croppa
======
Crop images
usage
-----
```
croppa: --input <input.png> --output <output.png> --x <x> --y <y> --width <width> --height <height>
options:
--dx <dx> (default: width)
--dy <dy> (default: height)
--rows <num rows> (default: 1)
--cols <num columns> (default: 1)
--verbose
--verbose
```
Crop will extract one or more images from a master image.
mandatory arguments
-------------------
**--input** &lt;input.png>
Specify the filename of the image to be resized.
**--output** &lt;output.png>
Specify the filename of the resized image file.
**--width** &lt;width>
Specify the width of the crop area in pixels.
**--height** &lt;height>
Specify the height of the crop area in pixels.
**--x** &lt;x>
Specify the x coordinate for the start of the crop in pixels.
**--y** &lt;x>
Specify the y coordinate for the start of the crop in pixels.
options
-------
**--dx &lt;dx>**
Specify the number of pixels added to x after each crop
**--dy &lt;dy>**
Specify the number of pixels added to y after each crop
**--rows &lt;rows>**
Specify the number rows of images that will be cropped (total number of images will be rows*cols)
**--colss &lt;cols>**
Specify the number columns of images that will be cropped (total number of images will be rows*cols)
**--verbose**
