A three-point hitch mountable to the front frame of an agricultural tractor includes a main backing member, an upper hitch-point anchor bracket having four sets of securing pin anchoring positions that is welded to the main backing member, a pair of spaced-apart pivot anchors welded to the main backing member, an A-frame assembly pivotably installed between the pivot anchors, and a hydraulic cylinder which raises and lowers the A-frame assembly operably coupled to one of the middle sets of pin anchoring positions and the A-frame assembly. An implement can be connected to the upper-most anchoring position and the distal ends of the A-frame assembly. The three-point hitch can be converted to a ball hitch by re-pinning the hydraulic cylinder to the uppermost anchoring position, raising the A-frame assembly about ninety degrees and pinning it to the anchor bracket.

An operating system software architecture, implemented in an object-oriented design, supports and processes color. The object-oriented design has two levels, one being a class (TColor) defining a virtual abstract base class and being a container class containing calibrated colors, the other being a class (TDeviceColor) defining a virtual abstract base class and a container class containing uncalibrated colors. Several calibrated color classes including a class (TXYZColor) defining XYZ color space descend directly from class (TColor), several uncalibrated color classes including a class (TRGBColor) descending directly from class (TDeviceColor), a class (TColorGamut) storing color gamut information of peripheral devices that may interface with the architecture, and a class (TColorProfile) storing tonal reproduction curves of the peripheral devices provide data structures, together with method functions for various color processing. The architecture is extensible to add new color classes as new color models and devices are developed, to add new color matching algorithms as desired, allows users to work in color space of their choice, and provides for color matching amongst any peripheral devices interfacing with the architecture.

A method and apparatus providing a polymorphic pixel buffer. An object-oriented system design provides a robust and extensible pixel specification which allows for new methods, data types, and operation to be added to a digital pixel representation and processing system.
