rlineto

rLineTo is a command used in the Scalable Vector Graphics (SVG) format to draw a line relative to the current position. It is part of the SVG path data specification and is used to create complex shapes and graphics by defining a series of commands that move the "pen" around a coordinate system.

The syntax for rLineTo is "r l x,y", where "r" indicates that the command is relative, "l" stands for "line to", and "x,y" are the coordinates to which the line should be drawn relative to the current position. The current position is updated to the endpoint of the line after the command is executed.

rLineTo is useful for creating shapes that are defined relative to their starting point, such as polygons or stars. It can also be used in conjunction with other SVG path commands to create more complex graphics.

For example, the following SVG path data creates a simple triangle:

"M 10,10 r l 20,0 r l -10,17.32 r l -10,-17.32 z"

In this example, the "M" command moves the pen to the starting position (10,10), and the three "r l" commands draw the three sides of the triangle relative to the current position. The "z" command closes the path by drawing a line back to the starting position.

rLineTo is a versatile command that can be used in a wide range of SVG graphics, from simple shapes to complex illustrations. Its relative nature makes it particularly useful for creating graphics that need to be scaled or transformed without losing their proportions.
