Hi,
I need to paint a JScrollBar. I noticed that if the JScrollBar is very small
you have only up and down buttons (no lift between), a fill3DRect to paint a
rectangle with a negative height (-1) is called.
You can see the trace I put in SVGShape.java and SVGRectangle.java:
printHack :
javax.swing.JScrollPane$ScrollBar[,483,25,15x28,layout=javax.swing.plaf.meta
l.MetalScrollBarUI,alignmentX=null,alignmentY=null,border=,flags=1185,maximu
mSize=,minimumSize=,preferredSize=,blockIncrement=10,orientation=VERTICAL,un
itIncrement=1]
Shape is : java.awt.geom.GeneralPath@58b7f Shape is :
java.awt.geom.GeneralPath@3dc777
Shape is : java.awt.Rectangle[x=0,y=0,width=15,height=28]
rect height = 28
Shape is : java.awt.geom.Line2D$Float@7282a1
Shape is : java.awt.geom.GeneralPath@5e4fa6
Shape is : java.awt.geom.Line2D$Float@3f4547
Shape is : java.awt.geom.Line2D$Float@5d669a
Shape is : java.awt.geom.Line2D$Float@7b41d6
Shape is : java.awt.geom.Line2D$Float@1f6177
Shape is : java.awt.geom.Line2D$Float@380316
Shape is : java.awt.geom.Line2D$Float@529976
Shape is : java.awt.geom.Line2D$Float@5941d7
Shape is : java.awt.Rectangle[x=0,y=0,width=0,height=-1]
rect height = -1
Shape is : java.awt.Rectangle[x=0,y=0,width=0,height=-1]
rect height = -1
I thought that it was an error, but in fact I get an SVG image identical to
my JScrollPane.
And if I modify the height of the rectangle (height becomes 0), I loose the
rendering of my ScrollPane in my SVG Image.
The problem is localized about JPEGTrancoder that I call next, to trancode
my SVG image into JPEG Image.
Here the exception I get with JPEG conversion:
org.apache.batik.bridge.BridgeException:
