Overrides sun.print.PathGraphics.drawString.

public void
fill(Shape s, Color color)

Overrides sun.print.PathGraphics.fill.

public void
redrawRegion(Rectangle2D region, double scaleX, double scaleY, Shape savedClip, AffineTransform savedTransform)

Implements abstract sun.print.PathGraphics.redrawRegion.

Redraw a rectangular area using a proxy graphics To do this we need to know the rectangular area to redraw and the transform & clip in effect at the time of the original drawImage

protected boolean drawImageToPlatform(Image image, AffineTransform xform, Color bgcolor, int srcX, int srcY, int srcWidth, int srcHeight, boolean handlingTransparency)

Implements abstract sun.print.PathGraphics.drawImageToPlatform.

The various drawImage() methods for WPathGraphics are all decomposed into an invocation of drawImageToPlatform. The portion of the passed in image defined by srcX, srcY, srcWidth, and srcHeight is transformed by the supplied AffineTransform and drawn using PS to the printer context.

Parameters
image:Image

The image to be drawn. This method does nothing if img is null.

xform:AffineTransform

Used to transform the image before drawing. This can be null.

bgcolor:Color

This color is drawn where the image has transparent pixels. If this parameter is null then the pixels already in the destination should show through.

srcX:int

With srcY this defines the upper-left corner of the portion of the image to be drawn.

srcY:int

With srcX this defines the upper-left corner of the portion of the image to be drawn.

srcWidth:int

The width of the portion of the image to be drawn.

srcHeight:int

The height of the portion of the image to be drawn.

handlingTransparency:boolean

if being recursively called to print opaque region of transparent image

drawStringback to summary
public void drawString(String str, int x, int y)

Overrides sun.print.PathGraphics.drawString.

Draws the text given by the specified string, using this graphics context's current font and color. The baseline of the first character is at position (x, y) in this graphics context's coordinate system.

Parameters
str:String

the string to be drawn.

x:int

the x coordinate.

y:int

the y coordinate.

drawStringback to summary
public void drawString(String str, float x, float y)

Overrides sun.print.PathGraphics.drawString.

Renders the text specified by the specified String, using the current Font and Paint attributes in the Graphics2D context. The baseline of the first character is at position (x, y) in the User Space. The rendering attributes applied include the Clip, Transform, Paint, Font and Composite attributes. For characters in script systems such as Hebrew and Arabic, the glyphs can be rendered from right to left, in which case the coordinate supplied is the location of the leftmost character on the baseline.

Parameters
str:String

the String to be rendered
