Skeletonise wrapper

This page documents the wrapper class of the Skeletonize3D plugin in BoneJ2. The plugin is used trough a wrapper instead of called directly to:

1. Place it under the Plugins>BoneJ menu entry
2. Provide custom functionality

The wrapper will call the Skeletonize3D plugin even though it still is very much in the ImageJ1 world. In the ideal case we would help @iarganda to convert the plugin into an Op, but currently we do not have the resources. This will lead into some differences in the implementation of this wrapper from the others. Details below.

BoneJ1 documentation

Skeletonise wrapper

• Menu path: Plugins>BoneJ>Skeletonise. Renamed from Skeletonise 3D in BoneJ1, because the plugin can be used for 2D images as well.
• Has a @Parameter ImagePlus because there are problems with converting Datasets with composite images, i.e. the resulting ImagePlus is not GRAY8
• No setup dialog

Messages

• If there is no input image
  • Show an error dialog
  • Abort the run
• If the input image is not 8-bit binary colour
  • Show an error dialog
  • Abort the run

Output image

• Creates an output image that shows the skeleton of the input image
• Converts the output image into type Dataset
• Does not overwrite the input image
• Output image has the same calibration as input image
• The title of the output image shall be "Skeleton of <title of input image>"

Differences from BoneJ1

• Can handle composite images
• Can handle images with a time dimension

####Future

• Since there's no setup dialog, where to put the Help-button? How to provide the help?
• If input image has an inverted LUT, the LUT of the output image must be inverted
• Usage reporting
• Write user documentation
