InputStream.skip()
-method that doesn't seem to work properly for big values of size
.
stream
- the InputStream
size
- the number of bytes to skip
IOException

byte
array according to the PDF conventions.
bytes
- the byte
array to escape
byte
array
public static void writeEscapedString(OutputStream outputStream, byte[] bytes)
byte
array according to the PDF conventions.
outputStream
- the OutputStream
an escaped byte
array write to.

IOException
public static byte[] inputStreamToArray(InputStream stream) throws IOException
stream
- the stream to read
IOException
- if there is a problem reading from the input stream
public static void copyBytes(IRandomAccessSource source, long start, long length, OutputStream output) throws IOException
RandomAccessSource
to OutputStream
.
source
- the RandomAccessSource
copy from.
start
- start position of source copy from.
length
- length copy to.
output
- the OutputStream
copy to.
IOException
- on error.
public static void readFully(InputStream input, byte[] b, int off, int len) throws IOException
len
bytes from an input stream.
b
- the buffer into which the data is read.
off
- an int specifying the offset into the data.
len
- an int specifying the number of bytes to read.
EOFException
- if this stream reaches the end before reading all the bytes.
IOException
- if an I/O error occurs.
