// Class : TextPropertiesManager
|
|
// Description : This defines all of the TextProperties structures
|
|
// that might be referenced by name from an embedded
|
|
// text string.
|
|
//
|
|
// A text string, as rendered by a TextNode, can contain
|
|
// embedded references to one of the TextProperties
|
|
// defined here, by enclosing the name between \1 (ASCII
|
|
// 0x01) characters; this causes a "push" to the named
|
|
// state. All text following the closing \1 character
|
|
// will then be rendered in the new state. The next \2
|
|
// (ASCII 0x02) character will then restore the previous
|
|
// state for subsequent text.
|
|
//
|
|
// For instance, "x\1up\1n\2 + y" indicates that the
|
|
// character "x" will be rendered in the normal state,
|
|
// the character "n" will be rendered in the "up" state,
|
|
// and then " + y" will be rendered in the normal state
|
|
// again.
|
|
//
|
|
// This can also be used to define arbitrary models that
|
|
// can serve as embedded graphic images in a text
|
|
// paragraph. This works similarly; the convention is
|
|
// to create a TextGraphic that describes the graphic
|
|
// image, and then associate it here via the
|
|
// set_graphic() call. Then "\5name\5" will embed the
|
|
// named graphic.
