Detailed Description
PdfDifferenceEncoding is an encoding, which is based on either the fonts encoding or a predefined encoding and defines differences to this base encoding.

PoDoFo::PdfDifferenceEncoding::PdfDifferenceEncoding |
( |
PdfObject * |
pObject, |
|
|
bool |
bAutoDelete = true | |
|

Member Function Documentation
void PoDoFo::PdfDifferenceEncoding::AddToDictionary |
( |
PdfDictionary & |
rDictionary |
) |
const [virtual] |
Add this encoding object to a dictionary usually be adding an /Encoding key in font dictionaries.
- Parameters:
-
| rDictionary | add the encoding to this dictionary |
Convert a unicode PdfString to a string encoded with this encoding.
- Parameters:
-
| an | unicode PdfString. |
| pFont | the font for which this string is converted |
- Returns:
- an encoded PdfRefCountedBuffer. The PdfRefCountedBuffer is treated as a series of bytes and is allowed to have 0 bytes. The returned buffer must not be a unicode string.
PdfString PoDoFo::PdfDifferenceEncoding::ConvertToUnicode |
( |
const PdfString & |
rEncodedString, |
|
|
const PdfFont * |
pFont | |
|
) |
| | const [virtual] |
Convert a string that is encoded with this encoding to an unicode PdfString.
- Parameters:
-
| 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 |
- Returns:
- an unicode PdfString.
pdf_utf16be PoDoFo::PdfDifferenceEncoding::GetCharCode |
( |
int |
nIndex |
) |
const [virtual] |
Get the unicode character code for this encoding at the position nIndex. nIndex is a position between GetFirstChar() and GetLastChar()
- Parameters:
-
| nIndex | character code at position index |
- Returns:
- unicode character code
- See also:
- GetFirstChar
-
GetLastChar
Will throw an exception if nIndex is out of range.
Get read-only access to the object containing the actual differences.
- Returns:
- the container with the actual differences
const PdfName & PoDoFo::PdfDifferenceEncoding::GetID |
( |
|
) |
const [inline, protected, virtual] |
Get a unique ID for this encoding which can used for comparisons!
- Returns:
- a unique id for this encoding!
bool PoDoFo::PdfDifferenceEncoding::IsAutoDelete |
( |
|
) |
const [inline, virtual] |
- Returns:
- true if this encoding should be deleted automatically with the font.
bool PoDoFo::PdfDifferenceEncoding::IsSingleByteEncoding |
( |
|
) |
const [inline, virtual] |
- Returns:
- true if this is a single byte encoding with a maximum of 256 values.
