Help for the Coordinates Panel
************************************
"Region in Complex Plane" SubPanel
This SubPanel displays a pair of (x,y) image coordinates in the top two
numeric fields, along with the dimensions of the image (Width x Height)
in the lower pair of numeric fields. These image coordinates are in the
Complex Plane (see the User's Manual).
"LL Corner" Menu Button
This Menu Button provides 2 choices for the location of these (x,y)
coordinates:
a) the Lower left Corner of the image;
b) the Center of the image.
The user can type in values which will then be used to compute
the new image (when Apply is pressed). This is usually only done
if the user has been given the exact coordinates of someone else's
image.
"Respect Aspect Ratio" Toggle Button (Down is ON, Up is OFF)
If the "Respect Aspect Ratio" is ON (default), the user can
only enter the Width of the Width & Height values, since the
Height will automatically be recomputed to maintain the currently
specified aspect ratio of the image. If this Toggle is OFF,
both values are accepted and the image rectangle thus specified
is mapped into the full image region on the screen, with whatever
distortion in x or y may be necessary.
"Apply" Button
No changes take affect until this button is selected.
"Close" Button
Closes this Dialog Box.
"Help" Button
Displays this text window.
