Members

length

Type: UINT32

The number of text positions in the text line. This includes any trailing whitespace and newline characters.

trailingWhitespaceLength

Type: UINT32

The number of whitespace positions at the end of the text line. Newline sequences are considered whitespace.

newlineLength

Type: UINT32

The number of characters in the newline sequence at the end of the text line. If the count is zero, then the text line was either wrapped or it is the end of the text.

height

Type: FLOAT

The height of the text line.

baseline

Type: FLOAT

The distance from the top of the text line to its baseline.

isTrimmed

Type: BOOL

The line is trimmed.

leadingBefore

Type: FLOAT

White space before the content of the line. This is included in the line height and baseline distances. If the line is formatted horizontally either with a uniform line spacing or with proportional line spacing, this value represents the extra space above the content.

leadingAfter

Type: FLOAT

White space after the content of the line. This is included in the height of the line. If the line is formatted horizontally either with a uniform line spacing or with proportional line spacing, this value represents the extra space below the content.
