Grid snapping

Grid snapping is easy to explain. It simply means that the mouse position is rounded to the nearest grid point. Grid points are points whose coordinates are integer multiples of the grid size, which can be set in the box in the Snap field. You have a choice from a set of possible grid sizes. The units are Postscript points (in LaTeX called bp), which are equal to 1/72 of an inch. (You can actually define the set of possible choices in the configuration file).

You can ask Ipe to show the grid points by selecting the function grid visible from the misc menu. The same function turns it off again.

You request Ipe to snap to the nearest grid point by setting the button labeled + to on. Note that the +-sign resembles the orthogonal grid lattice.
