[OpenLayers-Users] FW: Download image(bitmap)

Sat Apr 18 15:29:17 EDT 2009

Hi,

if you only want, that the user can download your singleTiled WMS, then
inform the user, that they could save the image via right click and save as.
There is no need to download the image, because it is already there.

Otherwise you have to use serverside scripting and sending the image once
again.

Hi,

I have only one wms layer and is a single tile. I would like to make it user
friendly.

Want to have a button called 'generate bitmap' or similar.

That zip up the bitmap and send it to the user so they can view at a later
stage.

Thanks.

Hi,

if it's only one wms layer and singleTiled, then the easiest way should be
to use right click on the map and save image.

if it's not singleTiled you can try something like this:

var wmsRequest=yourWMS.getFullRequestString() + "&BBOX=" +
yourWMS.getExtent().toBBOX() + "&WIDTH=" + map.getSize().w + "&HEIGHT=" +
map.getSize().h;

window.open(wmsRequest);

it generates the WMS request for your layer as singleTile, opens it in a new
window and there you could save the image via right click.

Hi

Very sorry about the lack of information.

Yes, it's a single tile map (using the SingleTile option = true).
I am expecting exactly what the browser can see. 
In this case i am displaying a single tile jpeg image on the browser
requested through the wms service.

I do not want download the base layer. Just those layers i have
IsBaseLayer=false.
In my case. I only have 1 baselayer and 1 non-baselayer.

Thanks.
