[juergenhah]

Input parameters of the Javascript function:

• An image taken with the ionic https://capacitorjs.com/docs/apis/camera camera api
• Width of the resulting image
• height of the resulting imgae

Algorithm:

• The algorithm moves the center of the "window" specified by width and height to the center of the image. Every pixel outside of the window are not included in the resulting image.
• The resulting image has the width and height given in width and height parameters.

Output of the function

• An image cropped to the width and height
• If there are metadata in the input image, e.g. EXIF data, these are also included in the resulting image

Prerequisits

• the algorithm should be self contained
• If other npm packages are used to implement it, they have to be open source
