+## Crop Module (crop)
+
+This module is used to crop an image.
+
+#### Usage
+
+```js
+  sequencer.loadImage('PATH')
+           .addSteps('crop',options)
+           .run();
+```
+Where `options` is an object having the properties `x`, `y`, `w`, `h`. This diagram defines these properties:

+
+* `options.x` : 0
+* `options.y` : 0
+* `options.w` : half of image width
+* `options.h` : half of image height
+
+
+## Segmented Colormap Module (segmented-colormap)
+
+This module is used to map the pixels of the image to a segmented colormap.
+
+#### Usage
+
+```js
+  sequencer.loadImage('PATH')
+           .addSteps('segmented-colormap',options)
+           .run()
+```
+
+where `options` is an object with the property `colormap`. `options.colormap` can be:
+
+* "default" : [[0, [0, 0, 255], [38, 195, 195]], [0.5, [0, 150, 0], [255, 255, 0]], [0.75, [255, 255, 0], [255, 50, 50]]]
+
+* "greyscale" : [[0, [0, 0, 0], [255, 255, 255]], [1, [255, 255, 255], [255, 255, 255]]]
+
+* "stretched" : [[0, [0, 0, 255], [0, 0, 255]], [0.1, [0, 0, 255], [38, 195, 195]], [0.5, [0, 150, 0], [255, 255, 0]], [0.7, [255, 255, 0], [255, 50, 50]], [0.9, [255, 50, 50], [255, 50, 50]]]
+
+* "fastie" : [[0, [255, 255, 255], [0, 0, 0]], [0.167, [0, 0, 0], [255, 255, 255]], [0.33, [255, 255, 255], [0, 0, 0]], [0.5, [0, 0, 0], [140, 140, 255]], [0.55, [140, 140, 255], [0, 255, 0]], [0.63, [0, 255, 0], [255, 255, 0]], [0.75, [255, 255, 0], [255, 0, 0]], [0.95, [255, 0, 0], [255, 0, 255]]]
