Help Cropping image

[stone419]

Hello, how do I crop an image, for example, from this kind of picture? I want to build an app in which later this cropped image would be used for dragging it to 10x10 grid table. Maybe there is some other way to do this?

Using a PC program like Adobe Photoshop or Corel Draw

Yes, but only in a square form. Not sure about Adobe Photoshop Mobile
