NAME

DoTextExpFactor − Create a text expansion factor primitive attribute object

SYNOPSIS

C:

DtObject DoTextExpFactor(textexp)
DtReal textexp;

FORTRAN:

INTEGER∗4 DOTEF(TXEXP)
REAL∗8 TXEXP

DESCRIPTION

DoTextExpFactor creates a text expansion factor primitive attribute object.  The parameter textexp specifies a scale factor for the character width such that the character aspect ratio deviates from that indicated by the font designer by textexp.  Possible values are:

0.0 < textexp < 1.0
The character width contracts by the specified amount.

textexp >= 1.0
The character width expands by the specified amount.

DEFAULTS

The default DoTextExpFactor is 1.0. 

ERRORS

The results of the text expansion are undefined when textexp is less than or equal to 0.0. 

[WARNING - value out of range]
