java.lang.Objectorg.apache.fop.render.intermediate.AbstractIFPainter
org.apache.fop.render.ps.PSPainter
IFPainter implementation that produces PostScript.

INSTREAM_OBJECT_URI, state |
Constructor Summary | |
PSPainter(PSDocumentHandler documentHandler)
Default constructor. |
Method Summary | |
protected void |
beginTextObject()
Indicates the beginning of a text object. |
void |
clipRect(java.awt.Rectangle rect)
Restricts the current clipping region with the given rectangle. |
protected java.util.Map |
createDefaultImageProcessingHints(org.apache.xmlgraphics.image.loader.ImageSessionContext sessionContext)
Creates the default map of processing hints for the image loading framework. |
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. |
protected void |
drawImageUsingImageHandler(org.apache.xmlgraphics.image.loader.ImageInfo info,
java.awt.Rectangle rect)
Loads a preloaded image and draws it using a suitable image handler. |
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. |
protected void |
endTextObject()
Indicates the end of a text object. |
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. |
protected IFContext |
getContext()
Returns the intermediate format context object. |
protected void |
restoreGraphicsState()
Restores the last graphics state of the rendering engine. |
protected void |
saveGraphicsState()
Saves the graphics state of the rendering engine. |
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. |
