Hi all,
I have asked this before, but since I have not got it working yet, I
will ask again.
I am using a OMScalingRaster to display a depth colored layer.
(
http://labba.smhi.se/seatrack user openmap, passwd openmap)
The depth layer does not seem to center around the same point each time
you zoom or pan.
It looks like the depth layer moves a bit compared to the coastline and
other layers.
This from the source file of OMScalingRaster
* This is an extension to OMRaster that automatically scales itelf to
* match the current projection. It is only lat/lon based, and takes
* the coordinates of the upper left and lower right corners of the
* image. It does straight scaling - it does not force the image
* projection to match the map projection! So, your mileage may vary
* - you have to understand the projection of the image, and know how
* it fits the projection type of the map. Of course, at larger
* scales, it might not matter so much.
But what does this mean ? 'Understand the projection of the image'
What should I look for ?
