Constructor Details

WMFPainter

public WMFPainter(WMFRecordStore currentStore,
 float scale)

Basic constructor.

Parameters:

currentStore - where the WMF records are stored

scale - the scale of the image

WMFPainter

public WMFPainter(WMFRecordStore currentStore,
 int xOffset,
 int yOffset,
 float scale)

Basic constructor.

Parameters:

currentStore - where the WMF records are stored

xOffset - x value for offset

yOffset - y value for offset

scale - the scale of the image

Method Details

paint

public void paint(Graphics g)

Renders the WMF image(s).

getPaint

private Paint getPaint(byte[] bit)

drawString

private void drawString(int flag,
 Graphics2D g2d,
 AttributedCharacterIterator ati,
 float x,
 float y,
 TextLayout layout,
 WMFFont wmfFont,
 int align)

Draw an AttributedCharacterIterator taking into account the following characteristics. :

• the orientation (escapement) of the WMF Font
• the aligment of the text

The other characteristics of the text, deriving from the WMF Font, must have been collected before to constitute the AttributedCharacterIterator.

fillTextBackground

private void fillTextBackground(int align,
 int flag,
 Graphics2D g2d,
 float x,
 float y,
 float width,
 TextLayout layout)

drawPolyPolygon

private void drawPolyPolygon(Graphics2D g2d,
 List pols)

Just to be consistent with PolyPolygon filling.

fillPolyPolygon

private void fillPolyPolygon(Graphics2D g2d,
 List pols)

Need to do this for POLYPOLYGON, because only GeneralPaths can handle complex WMF shapes.

setStroke

private void setStroke(Graphics2D g2d,
 int penStyle,
 float penWidth,
 float scale)

setPenColor

private void setPenColor(WMFRecordStore currentStore,
 Graphics2D g2d,
 int penObject)

getHorizontalAlignement

private int getHorizontalAlignement(int align)

setBrushPaint

private void setBrushPaint(WMFRecordStore currentStore,
 Graphics2D g2d,
 int brushObject)

getStoredPaint

private Paint getStoredPaint(WMFRecordStore currentStore,
 int object)

paint

private void paint(int brushObject,
 int penObject,
 Shape shape,
 Graphics2D g2d)

Draw or / and fill the Shape, depending on the pen or brush Objects selected.

paintWithPen

private void paintWithPen(int penObject,
 Shape shape,
 Graphics2D g2d)

Draw the Shape, depending on the pen or brush Objects selected.

getVerticalAlignmentValue

private float getVerticalAlignmentValue(TextLayout layout,
 int vertAlign)

getRecordStore

public WMFRecordStore getRecordStore()

Returns the WMFRecordStore this WMFPainter renders
