PdfSignatureAppearanceTextBoundsAlignment Property

Gets or sets the two numbers that shall be between 0.0 and 1.0 indicating the fraction of leftover space to allocate at the left and bottom of the signature appearance text bounds.

A value of (0.0, 0.0) shall position the signature appearance text bounds at the bottom-left corner of the annotation rectangle.

A value of (0.5, 0.5) shall center it within the rectangle.

If FontSize is 0 or if ShrinkTextOnOverflow is true and the signature appearance text overflows then the scaled signature appearance text might allocate the entire leftover space at the left or at the bottom (or both) of the signature appearance text bounds and the alignment specified in that direction won't have any effect.

Default value: (0, 1). This positions the signature appearance text bounds at the top-left corner of the annotation rectangle.
