API 2.0 and Printing to scale

[BrianBorg]

I am using the API 2.0 and I want to print maps using pre-defined scales (e.g. 1:1000, 1:2500, etc.) on different papersizes up to A0. I also want to use print templates. I think that I need to use some sort of services (e.g. ArcObjects) to generate such maps. Are there any examples around? or can someone point me to the right direction please?

I have read that there is something called layout SOE. What is it? How to use it?

Strange.

The code to enable the print command is quite simple:

 
private bool CanPrint(object param)
{
return IsPrinting == false && Map != null;
}

So very likely the Map property is null, but I can't figure out why.

If you want, send me your code by mail dbroux@esri.com, I'll take a look.

Dominique: My printing control has started working. The print preview isn't working, but I may have an idea of what's wrong. I'll keep working on it and let you know if I need additional help. Thanks again!

I just added a WPF version of the map printing sample.

With this version, an intermediary XPS document is created and can be previewed before printing.
Test it live.

Dominique,

Thanks again for your excellent work on the printing sample. I have been using the direct printing sample a lot. After your most recent changes, it appears that the direct printing sample is broken. I have a feeling it's related to the code you've added to free the cloned map layers, but I don't know for sure.

Dan,

You are right, there is a bug. To fix it, line 424 of MapPrinter.cs, move the initialization of _oldMap inside the test Map!=null:

if (Map != null)
{
  _oldMap = Map;
  Map = null;
}
ResetDefineExtent();

I will update the sample ASAP (I guess I should even revisit this badly designed part of the sample)

Thanks Dominique. That works on my end. I thought I would share a couple of snippets I added/modded to MapPrinter.theme.xaml:

[HTML]<ControlTemplate TargetType="local:MapPrinter">
...
<!-- Body-->
<Grid Grid.Row="1">
<!-- Map-->
<esri:Map x:Name="PrintMap" ...
</esri:Map>

<!-- Scale Bar -->
<esri:ScaleBar Map="{Binding ElementName=PrintMap}" HorizontalAlignment="Left" VerticalAlignment="Bottom"
        Margin="20" TextColor="Black" RenderTransformOrigin="0,1">
    <esri:ScaleBar.RenderTransform>
        <RotateTransform Angle="{Binding Rotation, ElementName=PrintMap}" />
    </esri:ScaleBar.RenderTransform>
</esri:ScaleBar>

<!-- North Arrow -->
<Grid Width="50" Height="50" Margin="20"
                HorizontalAlignment="Right" VerticalAlignment="Top"
                RenderTransformOrigin=".5,.5" Opacity="0.7">
    <Grid.RenderTransform>
        <RotateTransform Angle="{Binding Rotation, ElementName=PrintMap}" />
    </Grid.RenderTransform>
    <Path Data="M0.5,0 L0,1 L0.5,0.8 L1,1 z" Fill="White" Stretch="Fill" Stroke="Black" UseLayoutRounding="False" />
    <TextBlock Text="N" HorizontalAlignment="Center" VerticalAlignment="Center" FontWeight="Bold" FontSize="22" RenderTransformOrigin="0.5,0.5" >
        <TextBlock.RenderTransform>
            <CompositeTransform TranslateY="4"/>
        </TextBlock.RenderTransform>
    </TextBlock>
</Grid>
...
</Grid>
...
</ControlTemplate>[/HTML]

Thanks Dan,

A North Arrow is a good idea  (furthermore well oriented:))
I will integrate your enhancement in the next version of the sample.
