integer value between 0 (worst) and 100 (best).
