Hi Group,
First, let me please explain that can not provide a map page link -
the page in question is can not be made publicly available as it would
require giving uber-account access to the world on our site, something
I can not do ;(
Abstracting the code to a stand-alone page is not really an option
either, as a lot of the page is dynamically generated.
I am trying to place a map overlay but keep it's proportion with the
original image.
The original code drew a rectangle inline of the map container
boundries around a GGroundOverlay - this is working perfectly, but I
need to try and maintain the aspect ratio of the groundOverlay image
itself.
The North East point is drawn first, inset from the top right corner
of the map container - this works perfectly.
The dimensions of the overlay image have already been stored in an
object (fp_dimensions) as w & h (width and height).
I convert the North East point position to pixels, which gives me
extreamly high numbers, not what I was expecting:
x: 18108180
y: 11363591
>From this I minus the width and height of the groundOverlay image
I convert these values back to lat/lng
And place the South East positioning handle - which ends up a long way
from where it should be, top right of the map.
My apologies again for posting a code snippet, flame me please if you
feel the need, but here goes:
function fitFloorPlanToMap()
{
marker_NE.setPoint( padBounds( map.getBounds(), true ).getNorthEast
() );
var NE_pixels = map.getCurrentMapType().getProjection
().fromLatLngToPixel(new GLatLng(marker_NE.getPoint().lat(),
marker_NE.getPoint().lng()), map.getZoom());
//add image width to it in pixels
var fixed_image_ratio_w = NE_pixels.x - fp_dimensions.w;
//add image height to it in pixels
var fixed_image_ratio_h = NE_pixels.y + fp_dimensions.h;
console.log(NE_pixels.x - fp_dimensions.w, NE_pixels.x,
fp_dimensions.w);
console.log(NE_pixels.y - fp_dimensions.h, NE_pixels.y,
fp_dimensions.h);
//convert this back to lat
var SW_latlng = map.getCurrentMapType().getProjection
().fromPixelToLatLng(new GLatLng(fixed_image_ratio_w,
fixed_image_ratio_h), map.getZoom());
//use this coord for bottom right point
marker_SW.setPoint( SW_latlng );
console.log( SW_latlng );
updatePolyline();
}
Can anybody please see what I am doing wrong?
I am sure that when I am converting the North East point lat/lng to
pixels I am not being returned the correct values, but I can not for
the life of me see why???
Any help much appreciated
Thanks in advance
Jamie
