## Fields

| Field | Description |
| --- | --- |
| [TYPE_IDENTITY](#TYPE_IDENTITY) | An identity transform is one in which the output coordinates are always the same as the input coordinates. If this transform is anything other than the identity transform, the type will either be the constant GENERAL_TRANSFORM or a combination of the appropriate flag bits for the various coordinate conversions that this transform performs. |
| [TYPE_TRANSLATION](#TYPE_TRANSLATION) | A translation moves the coordinates by a constant amount in x and y without changing the length or angle of vectors. |
| [TYPE_UNIFORM_SCALE](#TYPE_UNIFORM_SCALE) | A uniform scale multiplies the length of vectors by the same amount in both the x and y directions without changing the angle between vectors. This flag bit is mutually exclusive with the TypeGeneralScale flag. |
| [TYPE_GENERAL_SCALE](#TYPE_GENERAL_SCALE) | A general scale multiplies the length of vectors by different amounts in the x and y directions without changing the angle between perpendicular vectors. This flag bit is mutually exclusive with the TypeUniformScale flag. |
| [TYPE_MASK_SCALE](#TYPE_MASK_SCALE) | This constant is a bit mask for any of the scale flag bits. |
| [TYPE_FLIP](#TYPE_FLIP) | This flag bit indicates that the transform defined by this object performs a mirror image flip about some axis which changes the normally right handed coordinate system into a left handed system in addition to the conversions indicated by other flag bits. A right handed coordinate system is one where the positive X axis rotates counterclockwise to overlay the positive Y axis similar to the direction that the fingers on your right hand curl when you stare end on at your thumb. A left handed coordinate system is one where the positive X axis rotates clockwise to overlay the positive Y axis similar to the direction that the fingers on your left hand curl. There is no mathematical way to determine the angle of the original flipping or mirroring transformation since all angles of flip are identical given an appropriate adjusting rotation. NOTE: TypeFlip was added after GENERAL_TRANSFORM was in public circulation and the flag bits could no longer be conveniently renumbered without introducing binary incompatibility in outside code. |
| [TYPE_QUADRANT_ROTATION](#TYPE_QUADRANT_ROTATION) | This flag bit indicates that the transform defined by this object performs a quadrant rotation by some multiple of 90 degrees in addition to the conversions indicated by other flag bits. A rotation changes the angles of vectors by the same amount regardless of the original direction of the vector and without changing the length of the vector. This flag bit is mutually exclusive with the TypeGeneralRotation flag. |
| [TYPE_GENERAL_ROTATION](#TYPE_GENERAL_ROTATION) | This flag bit indicates that the transform defined by this object performs a rotation by an arbitrary angle in addition to the conversions indicated by other flag bits. A rotation changes the angles of vectors by the same amount regardless of the original direction of the vector and without changing the length of the vector. This flag bit is mutually exclusive with the |
| [TYPE_MASK_ROTATION](#TYPE_MASK_ROTATION) | This constant is a bit mask for any of the rotation flag bits. |
| [TYPE_GENERAL_TRANSFORM](#TYPE_GENERAL_TRANSFORM) | This constant indicates that the transform defined by this object performs an arbitrary conversion of the input coordinates. If this transform can be classified by any of the above constants, the type will either be the constant TypeIdentity or a combination of the appropriate flag bits for the various coordinate conversions that this transform performs. |
