Create a Client Redlining Task Pane widget

[pagameba]

Create a task pane widget that allows the user to:

• create a new vector layer in the client
• digitize points, lines and polygons on the layer
• save the layer as a GML file
• upload a previously saved GML file

[jbirch]

It would be useful to be able to persist the vector layer on the server. In MapGuide, this would be as data+layerdefinition; not sure how this would work in MapServer.

Will it be possible to style the vector layer? Are you planning to persist the styling information in the GML?

Will it be possible to "render" the vector layer so that it can be printed? For my users, printing (to paper or pdf) would be one of the primary use cases for redlining.

I have made and committed the first prototype of the redlining widget in r1832. For future enhancement, i will let Paul or Mike answer. For the moment, there is no persistent layer on the server. We can only save/upload a GML file. The styling information is not saved in the GML neither.

• ApplicationDefinition extension:
  • TaskPane: the id of the html element to plate the task pane
  • DefaultControl: the default control that should be activated
  • UploadDirectory: the upload directory where the uploaded files are saved. That directory have to be accessible from the web Default is "/uploads/" (see also upload.php)
  • FeatureStyle: the default feature style. You can put any feature style property here. The properties will be add to the OpenLayers.Style object. ie:

     <Widget xsi:type="UiWidgetType">
       <Name>toolbarRedline</Name>
       <Type>Redline</Type>
       <StatusItem>Digitizing tool</StatusItem>
       <Extension xsi:type="CustomContentType">
         <Target>TaskPane</Target>
         <FeatureStyle>
           <fillColor>#0f0Ff0</fillColor>
           <strokeColor>#0133F1</strokeColor>
           <strokeWidth>5</strokeWidth>
         </FeatureStyle>
         <UploadDirectory>/uploads/</UploadDirectory>
         <DefaultControl>Rectangle</DefaultControl>
       </Extension>
       <ImageUrl>images/icons.png</ImageUrl>
       <ImageClass>Digitize</ImageClass>
       <Tooltip>Digitize</Tooltip>
       <Label>Digitize</Label>
       <Disabled/>
     </Widget>
    

NOTE: the defaultFeatureStyle property of the widget should be modified.

(In [1842]) re #251, some Google support changes to make it possible to overlay stuff.

[pagameba]

opps, that comment should have been in #252 ...

[pagameba]

(In [1850]) re #251, update OpenLayers.js to include the required capabilities for redlining and modify redline task pane code to use timeout instead of interval as the interval was never clearing for me.

[pagameba]

(In [1851]) re #251, adding widget info file.

[pagameba]

(In [1852]) re #251, wrong default icon

[pagameba]

closing fixed, any problems can be reported as new bugs.
