The obliquing angle determines the forward or backward slant of the text. The angle represents the offset from its vertical axis (90 degrees). To set the obliquing angle, use the ObliquingAngle property to change a text style or the Oblique property of a text object. The obliquing angle must be provided in radians. A positive angle denotes a lean to the right, a negative value will have 2*PI added to it to convert it to its positive equivalent.
This example creates a single-line text object then slants it 45 degrees.
