Method Detail

isPlainTextFile

public static boolean isPlainTextFile(byte[] bytes,
                      String filename)
                               throws IOException

Detects if the data contains plain text.

Parameters:

bytes - data to analyze

filename - name of the file the data is contained in

Returns:

true if data contains plain text

Throws:

IOException - IO exception when trying to detect media type

getMediaType

public static String getMediaType(byte[] bytes,
                  String filename)
                           throws IOException

Detects the media type of the provided data.

Parameters:

bytes - original data

filename - name of the file the data was contained in

Returns:

media type (like 'text/plain' for plain text)

Throws:

IOException - IO exception when reading original data

convertTextToPdf

public static byte[] convertTextToPdf(byte[] original,
                      String font,
                      float fontSize)
                               throws com.lowagie.text.DocumentException,
                                      IOException

Converts the provided plain text data to PDF.

Parameters:

original - plain text data

font - font to use (like C:/Windows/Fonts/arial.ttf). This must be a true-type font! If null or empty, a default helvetica font will be used. Note that unicode characters will not work then.

fontSize - size of the font

Returns:

PDF document as array of bytes

Throws:

com.lowagie.text.DocumentException - Exception when creating the PDF document

IOException - IO exception when reading the original data

convertTextToPdf

public static byte[] convertTextToPdf(byte[] original,
                      String font,
                      float fontSize,
                      String defaultCharset)
                               throws com.lowagie.text.DocumentException,
                                      IOException

Converts the provided plain text data to PDF.

Parameters:

original - plain text data

font - font to use (like C:/Windows/Fonts/arial.ttf). This must be a true-type font! If null or empty, a default helvetica font will be used. Note that unicode characters will not work then.

fontSize - size of the font

defaultCharset - charset to use when auto-detection of charset failed

Returns:

PDF document as array of bytes

Throws:

com.lowagie.text.DocumentException - Exception when creating the PDF document

IOException - IO exception when reading the original data

getUnicodeString

public static String getUnicodeString(byte[] original)
                               throws IOException

Returns a unicode encoded string corresponding to the provided data. The encoding of the original data is auto-detected. If an unsupported encoding is detected, ISO-8859-1 is used as a fallback.

Parameters:

original - original data

Returns:

unicode string corresponding to original data

Throws:

IOException - IO exception when reading the original data

getUnicodeString

public static String getUnicodeString(byte[] original,
                      String defaultCharset)
                               throws IOException

Returns a unicode encoded string corresponding to the provided data. The encoding of the original data is auto-detected. If an unsupported encoding is detected, the provided fallback is used.

Parameters:

original - original data

defaultCharset - charset to use when auto-detection of charset failed

Returns:

unicode string corresponding to original data

Throws:

IOException - IO exception when reading the original data
