PdfEncoding (int nFirstChar, int nLastChar) | |
virtual const PdfName & | GetID () const =0 |
A PdfEncoding is in PdfFont to transform a text string into a representation so that it can be displayed in a PDF file.
PdfEncoding can also be used to convert strings from a PDF file back into a PdfString.
PoDoFo::PdfEncoding::PdfEncoding | ( | int | nFirstChar, |
int | nLastChar | ||
) | [protected] |
Create a new PdfEncoding.
nFirstChar | the first supported character code (either a byte value in the current encoding or a unicode value) |
nLastChar | the last supported character code, must be larger than nFirstChar
|
virtual void PoDoFo::PdfEncoding::AddToDictionary | ( | PdfDictionary & | rDictionary | ) | const [pure virtual] |
Add this encoding object to a dictionary usually be adding an /Encoding key in font dictionaries.
rDictionary | add the encoding to this dictionary |
Implemented in PoDoFo::PdfSimpleEncoding, PoDoFo::PdfDifferenceEncoding, and PoDoFo::PdfIdentityEncoding.
PdfEncoding::const_iterator PoDoFo::PdfEncoding::begin | ( | ) | const [inline] |
Iterate over all unicode character points in this encoding, beginning with the first.
virtual PdfRefCountedBuffer PoDoFo::PdfEncoding::ConvertToEncoding | ( | const PdfString & | rString, |
const PdfFont * | pFont | ||
) | const [pure virtual] |
Convert a unicode PdfString to a string encoded with this encoding.
rString | an unicode PdfString. |
pFont | the font for which this string is converted |
Implemented in PoDoFo::PdfSimpleEncoding, PoDoFo::PdfDifferenceEncoding, and PoDoFo::PdfIdentityEncoding.
virtual PdfString PoDoFo::PdfEncoding::ConvertToUnicode | ( | const PdfString & | rEncodedString, |
const PdfFont * | pFont | ||
) | const [pure virtual] |
Convert a string that is encoded with this encoding to an unicode PdfString.
rEncodedString | a string encoded by this encoding. Usually this string was read from a content stream. |
pFont | the font for which this string is converted |
Implemented in PoDoFo::PdfSimpleEncoding, PoDoFo::PdfDifferenceEncoding, and PoDoFo::PdfIdentityEncoding.
PdfEncoding::const_iterator PoDoFo::PdfEncoding::end | ( | ) | const [inline] |
Iterate over all unicode character points in this encoding, beginning with the first.
virtual pdf_utf16be PoDoFo::PdfEncoding::GetCharCode | ( | int | nIndex | ) | const [pure virtual] |
Get the unicode character code for this encoding at the position nIndex. nIndex is a position between GetFirstChar() and GetLastChar()
nIndex | character code at position index |
Will throw an exception if nIndex is out of range.
Implemented in PoDoFo::PdfSimpleEncoding, PoDoFo::PdfDifferenceEncoding, and PoDoFo::PdfIdentityEncoding.
int PoDoFo::PdfEncoding::GetFirstChar | ( | ) | const [inline] |
virtual const PdfName& PoDoFo::PdfEncoding::GetID | ( | ) | const [protected, pure virtual] |
Get a unique ID for this encoding which can used for comparisons!
Implemented in PoDoFo::PdfSimpleEncoding, PoDoFo::PdfDifferenceEncoding, and PoDoFo::PdfIdentityEncoding.
int PoDoFo::PdfEncoding::GetLastChar | ( | ) | const [inline] |
virtual bool PoDoFo::PdfEncoding::IsAutoDelete | ( | ) | const [pure virtual] |

virtual bool PoDoFo::PdfEncoding::IsSingleByteEncoding | ( | ) | const [pure virtual] |
Implemented in PoDoFo::PdfSimpleEncoding, PoDoFo::PdfDifferenceEncoding, and PoDoFo::PdfIdentityEncoding.
bool PoDoFo::PdfEncoding::operator< | ( | const PdfEncoding & | rhs | ) | const [inline] |
Comparison operator.
rhs | the PdfEncoding to which this encoding should be compared |
bool PoDoFo::PdfEncoding::operator== | ( | const PdfEncoding & | rhs | ) | const [inline] |
Comparison operator.
rhs | the PdfEncoding to which this encoding should be compared |
