Class RotationMinMaxWidth

java.lang.Object
com.itextpdf.layout.minmaxwidth.MinMaxWidth
com.itextpdf.layout.minmaxwidth.RotationMinMaxWidth
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 Details

    • 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
