[Gvsig_english] gvSIG (build 1225): some bugs and wishes.

[Sergio Clark]

Hello Wolfgang,

I've been trying to reproduce some of these bugs, but in the actual 
release 1226. I'll make some comments about:

You're right about this. Second one we think it's related with jcrs 
extension. First one, we're trying to fix it.

> 2) Adding layers

I couldn't reproduce it. I've connected correctly to an Oracle database 
and loaded layers (remember that it's necessary to add an oracle .jar in 
order to make it work).

On the other hand, I've loaded WMS layers and it worked (I tried with a 
Nasa server and also with Spanish Catastro one)

> 3) opening projects
> * if an existing project is opened, layers are all set to mode "not visible". As reported earlier by another user, layers get labeled, although that was not defined before. If the project contains larger shapefiles this can be a big problem (as the rendering of the labels takes quite some time)...
>   

First problem doesn't happen to me, but it does second one: labeling is 
automatically enabled (but I don't see any label if I don't Apply or 
Accept the Label panel). We'll note this as a bug.

> 4) Editing layers
> * I tried to modify the attributes of a layer that contained only one element. This was nearly impossible: during editing the table, the new value in the table did not appear. Only when finishing the edit mode, changes got visible in the table. This did not happed if the layer contains more than one element.
>   

I can see the changes without 'Finishing edition', but I must close and 
reopen the table (even this way, it's a bit annoying too).


> * The new merge-tool is great. However, it happens every now and then that the former border of two polygons (that was removed during merge operation) is still visible as a very thin line. Should not be the case. Or am I wrong??
>   

I couldn't reproduce it in 1226. This part is being developped at the 
moment, so it can exist changes from build to build.

> 5) labeling layers
> * using the "individual labelin"-tool: 
>   + using "redo" to remove a new label will cause an error message to appear (use error....")
>   + typing in a value for "font rotate" > 0 will create a label that is too far away from the labeling point. This distance is variable depending to the value for "font rotate" is bigger. This is a problem, as it is not possible to minimize that distance.

Yes. We're working on solve both bugs.

> 6) Map (Layout)
> * It was not possible to create a pdf-output. Error message ("Error grave de la application....), pdf created that cannot be opened.
> * I failed in creating a template for the map layout. Error message: error grave de la aplication.

It doesn't happen to me. Could you send us the .log file?

> WISHES
> 1) Displaying data
> * layers should not be activated automatically when added to the view. This could save quite some time.
> * layers should get different colour when loaded into the view. Now, all layers are drawn in blue. Would save some time for a first glance (because currently, the user has to alter the colour of the layers before, in order to separate them visually).
>   

For the second one, you have the possibility to make this colour 
'Aleatory' by activating this option inside gvSIG 
Preferences/Symbology/"Default fill colour".

> 2) labeling
> * user defined labels - this function is really great. Sometimes - especially if the layer is a little bit bigger - it takes too long for the labels to be drawn. It would be great, if that could be made faster. Currently, it is a little bit annoying to see that the labels seem to be recalculated every time the extent of the map has been changed (by zooming in, dragging etc.). Possible?
>   
Don't know.

> * Filter expressions in the layers properties should also have an effect on displayed labels. Currently, this is not possible.
>   

I'm not sure if I've understand you. When I write a filter sentence for 
labeling only some geometries, and Apply it, I can see changes in the 
view. Is this what you mean?

> 3) Layout (Map)
> * It would be nice to have an option to keep the aspect ratio of inserted images (or other objects) when scaling them...
>
> 4) Symbols
> * It would be cool, if there where some colour schemes available with some more "pastose" colours. Is it possible to add custom colour schemes (unique values). Applying the current ones additionally produces often very similar colours for different values. Could this be changed?
> * As proposed by Ben, I would really appreciate, if there was a possibility to display charts (pie-, barcharts) also.
>   

We'll note this as feature requests.

Thanks very much for your collaboration.
