Member Enumeration Documentation

writing_mode_enum

enum poppler::text_box::writing_mode_enum

Get a writing mode for the i-th glyph.

This method returns an enum of the writing mode for the i-th glyph in the text_box.

Note

Usually all glyphs in one text_box have the same writing mode. Thus the default value of the glyph index is 0.

char_bbox()

rectf text_box::char_bbox

(

size_t

i

)

const

Get a bbox for the i-th glyph.

This method returns a rectf of the bounding box for the i-th glyph in the text_box.

Note

The text_box object owns the rectf objects, the caller is not needed to free them.

Warning

For too large glyph index, rectf(0,0,0,0) is returned. The number of the glyphs and ustring codepoints might be different in some complex scripts.

get_font_name()

std::string text_box::get_font_name

(

int

i = 0

)

const

Get a font name for the i-th glyph.

This method returns a std::string object holding the font name for the i-th glyph.

Note

The randomization prefix of the embedded fonts are not removed. The font names including these prefixes are insuffucient to determine whether the two fonts are same or different.

The clients should not assume that the encoding of the font name is one of the ASCII, Latin1 or UTF-8. Some legacy PDF producers used in CJK market use GBK, Big5, Wansung or Shift-JIS.
