text height overflow at table with chinese_text_wrapping
Reported by Hiroshi Shirosaki | July 8th, 2009 @ 12:18 AM
Text height overflow at table cells when I use ':wrap => :character' option.
pdf.text_options.update(:wrap => :character)
The cell height calculated by height_of method is wrong.
naive_wrap method should be called with {:mode => :character}
option.
module Wrapping
def height_of(string, line_width, size=font_size)
string = naive_wrap(string, line_width, size)
string.lines.to_a.length * font.height_at(size) end
TODO: Replace with TeX optimal algorithm
def naive_wrap(string, line_width, font_size, options = {})
scan_pattern = options[:mode] == :character ? /./ : /\S+|\s+/
