SetTransform(Double, Double, Double, Double, Double, Double)

Sets the transformation matrix for this element. This method accepts text transformation matrix components directly.

A transformation matrix in PDF is specified by six numbers, usually in the form of an array containing six elements. In its most general form, this array is denoted [a b c d h v]; it can represent any linear transformation from one coordinate system to another. For more information about PDF matrices please refer to section 4.2.2 'Common Transformations' in PDF Reference Manual, and to documentation for pdftron.Common.Matrix2D class.

Declaration

public void SetTransform(double a, double b, double c, double d, double h, double v)

Parameters

Type	Name	Description
System.Double	a	horizontal 'scaling' component of the new text matrix.
System.Double	b	'rotation' component of the new text matrix.
System.Double	c	'rotation' component of the new text matrix.
System.Double	d	vertical 'scaling' component of the new text matrix.
System.Double	h	horizontal translation component of the new text matrix.
System.Double	v	vertical translation component of the new text matrix.

Declaration

public void SetUCRFunct(Obj UCR)

Parameters

Type	Name	Description
Obj	UCR	SDF/Cos undercolor-removal function or name

SetWordSpacing(Double)

Sets word spacing.

Declaration

public void SetWordSpacing(double word_spacing)

Parameters

Type	Name	Description
System.Double	word_spacing	a number specified in unscaled text space units. Word spacing works the same way as character spacing, but applies only to the space character (char code 32). See Section 5.2.2 in PDF Reference Manual for details.
