on the screen.
|
|
|
|
This interface provides the standard mechanism for an assistive technology
|
|
to retrieve information concerning the graphical representation of an object.
|
|
Coordinates used by the functions of this interface are specified in
|
|
different coordinate systems. Their scale is the same and is equal to
|
|
that of the screen coordinate system. In other words all coordinates
|
|
are measured in pixels. They differ in their respective origin:
|
|
<ul>
|
|
<li>The screen coordinate system has its origin in the upper left
|
|
corner of the current screen.</li>
|
|
<li>The origin of the parent coordinate system is the upper left corner
|
|
of the parent's bounding box. With no parent the screen coordinate
|
|
system is used instead.</li>
|
|
</ul>
