| ===Purpose===
| |
| Crop an image DataSet based on PlotGUI selection.
| |
|
| |
|
| ===Synopsis===
| |
| :xsub = cropimage(x)
| |
| :xsub = cropimage(x,fig)
| |
| :xsub = cropimage(x,range)
| |
| ===Description===
| |
| Crops an image using either a selection made on a PlotGUI figure or the indices provided by the user. The first input is always (x) an image dataset object.
| |
| There are three modes for cropping:
| |
|
| |
| (1) If no inputs are provided, CROPIMAGE will give a window from which the user can "Select" a region to crop to. Click on "Select", mark the region to keep, then click on "Crop" to finish the cropping.
| |
| (2) If a selection has already been made on an existing PlotGUI image, the figure number of that figure can be passed to perform an immediate crop to the selected region.
| |
| (3) A vector can be provided as (range) which gives the range of x and y pixels to use to crop the image. (range) must be in the form:
| |
| [ x_min x_max y_min y_max ]
| |
|
| |
| The output (xsub) is the cropped image. The description field contains the original pixels extracted.
