SvgTextData contains the following:

Member Value
Text

The text as a string. The number of items in the arrays below is equivalent to the number of characters in this string (System.String.Length).

Bounds

An array of Leadtools.LeadRectD that specifies the physical (pixel) bounds of each character in the text.

CharacterFlags

An array of SvgTextCharacterFlags that specifies the position flags of each character in the text.

Directions

An array of SvgCharacterDirection that specifies the direction of each character in the text.

OcrZoneIndex

Index of the OCR zone containing the text if this SVG document was obtained through OCR.

OcrCharacterIndex

Index of the first OCR character in the text if this SVG document was obtained through OCR.
