<DD>This creates an ImagePresenter object from PixMap source, bounds QDRect, color depth, compression quality, codec type,

 will be kept in the format you specify, even if that is not an optimal format for rendering.

<DL>
<DD>Sets the current image data and description. 
 If the data is specified then it may be recompressed if the format of the data is 
 not optimal for redrawing and the redraw optimised flag is set to true. If you pass in null
 for the EncodedImage argument then the application must call the setImageData (EncodedImage) method
 after this to ensure that the ImagePresenter has both required data and description.
 The data formats that are not recompressed are any known pixel format (which includes the rawCodecType),
 animation, vector or QuickDraw formats.<DD><DL>

<DL>
<DD>Returns the state of the optimisation for redraw flag. If true, then when image data is set
 the ImagePresenter may decompress the image data to a format that is optimised for performance
 at the expense of possibly greater memory usage. If false, then setting the image data will
 not decompress the image data. The default is true. Changing this flag will not alter the current
 image data format, it only effects consequent calls to the setImageData (EncodedImage, ImageDescription) calls.<DD><DL>
