[Mapserver-users] zoom using ROSA

[Debbie Pagurek]

you might want to post more of your code here so we can have a look.  Your Rosa applet needs to be within an HTML form, and the applet needs the name of this form in the INP_FORM_NAME parameter.  Your zoomin button must be named in the TB_BUTTONS parameter.

the following is an extract from a mapserver CGI application I use.
Hope it helps.

I'm still new with MapServer, only started using it a couple weeks ago.
I have downloaded ROSA and worked code from the example into my html file
My problem is when I click on the zoom button, i can draw the rectange around the area that I would like to zoom into but nothing happens

Here is a little bit of my code...

<!-- Zoom In -->
<PARAM name="TB_BUT_zoomin_IMG" value="/chilliwack/rosa/userdoc/images/icon_zoomin_1.gif">
<PARAM name="TB_BUT_zoomin_IMG_PR" value="/chilliwack/rosa/userdoc/images/icon_zoomin_2.gif">
<PARAM name="TB_BUT_zoomin_CURSOR_TYPE" value="CROSSHAIR">
<PARAM name="TB_BUT_zoomin_INPUT" value="auto_rect">
<PARAM name="TB_BUT_zoomin_NAME" value="zoomdir">
<PARAM name="TB_BUT_zoomin_VALUE" value="1">
<PARAM name="TB_BUT_zoomin_HINT" value="Zoom In">

would anyone be able to tell me something that I might be missing or something I'm doing wrong

Thanks,
Yvette
