 * **Convert to Labels** - converts an **Image** layer to a **Labels** layer. This is useful for converting a binary image segmentation map to a labels layer with each segmented object denoted by its own integer. Can also be used on a **Shapes** layer.
 * **Convert to Image** - converts a **Labels** layer into an **Image** layer.
 * **Toggle visibility** - hides or shows the selected layer.
-* **Convert datatype** - converts an **Image** or **Labels** layer into int8, int16, int32, int64, uint8, uint16, uint32, or uint64 data types. The initial data type is the data type of the data itself.

 * **Make Projection** - can be used only on a layer with more than 2 dimensions, also known as a *stack*.  It creates a new layer that is a projection of the layer stack with the characteristic the user selects, reducing the number of dimensions by 1. More information about the types of projections is available [here](https://medium.com/@damiandn/an-intoduction-to-biological-image-processing-in-imagej-part-3-stacks-and-stack-projections-942aa789420f). The following projections are available:
     * **Max** - maximum intensity projection. At each pixel position, we go  through the stacks, find the pixel with the maximum intensity, and that becomes the intensity of that pixel value in the projected image.
    * **Min** - minimum intensity projection. Similar to the maximum intensity projection, except that the minimum pixel value is used for the projected image instead of the maximum pixel value.
