[OpenLayers-Users] Layer from raster images...

[Arnd Wippermann]

Hi

As a workaround you could try with a point vectorlayer and externalGraphic.
With small images it works. 

Problem is, when the insert point is outside the viewport, then the
externalGraphic will not displayed.

Example with nine images

Betreff: [OpenLayers-Users] Layer from raster images...


Hi!

It has been a while since I got any problems with OL but this time has
unfortunately come...
Actually I am just looking for some solution for my task...
I got some images that shows the city of New York with the streets hotels
and some other objects. All this data are stored as jpg files. I have images
of N.Y. in different scales e.g. 1:1000, 1:5000 and so on... So for example
I got 9 images of N.Y in scale 1:1000, 9 images in scale 1:2000 etc... I
have also got the center point of each picture. My task is to use them all
in openlayers. But I have to:
- presents not one picture on map but many pictures in some order. I mean
like this:

1.jpg 2.jpg 3.jpg
4.jpg 5.jpg 6.jpg
7.jpg 8.jpg 9.jpg

I have to glue them together using openlayers to preset the hole map of N.Y.
- I have to change all the images when someone changes the scale (zoom) 

I was thinking about using the Image layer, but as far I know, one Image
layer does not allow to present many pictures... in url you define just the
string to url, and not the e.g table of images...

I know it is not standard question but maybe someone has any ideas... or
thoughts on this... 

Any help would be appreciated

Regards
Poul
