Class PtocaBuilder

Method Details

• getOutputStreamForControlSequence

  protected abstract OutputStream getOutputStreamForControlSequence(int length)

  Returns an OutputStream for the next control sequence. This gives a subclass a chance to do chunking of control sequences into multiple presentation text data objects.

  Parameters:

  length - the length of the following control sequence

  Returns:

  the output stream where the control sequence will be written to

• writeIntroducer

  public void writeIntroducer() throws IOException

  Writes the introducer for a chained control sequence.

  Throws:

  IOException - if an I/O error occurs

• setCodedFont

  public void setCodedFont(byte font) throws IOException

  The Set Coded Font Local control sequence activates a coded font and specifies the character attributes to be used.

  This is a modal control sequence.

  Parameters:

  font - The font local identifier.

  Throws:

  IOException - if an I/O error occurs

• absoluteMoveInline

  public void absoluteMoveInline(int coordinate) throws IOException

  Establishes the current presentation position on the baseline at a new I-axis coordinate, which is a specified number of measurement units from the B-axis. There is no change to the current B-axis coordinate.

  Parameters:

  coordinate - The coordinate for the inline move.

  Throws:

  IOException - if an I/O error occurs

• relativeMoveInline

  public void relativeMoveInline(int increment) throws IOException

  Moves the inline coordinate of the presentation position relative to the current inline position.

  Parameters:

  increment - the increment in 1/1440 inch units

  Throws:

  IOException - if an I/O error occurs

• absoluteMoveBaseline

  public void absoluteMoveBaseline(int coordinate) throws IOException

  Establishes the baseline and the current presentation position at a new B-axis coordinate, which is a specified number of measurement units from the I-axis. There is no change to the current I-axis coordinate.

  Parameters:

  coordinate - The coordinate for the baseline move.

  Throws:

  IOException - if an I/O error occurs

• addTransparentData

  public void addTransparentData(CharactersetEncoder.EncodedChars encodedChars) throws IOException

  The Transparent Data control sequence contains a sequence of code points that are presented without a scan for embedded control sequences. If the data is larger than fits in one chunk, additional chunks are automatically generated.

  Parameters:

  encodedChars - The encoded text data to add.

  Throws:

  IOException - if an I/O error occurs

• drawBaxisRule

  public void drawBaxisRule(int length, int width) throws IOException

  Draws a line of specified length and specified width in the B-direction from the current presentation position. The location of the current presentation position is unchanged.

  Parameters:

  length - The length of the rule.

  width - The width of the rule.

  Throws:

  IOException - if an I/O error occurs

• drawIaxisRule

  public void drawIaxisRule(int length, int width) throws IOException

  Draws a line of specified length and specified width in the I-direction from the current presentation position. The location of the current presentation position is unchanged.

  Parameters:

  length - The length of the rule.

  width - The width of the rule.

  Throws:

  IOException - if an I/O error occurs

• setTextOrientation

  public void setTextOrientation(int orientation) throws IOException

  The Set Text Orientation control sequence establishes the I-direction and B-direction for the subsequent text. This is a modal control sequence. Semantics: This control sequence specifies the I-axis and B-axis orientations with respect to the Xp-axis for the current Presentation Text object. The orientations are rotational values expressed in degrees and minutes.

  Parameters:

  orientation - The text orientation (0, 90, 180, 270).

  Throws:

  IOException - if an I/O error occurs

• setExtendedTextColor

  public void setExtendedTextColor(Color col) throws IOException

  The Set Extended Text Color control sequence specifies a color value and defines the color space and encoding for that value. The specified color value is applied to foreground areas of the text presentation space.

  This is a modal control sequence.

  Parameters:

  col - The color to be set.

  Throws:

  IOException - if an I/O error occurs

• setVariableSpaceCharacterIncrement

  public void setVariableSpaceCharacterIncrement(int incr) throws IOException

  Sets the variable space character increment.

  This is a modal control sequence.

  Parameters:

  incr - The increment to be set (positive integer, 1/1440 inch)

  Throws:

  IOException - if an I/O error occurs

• setInterCharacterAdjustment

  public void setInterCharacterAdjustment(int incr) throws IOException

  Sets the intercharacter adjustment (additional increment or decrement between graphic characters).

  This is a modal control sequence.

  Parameters:

  incr - The increment to be set (1/1440 inch)

  Throws:

  IOException - if an I/O error occurs

• endChainedControlSequence

  public void endChainedControlSequence() throws IOException

  A control sequence is a sequence of bytes that specifies a control function. A control sequence consists of a control sequence introducer and zero or more parameters. The control sequence can extend multiple presentation text data objects, but must eventually be terminated. This method terminates the control sequence (by using a NOP command).

  Throws:

  IOException - if an I/O error occurs
