Class: TCPDF_FILTERS - X-Ref
| getAvailableFilters() X-Ref |
| Get a list of available decoding filters. return: (array) Array of available filter decoders. |
| decodeFilter($filter, $data) X-Ref |
| Decode data using the specified filter type. param: $filter (string) Filter name. param: $data (string) Data to decode. return: Decoded data string. |
| decodeFilterStandard($data) X-Ref |
| Standard Default decoding filter (leaves data unchanged). param: $data (string) Data to decode. return: Decoded data string. |
| decodeFilterASCIIHexDecode($data) X-Ref |
| ASCIIHexDecode Decodes data encoded in an ASCII hexadecimal representation, reproducing the original binary data. param: $data (string) Data to decode. return: Decoded data string. |
| decodeFilterASCII85Decode($data) X-Ref |
| ASCII85Decode Decodes data encoded in an ASCII base-85 representation, reproducing the original binary data. param: $data (string) Data to decode. return: Decoded data string. |
| decodeFilterLZWDecode($data) X-Ref |
| LZWDecode Decompresses data encoded using the LZW (Lempel-Ziv-Welch) adaptive compression method, reproducing the original text or binary data. param: $data (string) Data to decode. return: Decoded data string. |
| decodeFilterFlateDecode($data) X-Ref |
| FlateDecode Decompresses data encoded using the zlib/deflate compression method, reproducing the original text or binary data. param: $data (string) Data to decode. return: Decoded data string. |
| decodeFilterRunLengthDecode($data) X-Ref |
| RunLengthDecode Decompresses data encoded using a byte-oriented run-length encoding algorithm. param: $data (string) Data to decode. |
| decodeFilterCCITTFaxDecode($data) X-Ref |
| CCITTFaxDecode (NOT IMPLEMETED - RETURN AN EXCEPTION) Decompresses data encoded using the CCITT facsimile standard, reproducing the original data (typically monochrome image data at 1 bit per pixel). param: $data (string) Data to decode. return: Decoded data string. |
| decodeFilterJBIG2Decode($data) X-Ref |
| JBIG2Decode (NOT IMPLEMETED - RETURN AN EXCEPTION) Decompresses data encoded using the JBIG2 standard, reproducing the original monochrome (1 bit per pixel) image data (or an approximation of that data). param: $data (string) Data to decode. return: Decoded data string. |
| decodeFilterDCTDecode($data) X-Ref |
| DCTDecode (NOT IMPLEMETED - RETURN AN EXCEPTION) Decompresses data encoded using a DCT (discrete cosine transform) technique based on the JPEG standard, reproducing image sample data that approximates the original data. param: $data (string) Data to decode. return: Decoded data string. |
| decodeFilterJPXDecode($data) X-Ref |
| JPXDecode (NOT IMPLEMETED - RETURN AN EXCEPTION) Decompresses data encoded using the wavelet-based JPEG2000 standard, reproducing the original image data. param: $data (string) Data to decode. return: Decoded data string. |
| decodeFilterCrypt($data) X-Ref |
| Crypt (NOT IMPLEMETED - RETURN AN EXCEPTION) Decrypts data encrypted by a security handler, reproducing the data as it was before encryption. param: $data (string) Data to decode. return: Decoded data string. |
| Error($msg) X-Ref |
| Throw an exception. param: $msg (string) The error message |
