(Re-)draw a tile graphical object
Description
This internal function draws a tile graphical object to the current
device. It is mainly of use of an internal function; most users should
simply use tile to create and save tile graphics to a file.
Usage
tileDraw(grob, defaultlayer=10)
Arguments
grob |
A tile or grid graphical object; e.g., the object in the
slot grob in the value returned by tile |
defaultlayer |
The layer to draw any sub-elements of
grob. Layers with higher numbers are drawn first, then lower
numbers are drawn on top. |
Details
This internal function is provided for completeness, and is not necessary to
create tile graphics with detailed annotations, which can be done
through careful construction of a single call to tile.
However, if users wish to add to or modify an existing tile grob, they may do so by directly editing the grob returned by tile, then sending it to this function to place it on the current device. Care should be taken to set up the current device to have appropriate height, width, and pointsize.
Value
tileDraw is mainly called for the side-effect of drawing a tile
grob. It invisibly returns the grob after drawing.
