Print map sample

DominiqueBroux — Wed, 17 Nov 2010 18:45:06 GMT

For those who are interested, I just updated the print map sample.
A live version is still available here.

After refactoring the code, there are now separate components for:
- cloning a map (using an attached property)
- displaying the print grid (PrintOverviewLayer)
Combining these components gives more output possibilities just by changing the mapprinter style.
Example of output : WithLegend/WithOverview (in low definition pdf to reduce file size).

Hi Dominique,

firstly, excellent example print. I've actually used a customised version of the previous sample for some work 🙂

I did notice a couple of minor issues.
The Now property doesn't update so if you format the data to show time it's always the same.

In the CloneMap Clone method, you aren't setting the Max/Min Resolution for GraphicLayer types.

toLayer.MinimumResolution = layer.MinimumResolution;
toLayer.MaximumResolution = layer.MaximumResolution;

Also in the same method you can save some processing by only cloning visible layers
i.e. foreach (var layer in mapToClone.Layers.Where(lyr => lyr.Visible && lyr.Opacity > 0.0))

Cheers,

Hi Dave,

Thanks for your comments.

I updated the sample to take care of your remarks and to remove the 'CurrentPageFillSymbol' property (use the 'Selected' state of the 'PageFillSymbol' instead)

Thanks.

Hi Dominique,

thought I'd send my modified version in case you wanted to merge the additions. I've only attached the affected files (note that I've refactored the code to match my own coding style and I changed the namespace and deleted parts that I don't use).

The main additions are a dictionary that can be used for custom values to be output on the print. The Title property shows an example of this but I have used it in another project to insert a custom legend based on the symbols used for selections (the user could set a different symbol for each selection and then annotate that symbol for the legend). I also added 2 events, OnInitializingPrint and OnErrorPrinting. OnInitializingPrint can be used in conjunction with the dictionary described previously. OnErrorPrinting is self explanatory.

There is also a minor change in the CloneMap file.

Cheers,

Hi Dave,

Thank you very much for your additions. I will update the sample with them.

Just a question about the added dictionary: Isn't possible to get the same expected result by initializing the data context of the map printer with whatever the user wants (a dictionary being a particular case)?
Note that, I didn't really try this option, so there is possibly a blocking point somewhere:)

Hi Dominique,

yes setting the DataContext seems to work great.

Hi Dave,

I just updated the print sample with your great additions:
- dictionary that be used for custom values to be output (I transformed it to an ObservableDictionary that is useful in some scenarios).
- new events OnErrorPrinting, PageChanged and PrintProgress (I changed your event 'OnPrintInitializing' to 'PageChanged'. This allows to change the output by page and and to see the result in the preview window (not tied to the beginning of the print)).
Here is an example of output depending on the page (text changes).

Thank you very much for your suggestions.

The link to the code is not working. Can you please help? Also does the sample work with silverlight 3.2 API?

Re: Print map sample

DominiqueBroux — Mon, 20 Oct 2014 15:03:05 GMT

Looks like the links have been lost during forum migration :

A version of this sample is also available in the interactive SDK: Client Printing. This version is simplified (not multipage, no way to fix the scale) but the UI has been enhanced.

Thanks Dominique!

For some reason, when I chose print dialog and select a part of the map to print, it is not printing in the full page. This feature was working fine with earlier code when we were using Silverlight API 2.4. Would you know what could be the reason?

Re: Print map sample

DominiqueBroux — Thu, 23 Oct 2014 09:04:47 GMT

The sample is supposed to support Silverlight 3.2 since all live versions are using it.

I you can share a repro case, I'll look at it.
