Name
CRC.save() — saves a copy of the current graphics state
Synopsis
void save()
Description
save() pushes a copy of the current graphics
state onto a stack of saved graphics states. This allows you to
temporarily change the graphics state, and then restore the previous
values with a call to restore().
The graphics state of a canvas includes all the properties of the
CRC object (except for the read-only canvas
property). It also includes the transformation matrix that is the result
of calls to rotate(), scale(), and
translate(). Additionally, it includes the clipping
path, which is specified with the clip() method.
Note, however, that the current path and current position are not part
of the graphics state and are not saved by this method.
