JPEGAction is a Component which makes several changes on a
Jpeg-Image. It capsules many actions which have been implemented in the
JPEGTran program.

JPEGAction as well as JPEGImage are based on the work of
NOMSSI NZALI Jacques H. C., author of the PASJPEG library
(http://www.tu-chemnitz.de/~nomssi/pub/pasjpeg.zip).

was a great help and serveral units where the basic for the JpegAction
component.

Using:    Drop the Component on your form an wire a TImage-Component
          to the Image property. (The image should contain a JPeg Graphic
          in the Picture-Property).

          After you call the 'excute' method, all actions subscribed
          in the JpegAction component will be done to your image-component.

          If a Filename is submitted in the JpegAction-component, the new
          Jpeg-Image will be saved to the respective filename.

Actions:  The property action subscribes the different kinds of transformation
          as discribed in 'JXForm_Code' in the unit TRANSUPP.PAS.
          The property ForceGrayScale transfers your colored image to a
          grayscale picture.
          The OptimizeCoding property optimizes the entropy encoding params
          (smaller file, but slow compression)
          The Progressive property creates a progressive JPEG file.
          The trimm_off_partial_edge_MCUs property trims of any partial
          edge MCUs which the transform can't handle.
