The cross section module is designed to visualize data along vertical and horizontal axis.
The window contains three widgets :
the preview widget on the bottom left contains a preview of the current layer (center), display settings (header) and a list of all available layers (footer),
the horizontal and vertical curve widgets (top and right) contain the cross section data.
You can select the point you want to visualize by selecting the picker mode in the preview widget header, and picking a point in the image.
You can select the layer you want to preview by choosing one in the preview widget footer.
Using this module, the save button has the following options :
LDR output : the processed output (the image currently displayed on screen) saved to a *.png file,
Cross section data : the cross section values pixel per pixel, saved to a *.csv file (this file can also be opened with Excel).
