ImageCoordinatesWindow

The ImageCoordinates-Window displays informations about the
current image (the one spefied as input from within the
PCSinglePicture-Window) and allows you to modify several
effect-parameters graphically.
There a some types of controls which can be dragged and
modified using the mouse.

Functions

Control-Type     type of control:
                   point : simple point, e.g. represting a upper-left edge
                           of a image to be composed
                   rect  : e.g. representing a crop-region
                   circle: e.g. representing the amount and the radius
                                of a Twirl-effect

Left,Top         coordinates of the point (in coordiantes of the unscaled image),
                 upper-left edge of the rectangle,
                 centre of the circle,
Right, Bottom    lower-right edge of the rectangle
Angle            angle of the current drawn radius of the circle
Radius           radius of the circle
Apply            apply the settings to the currently selected effect

Currently supported PlugIns
   BlackHole   (point, circle)
   BGradient   (point, circle)
   Circle      (point, circle)
   ColorRegion (point, circle)
   Crop        (rect)
   Magnet      (point, circle)
   Rectangle   (rect)
   Rotate      (point, circle)
   RotateBlur  (point, circle)
   Twirl       (point, circle)

Notes
1) To grab a region for a Crop-effect it is necessary to disable
   the effect (pressing <n>) before opening the ImageCoordinates-Window.
   Otherwise the image shown as preview is already cropped.
   This "nasty" behaviour is a result of the clear preview-concept and
   no "bug" or similar.
2) This window can be also used to grab a color. If the control-type
   is set to "point" the original colors (i.e. of the untransformed image)
   at the current cursor-position are displayed as rgb-values.
3) Graphically specified parameters have the higher priority.
   So it makes no sense to change a parameter from within
    Parameter-Settings -Window while
   the ImageCoordinates-Window is open.
