Zoom
----
You may control the size of the image being annotated by passing a *zoom*
parameter (floating point number within the range ``]0,+inf[``). A zoom of
``1.0`` (the default), displays images as they are. A zoom larger than ``1.0``
upscales the input image making it look bigger than they originally are. A
zoom factor smaller than ``1.0`` does the inverse, scaling down the input
image. Annotations recorded on the image are *independent* of the zoom factor
and compensated upon saving operations. You can start annotating an image with
a zoom factor of ``1.0``, quit the program and then resume with a different
zoom factor. To change the zoom factor, use the ``--zoom`` parameter of the
annotator app, while starting the application. For example, to start the
application with a zoom factor of ``2.0`` do:

resizing the drawing window. The higher the zoom factor, the more precise
will be your annotation. Conversely, the lower, the less precise.
Currently, the application does not support automatic window resizing, but
it is a feature we are planning to add.
The application supports automatic resizing of the canvas to fill all the
available application area, without distorting the image or the annotations.
Use this feature to select the largest possible annotation area (typically
by fully maximizing the annotation window), which will give you the best
possible precision.
