PDTS_ Pen Data Scaling
The PDTS_ data scaling units are used in the
uScale and
wPndtNew arguments of the
CreatePenData and
MetricScalePenData functions, respectively. These units are used for the
wPndts member of the
PENDATAHEADER structure. Positive xcoordinate is to the right; positive ycoordinate is
down.
The following table lists the PDTS_ values. These values cannot be combined
with the bitwiseOR operator.
Constant
 Description

PDTS_ARBITRARY
 The application has done its own scaling of the data point.

PDTS_COMPRESS2NDDERIV
 The second derivative between points is stored.

PDTS_DISPLAY
 Each logical unit is equivalent to a display pixel. Positive x is to the
right; positive y is down.

PDTS_HIENGLISH
 Each logical unit is mapped to 0.001 inch. Positive x is to the right;
positive y is down.

PDTS_HIMETRIC
 Each logical unit is mapped to 0.001 millimeter. Positive x is to the right;
positive y is down.

PDTS_LOMETRIC
 Each logical unit is mapped to 0.01 millimeter. Positive x is to the right;
positive y is down.

PDTS_STANDARDSCALE
 The standard scaling metric, equivalent to PDTS_HIENGLISH. Standard
recognizers scale to this value.

The following table lists the PDTS_ bit settings. These bit settings can be
combined using the bitwiseOR operator.
Constant
 Description

PDTS_COMPRESSED
 The data is compressed.

PDTS_NOCOLLINEAR
 All redundant points removed.

PDTS_NOEMPTYSTROKES
 All empty strokes removed.

PDTS_NOOEMDATA
 OEM data removed.

PDTS_NOPENINFO
 The PENINFO structure has been trimmed from the header.

PDTS_NOTICK
 Timing information removed.

PDTS_NOUPPOINTS
 All penup strokes removed.

PDTS_NOUSER
 User information removed.

The following table lists the PDTS_ mask values:
Constant
 Description

PDTS_COMPRESSMETHOD
 Bits encode the compression scheme that is used.

PDTS_SCALEMASK
 Mask scaling bits for hardware information.

CompactPenData and
MetricScalePenData functions in Chapter 10, "Pen Application Programming Interface Functions."
