"For text strings encoded in Unicode, the first two bytes must be 254 followed by

255, representing the Unicode byte order marker, U+FEFF. (This sequence conflicts
|
|
with the PDFDocEncoding character sequence thorn ydieresis, which is unlikely
|
|
to be a meaningful beginning of a word or phrase.) The remainder of the
|
|
string consists of Unicode character codes, according to the UTF-16 encoding
|
|
specified in the Unicode standard, version 2.0. Commonly used Unicode values
|
|
are represented as 2 bytes per character, with the high-order byte appearing first
|
|
in the string."
|
|
|
|
In other words, if there are chars in a string with char code above 255, we
|
|
recode the string to UCS2 BE - string doubles in length and BOM is prepended.
|
|
|
|
HOWEVER!
|
|
Actual *content* (body) text (as opposed to strings used in document properties etc)
|
|
does NOT expect BOM. There, it is treated as a literal GID (Glyph ID)
|
|
|
|
Because of Adobe's focus on "you subset your fonts!" you are not supposed to have
|
|
a font that maps directly Unicode (UCS2 / UTF16BE) code to font GID, but you could
|
|
fudge it with "Identity-H" encoding and custom CIDtoGID map that mimics Unicode
|
|
code page. There, however, all characters in the stream are treated as GIDs,
|
|
including BOM, which is the reason we need to skip BOM in content text (i.e. that
|
|
that is tied to a font).
|
|
|
|
To signal this "special" PDFEscape / to8bitStream handling mode,
|
|
API.text() function sets (unless you overwrite it with manual values
|
|
given to API.text(.., flags) )

All data points in `lines` are relative to last line origin.

Plugin relies on having browser, DOM around. The HTML is pushed into dom and traversed.

Plugin relies on jQuery for CSS extraction.

Targeting HTML output from Markdown templating, which is a very simple

markup - div, span, em, strong, p. No br-based paragraph separation supported explicitly (but still may work.)
|
|
Images, tables are NOT supported.

Returns a widths of string in a given font, if the font size is set as 1 point.
|
|
|
|
In other words, this is "proportional" value. For 1 unit of font size, the length
|
|
of the string will be that much.
|
|
|
|
Multiply by font size to get actual width in *points*
|
|
Then divide by 72 to get inches or divide by (72/25.6) to get 'mm' etc.
