Java2DGraphicsState
public Java2DGraphicsState(java.awt.Graphics2D graphics, FontInfo fontInfo, java.awt.geom.AffineTransform at)
State for storing graphics state.- Parameters:
graphics
- the graphics associated with the BufferedImagefontInfo
- the FontInfo from the rendererat
- the initial AffineTransform containing the scale transformation
-
Java2DGraphicsState
public Java2DGraphicsState(Java2DGraphicsState org)
Copy constructor.- Parameters:
org
- the instance to copy
-
-
Method Detail
-
getGraph
public java.awt.Graphics2D getGraph()
- Returns:
- the currently valid state
-
dispose
public void dispose()
Frees resources allocated by the current Graphics2D instance.
-
updateColor
public boolean updateColor(java.awt.Color col)
Set the current background color. Check if the background color will change and then set the new color.- Parameters:
col
- the new color as a java.awt.Color- Returns:
- true if the background color has changed
-
getColor
public java.awt.Color getColor()
- Returns:
- the current java.awt.Color
-
updateFont
public boolean updateFont(java.lang.String name, int size)
Set the current font name. Check if the font name will change and then set the new name.- Parameters:
name
- the new font namesize
- the font size- Returns:
- true if the new Font changes the current Font
-
getFont
public java.awt.Font getFont()
- Returns:
- the current java.awt.Font
-
updateStroke
public boolean updateStroke(float width, int style)
Sets the current Stroke. The line width should be set with updateLineWidth() before calling this method- Parameters:
width
- the line widthstyle
- the constant for the style of the line as an int- Returns:
- true if the new Stroke changes the current Stroke
-
getStroke
public java.awt.BasicStroke getStroke()
- Returns:
- the currently active Stroke
-
updatePaint
public boolean updatePaint(java.awt.Paint p)
Set the current paint. This checks if the paint will change and then sets the current paint.- Parameters:
p
- the new paint- Returns:
- true if the new paint changes the current paint
-
updateClip
public boolean updateClip(java.awt.Shape cl)
Set the current clip. This either sets a new clip or sets the clip to the intersect of the old clip and the new clip.- Parameters:
cl
- the new clip in the current state- Returns:
- true if the clip shape needed to be updated
-
transform
public void transform(java.awt.geom.AffineTransform tf)
Composes an AffineTransform object with the Transform in this Graphics2D according to the rule last-specified-first-applied.- Parameters:
tf
- the transform to concatenate to the current level transform- See Also:
Graphics2D.transform(AffineTransform)
-
getTransform
public java.awt.geom.AffineTransform getTransform()
Get the current transform. This gets the combination of all transforms in the current state.- Returns:
- the calculate combined transform for the current state
-
