Hi,
I figure out my images. Does anyone have a _java script for using a image for panning. I have images set for the corners of my map. I want to use them to pan.
You can use something like this, you have to handle your width and height of your image:
alto = height, ancho = width.
function paneo(direccion,alto,ancho) {
var x,y;
var pansize = 0.75;
if(direccion == 'n') {
x = (ancho-1)/2.0;
y = 0 - (alto * pansize)/2.0;
} else if(direccion == 'nw') {
x = 0 - (ancho * pansize)/2.0;
y = 0 - (ancho * pansize)/2.0;
} else if(direccion == 'ne') {
x = (ancho-1) + (ancho * pansize)/2.0;
y = 0 - (alto * pansize)/2.0;
} else if(direccion == 's') {
x = (ancho-1)/2.0;
y = (alto-1) + (alto * pansize)/2.0;
} else if(direccion == 'sw') {
x = 0 - (ancho * pansize)/2.0;
y = (alto-1) + (alto * pansize)/2.0;
} else if(direccion == 'se') {
x = (ancho-1) + (ancho * pansize)/2.0;
y = (alto-1) + (alto * pansize)/2.0;
} else if(direccion == 'e') {
x = (ancho-1) + (ancho * pansize)/2.0;
y = (alto-1)/2.0;
} else if(direccion == 'w') {
x = 0 - (ancho * pansize)/2.0;
y = (alto-1)/2.0;
}
document.mapserv.imgxy.value = x + " " + y;
document.mapserv.submit();
}
var x,y;
var pansize = 0.75;
if(direccion == 'n') {
x = (ancho-1)/2.0;
y = 0 - (alto * pansize)/2.0;
} else if(direccion == 'nw') {
x = 0 - (ancho * pansize)/2.0;
y = 0 - (ancho * pansize)/2.0;
} else if(direccion == 'ne') {
x = (ancho-1) + (ancho * pansize)/2.0;
y = 0 - (alto * pansize)/2.0;
} else if(direccion == 's') {
x = (ancho-1)/2.0;
y = (alto-1) + (alto * pansize)/2.0;
} else if(direccion == 'sw') {
x = 0 - (ancho * pansize)/2.0;
y = (alto-1) + (alto * pansize)/2.0;
} else if(direccion == 'se') {
x = (ancho-1) + (ancho * pansize)/2.0;
y = (alto-1) + (alto * pansize)/2.0;
} else if(direccion == 'e') {
x = (ancho-1) + (ancho * pansize)/2.0;
y = (alto-1)/2.0;
} else if(direccion == 'w') {
x = 0 - (ancho * pansize)/2.0;
y = (alto-1)/2.0;
}
document.mapserv.imgxy.value = x + " " + y;
document.mapserv.submit();
}
Anyother question, is there a _java script for images to zoom-in and out?
you can use the zoomdir and the zoom values within your template, like:
<input type="hidden" name="zoom" value="-2">
<input type="hidden" name="zoomdir" value="-1">
for a zoom out., so you can use radio buttons to manage this values
One more question, I have a refresh button and pan radio button, then we I click refresh to take a layer off it moves the projective image. Why? But when I am on zoomin radio button and click refresh it acts like its panning? Why?
Thanks,
