An image map question requires your students to identify something in an image by
clicking the image. Image map questions are particularly useful when you want your
students
to identify a named anatomical part in an illustration or geographical feature in
a
map.
Create the image file that you want to use for your question.
Best Practice Keep the image dimensions smaller than 800 by 600 pixels
to ensure that the image is displayed in the question without
scrolling.
Click
Questions > Create.
The Question Editor opens.
In Name, type a name for the question.
In Mode, select Image Map.
In Question, type your question.
Click My Files under Page Tools.
If you have not already uploaded your image to WebAssign, use the following
steps to do so.
Click Import File.
Click Browse or
Choose File, depending on your
browser.
Navigate to the file you want to
upload.
Click Open or
Choose, depending on your
browser.
Click go.
Note Uploading a large file might take some time, especially with a slower
Internet connection.
In the My Files window, navigate to the file you want to use and select its
check box.
Set Paste location of file (selected below) as to ID
Only.
Set Destination Field to Question.
Click go.
The unique WebAssign ID number for the image is added to
Question on a new line.
Edit the line with the image ID number to add an answer placeholder string for
the image map question like the following:
<_ src="ID">
where ID is the ID number of the image you want to use.
You can move this answer placeholder string to wherever it should be
displayed in the question.
Click Redisplay.
The question and image are displayed in the Display section of the
Question Editor.
Click Coordinates below the image.
In the Coordinates window, select a shape and define the boundaries for a part
of the image that your students should click to correctly answer the question.
Note Each shape defines a single key for the answer. You can define multiple
keys to allow students to click any of several areas of the image for a
correct response.
To add a rectangular key, click rectangle. Click
the image to set the upper left point of the key. Click the image to set the
lower right point.
To add a circular key, click circle. Click the
image to set the center of the circle. Click the image at the edge of the
circle to set the radius.
To add a polygonal key, click polygon. Click the
image at each vertex of the polygon, specifying adjacent vertices
consecutively.
Click Draw Key to preview the key on your image. The
key you defined is drawn in bright green on the image, and its definition is
added to a list of Keys below the image.
If a key is not correct, select its check box and click
Remove
Selected.
Tip To fine-tune the dimensions for a key that is not quite
correct, add a new key of the same shape. Using the not-quite-correct key as
a reference, type the new coordinate values instead of clicking the image.
Repeat this step until you have defined all the keys you need for the
question.
When the keys are drawn correctly on the image, select the check boxes for the
keys you want to use and click
Add Selected Key to Answer.
The Coordinates window closes and the keys are added to
Answer.
Important
If you need to use the Coordinates window more than once to add keys to
your question, you will need to manually edit the keys in Answer to
ensure that all of the keys for each question part are listed on a
single line and are delimited with the {tab}
characters.
This is necessary because although all of the keys for a question part
must be listed on the same line, each time you click
Add Selected Key to Answer, the keys are added on
a new line.
Note
If an answer extends beyond the right side of the
Answer box, it is wrapped to the next line, but it is
still considered a single line so long as you do not press
ENTER.
If you need to manually edit the keys in
Answer, the following reference information about how
image map keys are specified might be useful:
Shape
Key
Rectangle
rect:left_x,top_y,right_x,bottom_y
Circle
circle:center_x,center_y,radius
Polygon
poly:x1,y1,x2,y2,x3,y3...
Optional: Type a Solution.
The solution helps your students understand the steps they need to take to
determine the correct answer to the question. Your assignment settings
specify when to show the solution.
Click Test/Preview to test the appearance and behavior
of the question. See Test Questions.
Click Redisplay to show certain kinds of errors in the
Display section of the Question Editor. Make any needed changes to your
question.
Optional: Click Show Additional Information and change the
question's sharing permission or add descriptive information.
By default, other instructors can use your question only if you provide
them with the question ID, and only you can edit the question or find it
in search results. To change the permission, see Share Questions With Other Instructors.
If you make your question publicly available, you might want to provide
descriptive information to help others search for it. See Add Search Metadata to Questions.
When your question displays and functions correctly, click
Save.
WebAssign assigns it a unique question ID (QID), which is displayed in
parentheses after the question name.
You can use your question in an assignment and see it in your
My Questions list only after it is saved.
