- All Implemented Interfaces:
- Streamable
public class PresentationTextDescriptor
- extends AbstractDescriptor
The Presentation Text Descriptor specifies the units of measure for the
Presentation Text object space, the size of the Presentation Text object
space, and the initial values for modal parameters, called initial text
conditions. Initial values not provided are defaulted by the controlling
environment or the receiving device.
The Presentation Text Descriptor provides the following initial values:
- Unit base
- Xp-units per unit base
- Yp-units per unit base
- Xp-extent of the presentation space
- Yp-extent of the presentation space
- Initial text conditions.
The initial text conditions are values provided by the Presentation Text
Descriptor to initialize the modal parameters of the control sequences.
Modal control sequences typically are characterized by the word set in
the name of the control sequence. Modal parameters are identified as such
in their semantic descriptions.
