Class RotationMinMaxWidth

java.lang.Object

com.itextpdf.layout.minmaxwidth.MinMaxWidth

com.itextpdf.layout.minmaxwidth.RotationMinMaxWidth

All Implemented Interfaces:

Serializable

public class RotationMinMaxWidth
extends MinMaxWidth

Class for min-max-width of rotated elements. Also contains heuristic methods for it calculation based on the assumption that area of element stays the same when we try to layout it with different available width (available width is between min-width and max-width).

Constructor Detail

RotationMinMaxWidth

public RotationMinMaxWidth(double minWidth,
                           double maxWidth,
                           double minWidthOrigin,
                           double maxWidthOrigin,
                           double minWidthHeight,
                           double maxWidthHeight)

Create new instance

Parameters:

minWidth - min-width of rotated element

maxWidth - max-width of rotated element

minWidthOrigin - the width of not rotated element, that will have min-width after rotation

maxWidthOrigin - the width of not rotated element, that will have max-width after rotation

minWidthHeight - the height of rotated element, that have min-width as its rotated width

maxWidthHeight - the height of rotated element, that have min-width as its rotated width

calculate

public static RotationMinMaxWidth calculate(double angle,
                                            double area,
                                            MinMaxWidth elementMinMaxWidth)

Heuristic method, based on the assumption that area of element stays the same, when we try to layout it with different available width (available width is between min-width and max-width).

Parameters:

angle - rotation angle in radians

area - the constant area

elementMinMaxWidth - NOT rotated element min-max-width

Returns:

possible min-max-width of element after rotation

calculate

public static RotationMinMaxWidth calculate(double angle,
                                            double area,
                                            MinMaxWidth elementMinMaxWidth,
                                            double availableWidth)

Heuristic method, based on the assumption that area of element stays the same, when we try to layout it with different available width (available width is between min-width and max-width).

Parameters:

angle - rotation angle in radians

area - the constant area

elementMinMaxWidth - NOT rotated element min-max-width

availableWidth - the maximum width of area the element will occupy after rotation.

Returns:

possible min-max-width of element after rotation

calculateRotatedWidth

public static double calculateRotatedWidth(Rectangle area,
                                           double angle)

Utility method for calculating rotated width of area in a similar way to other calculations in this class.

Parameters:

area - the initial area

angle - the rotation angle in radians

Returns:

width of rotated area
