Remarks

Most properties and parameters that are doubles correspond to coordinates or distances in the text rendering coordinate system. In this coordinate system, x = 0.0 corresponds to the left edge of the drawing surface onto which text is rendered (x = view.ViewportLeft corresponds to the left edge of the viewport), and y = view.ViewportTop corresponds to the top edge of the viewport. The x-coordinate increases from left to right, and the y-coordinate increases from top to bottom.

The horizontal and vertical axes of the view behave differently. When the text in the view is formatted, only the visible lines are formatted. As a result, a viewport cannot be scrolled horizontally and vertically in the same way.

A viewport is scrolled horizontally by changing the left coordinate of the viewport so that it moves with respect to the drawing surface.

A view can be scrolled vertically only by performing a new layout.

Doing a layout in the view may cause the ViewportTop property of the view to change. For example, scrolling down one line will not translate any of the visible lines. Instead it will simply change the view's ViewportTop property (causing the lines to move on the screen even though their y-coordinates have not changed).

Distances in the text rendering coordinate system correspond to logical pixels. If the text rendering surface is displayed without any scaling transform, then 1 unit in the text rendering coordinate system corresponds to one pixel on the display.

Constructors

TextBounds(Double, Double, Double, Double, Double, Double)

Initializes a new instance of TextBounds.

Properties

Bottom	Gets the position of the bottom edge of the rectangle in the text rendering coordinate system.
Height	Gets the distance between the top and bottom edges of the rectangle in the text rendering coordinate system.
IsRightToLeft	Returns true if the bounds correspond to a right to left character
Leading	Gets the position of the leading edge of the rectangle in the text rendering coordinate system.
Left	Gets the position of the left edge of the rectangle in the text rendering coordinate system.
Right	Gets the position of the right edge of the rectangle in the text rendering coordinate system.
TextBottom	Gets the bottom of the text on the line containing the characters.
TextHeight	Gets the height of the text on the line containing the characters.
TextTop	Gets the top of the text on the line containing the text.
Top	Gets the position of the top edge of the rectangle in the text rendering coordinate system.
Trailing	Gets the position of the trailing edge of the rectangle in the text rendering coordinate system.
Width	Gets the distance between the leading and trailing edges of the rectangle in the text rendering coordinate system.

Methods

Equals(Object)	Determines whether two TextBounds objects are the same.
GetHashCode()	Gets the hash code of the see cref="TextBounds"/> object.
ToString()	Converts the TextBounds object to a string.

Operators

Equality(TextBounds, TextBounds)	Determines whether two TextBounds objects are the same.
