TextLengthType Constants

The VtTextLengthType constants provide options for optimizing text layout for the screen or for the printer.

Constant Description
VtTextLengthTypeVirtual Choose this constant to use TrueType virtual font metrics to optimize text layout for printing. TrueType virtual font metrics may not be very accurate for text displayed on the screen. Text displayed on the screen may be a larger or smaller than the virtual metrics requested. Larger text may not fit where it is supposed to and part of a character, a whole character, or even in some cases words may be clipped.
VtTextLengthTypeDevice Choose this constant to optimize text layout for the screen. Text in charts laid out for screen display always fits correctly within its chart area. The printed text is generally a bit smaller and so the text may appear in slightly different places.
