Constructor Summary | |
Java2DPainter(java.awt.Graphics2D g2d,
IFContext context,
FontInfo fontInfo)
Main constructor. |
|
Java2DPainter(java.awt.Graphics2D g2d,
IFContext context,
FontInfo fontInfo,
IFState state)
Special constructor for embedded use (when another painter uses Java2DPainter to convert part of a document into a bitmap, for example). |
Method Summary | |
void |
clipRect(java.awt.Rectangle rect)
Restricts the current clipping region with the given rectangle. |
protected RenderingContext |
createRenderingContext()
Creates a new RenderingContext instance. |
void |
drawBorderRect(java.awt.Rectangle rect,
BorderProps before,
BorderProps after,
BorderProps start,
BorderProps end)
Draws a border rectangle. The border segments are specified through BorderProps
instances. |
void |
drawImage(org.w3c.dom.Document doc,
java.awt.Rectangle rect)
Draws an image (represented by a DOM document) inside a given rectangle. This is the equivalent to an fo:instream-foreign-object in XSL-FO. |
void |
drawImage(java.lang.String uri,
java.awt.Rectangle rect)
Draws an image identified by a URI inside a given rectangle. This is the equivalent to an fo:external-graphic in XSL-FO. |
void |
drawLine(java.awt.Point start,
java.awt.Point end,
int width,
java.awt.Color color,
RuleStyle style)
Draws a line. NOTE: Currently, only horizontal lines are implemented! |
void |
drawText(int x,
int y,
int letterSpacing,
int wordSpacing,
int[] dx,
java.lang.String text)
Draws text. The initial coordinates (x and y) point to the starting point at the normal baseline of the font. The parameters letterSpacing, wordSpacing and the array dx are optional and can be used to influence character positioning (for example, for kerning). |
void |
endGroup()
Ends the current group and restores the previous coordinate system. |
void |
endViewport()
Ends the current viewport and restores the previous coordinate system. |
void |
fillRect(java.awt.Rectangle rect,
java.awt.Paint fill)
Fills a rectangular area. |
IFContext |
getContext()
Returns the intermediate format context object. |
protected FontInfo |
getFontInfo()
Returns the associated FontInfo object. |
protected Java2DGraphicsState |
getState()
Returns the Java2D graphics state. |
protected void |
restoreGraphicsState()
Restores the last graphics state from the stack. |
protected void |
saveGraphicsState()
Saves the current graphics state on the stack. |
void |
startGroup(java.awt.geom.AffineTransform transform)
Starts a new group of graphical elements. Corresponds to SVG's g element. |
void |
startViewport(java.awt.geom.AffineTransform transform,
java.awt.Dimension size,
java.awt.Rectangle clipRect)
Starts a new viewport, establishing a new coordinate system. A viewport has a size and can optionally be clipped. Corresponds to SVG's svg element. |
