7.3.5.1 Region Panel: properties

The bottom of this panel features a slider to switch between regions in the image. Regions can be removed by hovering over and pressing ESC or by pressing the buttons to the right side of the slider where the first button deletes all regions and the far right button deletes the region that is currently displayed in the panel.

The properties tab can be used to adjust the the size, center, and coordinate frame of the region (’coordinates’ selection at the top). The inputs can be in different units, and those implemented in the viewer are commonly used sub-sets of the options listed in §D. At the top of the panel, one can specify the channel range over which the region shall be defined. The ’selection’ check box is an alternative way to the SHIFT+click to select a region. The ’annotation’ checkbox will place the ’ann’ string in front of the region ascii output – annotation regions are not be used for processing in, e.g. data analysis tasks.

The second horizontal tab ’line’ brings up a panel to change the color, line width, and line style (solid, dotted, dashed) of the selected region.

The third panel, ’text’, can be used to assign a string to the region which can be controlled in position (the little dial at the bottom, and the two right hand boxes), as well as text font, style, and color.
