Gets or sets the maximum text width (length) for a line of text.
Assembly: PresentationCore (in PresentationCore.dll)
Text will wrap to avoid exceeding thelimit.
Glyph alignment edges must be kept within the line count limits. Because many fonts contain glyphs that slightly overhang their alignment edges, allow at least 1/6 em (font size) margin beyond the line count requested, to leave room for such overhangs.
A zero value for line count is treated as an infinite line count.
