Thanks for the valuable info as always. I will give it a try.

I haven't proven it in the debugger, but it appears that underlines are handled in TLF in FlowLeafElement.as. There is a method in there called getComputedFontMetrics. You could try monkey patching that. If you don't like monkey-patching and are using embedded fonts, there might be a way to intercept in the swfContext API. -Alex On 6/28/13 8:29 AM, "Miguel Ferreira" <[email protected]> wrote: >Hi Alex, >Is truly rich, is a web to print solution Enterprise application that i >join on the last 5 months. >Why i wish a solution like this:To make what the user see on the web and >get it on the PDF.The PDF creator uses SVG embebed fonts and when the >user set underline we have different results. >I could draw the lines with the example of justin from the post: >-------------------------------------------------------------------------- >------------From inside createTextLinesFromTextBlock method in >FTETextField. // FTE doesn't render underlines, > // but it can tell us where to draw them. >// You can't draw in a TextLine but it can have children, > // so we create a child Shape to draw them in. > var fontMetrics:FontMetrics; if >(fontContext) fontMetrics = >fontContext.callInContext(elementFormat.getFontMetrics, elementFormat, >[]); else fontMetrics = >elementFormat.getFontMetrics(); >var shape:Shape = new Shape(); var g:Graphics = >shape.graphics; >g.lineStyle(fontMetrics.underlineThickness, >elementFormat.color, elementFormat.alpha); g.moveTo(0, >fontMetrics.underlineOffset); >g.lineTo(textLine.textWidth, fontMetrics.underlineOffset); >-------------------------------------------------------------------------- >------------ >but i don't know on the RTE where i can override the TextBlock that >creates the textlines/underline. >In on component RTE all the text is underline i dont have parcial text >underline. > >I have my extended RTE with just textValidation (if font have glyph) and >font face validation. > >What looks easy to underline gap and thickness is not so easy i tough >that i could add this to TLF configuration but not.What i read is that >FontMetrics have the metrics of the embebed fonts as i said i tried to >fake this class but also with no success..(maybe the wrong >solution/perspective). > > > > >> From: [email protected] >> To: [email protected] >> Date: Fri, 28 Jun 2013 08:14:11 -0700 >> Subject: Re: Text flow underline >> >> Hi Miguel, >> >> I think RET uses TLF to draw the underlines which relies on FontMetrics. >> Is this text truly "rich" (different font families, sizes and styles) or >> single font? >> >> -Alex >> >> On 6/28/13 7:57 AM, "Miguel Ferreira" <[email protected]> >> wrote: >> >> >Hi Justin and Alex, >> >I am using RichEditableText.
