Showing

void show ([string text = "", [bool stop = false]]) Function
Prints information about the Picture to standard output.

show() first prints the string "Showing Picture:" to standard output, followed by text, if the latter is not the empty string ("")1. Then it calls transform.show(), prints the size of shapes and labels, and the value of do_labels. Then it calls show() on each of the Shapes on shapes. Since show() is a virtual function in class Shape, the appropriate show() is called for each Shape, i.e., Point::show() for a Point, Path::show() for a Path, etc. If stop is true, execution stops and the user is requested to type <RETURN> to continue. Finally, the string "Done showing picture." is printed to standard output.

void show_transform ([string text = "Transform from Picture:"]) Function
Calls transform.show(), passing text as the argument to the latter function.


Footnotes

  1. Actually, it's printed to standard output even if it is the empty string, you just don't see it.
