SyntaxEditor : CreateFixedDocument FontFamily/FontSize doesn't render

Hi Mark,

Yes the code for rendering printer views doesn't resolve to the SyntaxEditor properties like editor views do.  The main reason is that the app might be in a dark theme, which assume uses white text.  And if you set one of the SyntaxEditor-level properties, they would override the highlighting style registry that you'd use for printer views, which could lead to text not showing up in the printout (due to it being a white).  Thoughts?

Yes, that makes sense.

Now, how do I set the font size and font family in a fixed document for printing?

For those that don't use Dark themes, this is needed.  Developers can write custom UI to handle those exceptions.

Thanks

Hi Mark,

If you change the line number margin with this sort of setting instead, it should affect both the editor and print views:

var lineNumbers = new DisplayItemClassificationTypeProvider().LineNumbers;
AmbientHighlightingStyleRegistry.Instance[lineNumbers].FontSize = 14;
AmbientHighlightingStyleRegistry.Instance[lineNumbers].FontFamilyName = "Verdana";

Ah, i didn't think to change the Ambient registry, but that makes sense since it's the default.  I will try today.  I noticed a similar issue with Copy/Paste clipboard methods coming out in the default font. 

Thanks for the quick response.

You could do similar things for PlainText too.

Here's the code I added. 

//Stomp on the FontSize and FontFamily for creating the fixed print document, then reset afterwards.
foreach (var style in editor.HighlightingStyleRegistry.HighlightingStyles)
{
style.FontSize = editor.FontSize;
style.FontFamilyName = editor.FontFamily.Source;
}

// Create the print document
var fixedDocument = editor.PrintSettings.CreateFixedDocument(editor);

// Reset
foreach (var style in editor.HighlightingStyleRegistry.HighlightingStyles)
{
style.FontSize = 0;
style.FontFamilyName = null;
}

Hi Mark,

If you look at the "SyntaxEditor / User Interface Features / Printing Features / Print Options" topic, there is a section in there about how you can make a special highlighting style registry just for printouts.  Then it wouldn't affect your other editors as how you are doing.
