Field Detail

TWIP_SCALE

public static double TWIP_SCALE

Each logical unit is mapped to one twentieth of a printer's point (1/1440 inch, also called a twip).

Constructor Detail

EMFRenderer

public EMFRenderer(EMFInputStream is)
            throws java.io.IOException

Constructs the renderer.

Parameters:

is - the input stream to read the EMF records from.

Throws:

java.io.IOException - if an error occurs reading the header.

Method Detail

getSize

public java.awt.Dimension getSize()

Gets the size of a canvas which would be required to render the EMF.

Returns:

the size.

paint

public void paint(java.awt.Graphics2D g2)

Paints the EMF onto the provided graphics context.

Parameters:

g2 - the graphics context to paint onto.

saveDC

public void saveDC()

Stores the current state. Used by SaveDC

retoreDC

public void retoreDC()

Retores a saved state. Used by RestoreDC

closeFigure

public void closeFigure()

closes and appends the current open figure to the path

fixViewportSize

public void fixViewportSize()

Logical units are mapped to arbitrary units with equally scaled axes; that is, one unit along the x-axis is equal to one unit along the y-axis. Use the SetWindowExtEx and SetViewportExtEx functions to specify the units and the orientation of the axes. Graphics device interface (GDI) makes adjustments as necessary to ensure the x and y units remain the same size (When the window extent is set, the viewport will be adjusted to keep the units isotropic).

drawOrAppendText

public void drawOrAppendText(java.lang.String text,

                             double y)

draws the text

Parameters:

text - Text

y - y-Position
