Open a jpg image file using the Open Image File
command in the File Menu. If the file has been annotated previously, the path
and filename of the image will appear in the white box
(C:/Annotator20d/075.jpg). If the image file has not been previously annotated,
you will be warned that a map file cannot be opened (Cannot open Map Info:
C:/Annotator20d/076.map) This file will created automatically when you save the zMap
polygon file.
If the image has not been previously annotated, you will be
warned "Cannot open map file". This file will be created automatically when you
outline an object and then save the data. Click on a point on the border of the
object you want to annotate. A small white square appears at the point where a
polygon is started. After the polygon is started, line segments join the points
that you create as you click around the object. Complete the polygon by clicking
on the small white square. Click "OK" in the Edit Object Info Window to save or
"Cancel" to delete the object. If you save the polygon, it will be saved in the
session, but a map file will not be created until you save the zMap
polygon file.
When you start a polygon a white square must appear. If it does not, then an
object was not started. You may have to close the image file and reopen it
again.
Once a polygon is created, and before it is completed, it can be erased by
right clicking if you want to start over.
Be careful when opening an image file that the cursor does not inadvertently
start an object. If one does, be sure to Right-click it away.
When you complete the polygon it will instantly be painted
blue. Click on the blue object and the "Edit Object Info" window will appear so
you can name the
new object.
Back to top
Click on the object you have just created to open
the "Edit Object Info" window. The color of the object will change to red and
the points of the polygon will be displayed. Give the object a unique name.
Add your initials at the beginning of the "Notes" field. (This has not
been done in the images shown here.) You can add additional information in the
"Notes" space. You must Click OK on the Edit Object Info Window in order
for changes to be saved!
Individual points (vertices) in the polygon can be adusted by
holding down the Ctrl + Left mouse button while moving the point
with the cursor. You must Click OK on the Edit Object Info Window in
order for changes to be saved!
Click on the object to display the points. Place the cursor over
the point to be replicated; hold down the Alt + Left mouse button
while moving the point with the cursor. Move the white square representing the
vertex to the desired position and release the mouse button. When you move the
point, the white square representing the original point will not be visible.
However, after you click the image or hit OK, and then click on the object
again, the new vertex as well as the original one will be visible. You must
Click OK on the Edit Object Info Window in order for changes to be saved!
Back to top
You must save the polygon file before opening
another image or closing the session, otherwise, all annotations made during the
session will be lost.

The Object Name List window can be opened under
Edit window. Click on the "poly" button adjacent to an object to highlight the
respective object in the image. Object Names can be changed in this list. You
must click OK to same any edits.
Back to top
As the mouse rolls over an object in the image, the object will be
highlighted and the object name will appear in the white box above the image. If
two or more polygons overlap, the polygon on the top takes precedence. Imagine
you are looking down on the stack of polygons from above. You can determine the
relative position of the polygon in the stack in the Object Name
List, which can be opened in the Edit Menu
Back to
top
The objects created on previously opened objects can be
viewed by clicking on the arrows in the upper right hand corner. Objects from
previously viewd sections appear grey. Clicking the home icon brings back
the map file for the current image. These arrows bring back maps based on the
sequence in which they were opened NOT by the file number.
Copy an Object Map to the Current Image
An object outline created on a
previously viewed section can be copied to the current image map by right
clicking on the grey object while holding down the shift key. The
object name can then be entered in the Edit Object Info window. The Edit Object
Info window preserves data entered previously during the session. If you enter
the same object on adjacent sections you can eliminate the need to retype the
Name and Note information.
Adjusting the Postion of an Entire Object Outline
After copying an
outline from an adjacent image, you can adjust the position of the entire object
by dragging it: while holding the Shift key and the Left mouse
button, drag the object outline around with the cursor.
Back to top
Currently the
default color of line segments while annotating an object is white. This color
can be changed by selecting Choose Outlining and Fill Colors... under the
Edit menu selection. It may be especially useful to change the color from
white when annotating black and white bromide images. The fill colors of the
polygons can also be change here.
