Detailed Description

frame that represents a rectangular part of another frame

A subframe is created by specifying the master frame, the top-left pixel of the subfram within the master frame, and the direction in which the subframe extends within the master frame. ( top_left + direction - direction.direction() ) == bottom-right pixel of the subframe. The direction can point towards all four quadrants, hence the subframe can appear mirrored within the master frame.

checked_write implementation as requiredby frame

When scale == 0 checked_write will do nothing, hence the subframe will not appear in the master frame.

Implements bmptk::graphics::frame.
