ImageEditor is a wrapper of gd functions. Firstly, it was working only in yii-application context, but not now.

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

$image = ImageEditor::createFromFile($filename);
// or
$image = ImageEditor::createWithSize($width, $height);
// or
$image = ImageEditor::createFromResource(imagecreatetruecolor(90, 90));

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 && Zoom (don't cut image)

can minimize and maximize image:

1. zoomWidthTo(int $size) - changes proportionally image width to $size
2. zoomHeightTo(int $size) - changes proportionally image height to $size

can only minimize image:

1. decreaseWidthTo(int $size) - decreases proportionally image width to $size, if needed
2. decreaseHeightTo(int $size) - decreases proportionally image height to $size, if needed
3. decreaseTo(int $size) - decreases proportionally larger side to $size, if needed

can do everything you ask it for:

1. resize(int $width, int $height) - resizes an image to $width X $height

Crop (can cut image)

1. crop($x, $y, $x2, $y2) - cuts a rectangular piece of image
2. decreaseSide($side, int $size) - deletes a piece of image from specific side. For example, if $side=top and $size=100, 100px from top will be deleted.

Rotation && Mirroring

1. rotate($angle, $bgColor = 0) - rotates an image. True equals 90°, False equals -90°.
2. horizontalFlip() - flips an image horizontally.
3. verticalFlip() - flips an image vertically.

Manipulation:

1. appendImageTo($side, ImageEditor $appendix, int $modifiers) - appends an image ($appendix) to current image at $side (top|bottom|left|right).
2. placeImageAt($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.

Save

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