Re: [udig-devel] problem with right-to-left languages

Thanks Jody. I am not a uDig developer, for now, and not ready to dive into the source code. So, I hope a developer in community will be able to focus on this bug, a big one actually!, and resolve it.

I skimmed over the parts in the source code which you suggested and it seems that you are right, as far as I know. Lets see what is Jesse's idea. I hope he could find some time to work on it.

It is a very interesting problem; uDig is responsible for providing the affine transform used to map clicks to map coordinates. It sounds like we need to test something (the orientation?) and produce a different affine transformation in this case?

So that code should be in ViewportModelImple I guess ... let me have a look.

The method is:

    public Coordinate pixelToWorld( int x, int y ) {

        if (!validState())

            return null;

        return ScaleUtils.pixelToWorld(x, y, getBounds(), getRenderManagerInternal()

                .getMapDisplay().getDisplaySize());

    }

The MapDisplay object is responsible for knowing about the size of the display; and anything else I guess.

So here is what I would suggest you put into a patch for Jesse to review.

- a method for MapDisplay that returns the screen "orientation"

- an additional "flip" flag for the ScaleUtils.pixelToWorld method

- add a method ScaleUtils.pixelToWorld( x, y, bounds, size, orientation )

Thanks for the quick response Jesse.
It is urgent for me and I need a workaround to this. Is it possible to, for example, not make the map editor right-to-left and let it be in its default alignment? If it would be OK, how should I do that?
Any other workarounds?

Wow amazing.  I think we might use a formatting class to construct the coordinates and as a result are affected by the locale.  Although I would never have predicted this.  I wish I could give a better answer but I never expected such behaviour.

I executed uDig using a right-to-left language (I used the option -nl fa  - fa for Persian language) and there is a big problem. I loaded a shapefile (usa_counties.shp) and tried to use "select feature" tool but it seems that coordinates are right-to-lefted too! The position box below the Map Editor shows the wrong position (mirrored position). When you click at the right side of the map editor, a feature in the left side get highlighted and selected! What is the matter?

Any help would be appreciated
