Properties

FontFile

A TrueType/OpenType font program to embed for the appearance text. null renders in standard Helvetica, which carries the WinAnsi repertoire only (Western-European scripts); characters beyond it degrade to ?. Supply a font for Cyrillic, Greek, CJK, or any other script. Complex shaping (Arabic joining, Indic conjuncts) is not performed; those scripts render glyph by glyph.

FontSize

Text size in points, or 0 (the default) to auto-fit the rectangle.

Image

A drawn mark (a handwritten signature stroke, a stamp) rendered inside the field: it aspect-fits the left slot beside the text, or the whole rectangle when Lines resolves to no text. Transparency is honored. null for a text-only appearance.

ImageBgra

The raw form of Image for hosts that already hold pixels (a browser canvas, a capture buffer): top-down BGRA, stride = width * 4. Used when Image is null; prefer Image when an ImageBuffer is at hand.

ImageHeight

Pixel height of ImageBgra.

ImageWidth

Pixel width of ImageBgra.

Layout

Where the drawn mark sits relative to the lines. Default: Beside. Without a mark, or without lines, the layout makes no difference.

Lines

The text, one entry per line. Empty composes the automatic lines (who signed, when, why) while still honoring the other appearance settings; use None for a field that renders nothing.

None

A visible field that renders nothing (an empty rectangle).

TextColor

Text color as 0xRRGGBB. Default: near-black.
