    Image aspect ratio utilities.

    Install

    npm install aspectratio --save
    

    API

    var aspect = require('aspectratio');

    crop(integer width, integer height, string ratio)

    Apply a fixed aspect ratio crop without distoring the image aspect ratio.

    • integer width - original image width
    • integer height - original image height
    • string ratio - new image ratio

    The ratio must be on the following format: x:y where x and y are integers. The order of x and z does not matter and 3:4 will be treated as 4:3.

    By default #crop() will match the orientation of the original image unless a forced orientation is given on the follwing format: x:y!z where z is the orientation (v for vertical, or h for horizontal).

    Return

    This will return an Array of four values:

    1. integer x - top lef x coordinate
    2. integer y - top lef y coordinate
    3. integer width - new image width
    4. integer height - new image height

    Example

    var crop = aspect.crop(2048, 768, '4:3');
    // [512, 768, 1024, 768]

    Cropp with fixed ratio

    resize(integer x, integer y, integer maxX, integer maxY)

    Get resized height and width of an image while perserving the aspect ratio of the image.

    • integer x - original image width
    • integer y - original image height
    • integer maxX - max image width
    • integer maxY - max image height

    Return

    Returns an Array of the resized x and y values:

    • integer x - resized image width
    • integer y - resized image height
