Enum Class AffineTransformType

java.lang.Object
java.lang.Enum<AffineTransformType>
net.paulhertz.pixelaudio.AffineTransformType
All Implemented Interfaces:
Serializable, Comparable<AffineTransformType>, Constable
public enum AffineTransformType extends Enum<AffineTransformType>

The AffineTransformType enum defines the types of affine transformations that can be applied to bitmaps in the PixelAudio library using only rotation and reflection. PixelMapGen uses the AffineTransformType enum to specify the type of transformation to apply to the gen coordinates and LUTs. PixelMapGen's comments strongly suggest starting gen coordinates at (0,0) in the upper left corner, but this may vary with the signal path you want to create. The Moore curve, for example, begins at the top center of the bitmap. The BitmapTransform class applies the transformations defined in this enum to bitmaps using lookup tables.

Naming follows computer graphics conventions where 0 degrees points right and positive rotation is counterclockwise.

   NADA         no operation
   R270         rotate 90 degrees clockwise
   ROT180       rotate 180 degrees
   R90          rotate 90 degrees counterclockwise
   FLIPX        reflect on y-axis, y coordinates do not change
   FX270        reflect on y-axis, then rotate 90 clockwise = reflect on the secondary diagonal, upper left to lower right, secondary diagonal does not change
   FLIPY        reflect on x-axis, x coordinates do not change
   FX90         reflect on y-axis, then rotate 90 counterclockwise = reflect on the primary diagonal, upper right to lower left, primary diagonal does not change

      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static AffineTransformType valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null
