RCOR_ Tablet Orientation
RCOR_ values
are used in the wRcOrient member of the global RC structure. The RC
structure is passed to a version 1.0 recognizer in the lpRC argument of InitRC and informs the recognizer
of the tablet orientation. The recognizer can optionally use the orientation to
direct the transformation of tablet coordinates to ideal coordi-nates used for
recognition.
RCOR_
constants are provided only for compatibility with version 1.0 of the Pen API
and will not be supported in future versions.
The following
table lists the RCOR_ values:
|
Constant |
X-coordinate |
Y-coordinate |
|
RCOR_NORMAL |
X = X' |
Y = Y' |
|
RCOR_LEFT |
X = yMax -
Y' |
Y = X' |
|
RCOR_RIGHT |
X = Y' |
Y = xMax -
X' |
|
RCOR_UPSIDEDOWN |
X = xMax -
X' |
Y = yMax -
Y' |
As with the
preceding values, direction is provided as a clue to the recognizer. A
recognizer may attempt to identify the direction of writing by itself.
