Re: How to find out the co-ordinates when I click on a world map(Image)?

[Sunil Tiwari]

I wld have loved to build this component and that will help me understand 
JSF in much more detail.

But I havnt developed any component yet.
The real problem is that I am working on IBM's implementation of JSF and its 
not compatible with MyFaces.

I joined this community coz this is the most happening place for JSF related 
issues.
It helps me a lot with JSF issues.

Hats off to all the people of this community who have been working to polish 
MyFaces by adding new components and
by resolving oustanding issues.

Regards,
Sunil

Ideally,

you would build an image map JSF component.

If you do that, think about donating it to MyFaces ;)

Hi,

Now I see the problem. I don't know how this can be done with JSF. I know
there are some reporting products that offer JSF compoenents. You can 
find
them here http://www.jsfcentral.com/products/index.html.
Maybe some of them are free or have a trial and you can see how they are
doing.

In my opinion, what you want cannot be done with t:graphicImage or
h:graphicImage. I mean, I saw that t:graphicImage has the usemap 
attribute
but that is only to can specify the usemap. In <AREA> tag from <MAP>, you
have to link a jsp or servlet and there to take care to set your bean
members.

<MAP NAME="jfreechart-30455.png">
<AREA SHAPE="RECT" COORDS="106,15,177,251" title="(Hits, Catalog) =
3,797,300" href="xy_chart.jsp?series=Hits&section=Catalog">
<AREA SHAPE="RECT" COORDS="204,208,275,251" title="(Hits, Checkout) =
702,959" href="xy_chart.jsp?series=Hits&section=Checkout">
<AREA SHAPE="RECT" COORDS="302,195,373,251" title="(Hits, Tracking) =
903,258" href="xy_chart.jsp?series=Hits&section=Tracking">
<AREA SHAPE="RECT" COORDS="400,208,471,251" title="(Hits, Service) =
702,013" href="xy_chart.jsp?series=Hits&section=Service">
</MAP>

Hi,

Thanx a lot for your prompt reply.
The main problem is to set specific links on every area from the image.
I need to set command links instead of html href.

There will be only one command link for the image. It shd be able to know
which part has been clicked and then I shd be able
to send it as parameter to the action method in managed bean. Here, I can
decide depending on the parameter received the next image to be displayed
on the same page.

Do you have any idea how to implement it using JSF components?

Regards,
Sunil

Hi,

You need to use usemap attribute of an img html element. Usemap attach a 
map
defined in your html to the image and that map defines different areas on
your image. The you can set specific link on every area from your image.

I sow something nice with images with map used in reports here:
http://www.jfree.org/jfreechart/index.php, Servlets, JSP.
It is about the Cewolf Project.

Unfortunatelly, I don't know a nice tool to create a map for an image.

Hope this helps,
Alin.

Hi,

I have a world map which is an image and the user can click on any of the
continent.
Once a particular continent is clicked, the world map must be replaced by
that continent's map and so on..

Now, I have one image for each continent. The problem is how to know 
which
continent was clicked upon in the world map?

Any Ideas?

Sunil
