While looking at the RichContentFeatures sample I realized the style attribute does not appear to be supported.
<html>
<head>
<title></title>
</head>
<body>
<p style="font-family:Courier New;font-size:8mm;color:rgb(0,0,0);text-decoration:underline line-through;">Test Text</p>
</body>
</html>
The above HTML does not render as expected. Is the style attribute supported? If not will it be supported it future versions?
I did not use font tag as it has been deprecated in HTML 4 and removed from HTML5.
Any additional information you can provide regarding HTML Everywhere feature (rich content) would be appreciated.
Thanks

hank you again. But now we have only a temporary fix for font name parser:
void CExtRichContentItem::stat_css_parm_handler_font_family( CExtRichContentItem * pRCI, CExtRichContentItem * pFoundHI, CExtRichStyleRule & styleChanging, const CExtRichStyleDescription & )
{
/*
POSITION pos = pFoundHI->m_listParms.GetHeadPosition();
for( ; pos != NULL; )
{
CExtRichContentItem * pStylesParmHI = pFoundHI->m_listParms.GetNext( pos );
CExtSafeString str = LPCTSTR(pStylesParmHI->m_strTagPV);
str.TrimLeft( __EXT_RICH_CONTENT_TRIM_CHARS_AND_QUOTES );
str.TrimRight( __EXT_RICH_CONTENT_TRIM_CHARS_AND_QUOTES );
if( pRCI->ParseFontFamily( styleChanging, LPCTSTR( str ) ) )
break;
}
*/
CExtSafeString strReCompose;
POSITION pos = pFoundHI->m_listParms.GetHeadPosition();
bool bFirst = true;
for( ; pos != NULL; )
{
CExtRichContentItem * pStylesParmHI = pFoundHI->m_listParms.GetNext( pos );
CExtSafeString str = LPCTSTR(pStylesParmHI->m_strTagPV);
str.TrimLeft( __EXT_RICH_CONTENT_TRIM_CHARS_AND_QUOTES );
str.TrimRight( __EXT_RICH_CONTENT_TRIM_CHARS_AND_QUOTES );
if( ! bFirst )
strReCompose += _T(" ");
else
bFirst = false;
strReCompose += str;
int nPos = strReCompose.Find( _T(",") );
if( nPos > 0 )
{
CExtSafeString strTry = strReCompose.Left( nPos );
strTry.TrimLeft( __EXT_RICH_CONTENT_TRIM_CHARS_AND_QUOTES );
strTry.TrimRight( __EXT_RICH_CONTENT_TRIM_CHARS_AND_QUOTES );
if( pRCI->ParseFontFamily( styleChanging, LPCTSTR( strTry ) ) )
return;
strReCompose = strReCompose.Right( strReCompose.GetLength() - nPos - 1 );
bFirst = true;
}
}
if( ! strReCompose.IsEmpty() )
{
strReCompose.TrimLeft( __EXT_RICH_CONTENT_TRIM_CHARS_AND_QUOTES );
strReCompose.TrimRight( __EXT_RICH_CONTENT_TRIM_CHARS_AND_QUOTES );
if( pRCI->ParseFontFamily( styleChanging, LPCTSTR( strReCompose ) ) )
return;
}
}
The final parser fix will require more than one method modification and it will be fixed a few hours later today. Please drop us an e-mail to the support mail box at this web site and we will provide you with the fix.

Again thanks for the quick reply. I may have stumbled upon another CExtRichContentLayout class bug. CExtRichContentItem::ParseCSSValue is parsing "Comic Sans MS" into "comic".
Pasting the below HTML into a document and loading in IE and pasting in the RichContentFeatures sample generate different results.
<html>
<head>
<title></title>
</head>
<body>
<p>
<span style="font-family:Comic Sans MS;font-size:8.46666666666667mm;color:rgb(0,0,0);font-weight:bold;font-style:italic;text-decoration:underline line-through;">Rich Text</span>
</p>
<p></p>
</body>
</html>

You found a bug in the CExtRichContentLayout class. The mm units are converted to target device units incorrectly. Thank you. Please update the source code for the following method:
LONG CExtRichContentLayout::ConvMm2Px( DOUBLE lgMm, bool bHorz ) const
{
DOUBLE lfRes = lgMm * ( bHorz ? DOUBLE(g_PaintManager.m_nLPX) : DOUBLE(g_PaintManager.m_nLPY) ) / 2.54 / 10.0;
DOUBLE lfResCeil = ::ceil( lfRes );
DOUBLE lfFraction = 1.0 - ( lfResCeil - lfRes );
if( lfFraction >= 0.5 )
lfRes = lfResCeil;
else
lfRes = ::floor( lfRes );
return LONG(lfRes);
}
Both updated methods are inside 2.92. You can drop us an e-mail to the support mail box and we will provide you with 2.92 download.

Thanks for the quick reply. The code provided allows multiple text-decoration’s to be applied. Will this be included in Prof-UIS 2.9.2?
On another CSS style attribute note, font-size:8mm appears to be converted to 3px which doesn’t match other HTML renders (I.E., Firefox, Etc.).
Pasting the below HTML into a document and loading in IE and pasting in the RichContentFeatures sample generate different results.
<html>
<head>
<title></title>
</head>
<body>
<p>
<span style="font-family:Gabriola Bold Italic;font-size:8mm;color:rgb(0,0,0);font-weight:bold;font-style:italic;text-decoration:underline line-through;">Rich Text Format</span>
<span style="font-family:Gabriola Bold Italic;font-size:3px;color:rgb(0,0,0);font-weight:bold;font-style:italic;text-decoration:underline line-through;">Rich Text Format</span>
<span style="font-family:Gabriola Bold Italic;font-size:30px;color:rgb(0,0,0);font-weight:bold;font-style:italic;text-decoration:underline line-through;">Rich Text Format</span>

Thank you for reporting this issue. We implemented a single value text-decoration CSS attribute. I.e. you can only specify text-decoration:underline; or text-decoration:line-through;. But it’s not difficult to extend text-decoration support for multiple values. Please update the source code for the following method:
void CExtRichContentItem::stat_css_parm_handler_text_decoration( CExtRichContentItem *, CExtRichContentItem * pFoundHI, CExtRichStyleRule & styleChanging, const CExtRichStyleDescription & )
{
int nCount = int(pFoundHI->m_listParms.GetCount());
if( nCount < 1 )
return;
POSITION pos = pFoundHI->m_listParms.GetHeadPosition();
for( ; pos != NULL; )
{
CExtRichContentItem * pStylesParmHI = pFoundHI->m_listParms.GetNext( pos );
CExtSafeString str = LPCTSTR(pStylesParmHI->m_strTagPV);
str.TrimLeft( __EXT_RICH_CONTENT_TRIM_CHARS );
str.TrimRight( __EXT_RICH_CONTENT_TRIM_CHARS );
if( str.IsEmpty() )
continue;
str.MakeLower();
if( str == _T("underline") )
styleChanging.m_nUnderline = 1;
if( str == _T("line-through") )
styleChanging.m_nStrikeOut = 1;
// if( str == _T("overline") )
// styleChanging.m_nOverline = 1;
// if( str == _T("blink") )
// styleChanging.m_nBlink = 1;
}
}
