. : ChangeLog
Log message:
2006-06-12 Roman Kennke <address@hidden>
* gnu/java/awt/peer/gtk/CairoGraphics2D.java
(drawPixels): Include alpha in parameter list.
(cairoFill): Include alpha in parameter list.
(setComposite): Don't modify the color.
(draw(Shape))): Use fill when the current composite has an alpha
of != 1.0, so that the stroked shaped will be composited.
(fill(Shape)): Call cairoFill() with alpha.
(drawImage): Call drawPixels or drawSurface with alpha.
(drawGlyphVector): When composite alpha is != 1.0, render the
outline using fill() to enable compositing for text.
(drawRaster): Call drawPixels with alpha.
* gnu/java/awt/peer/gtk/CairoGraphics2D.java
(nativeDrawSurface): Include alpha in parameter list.
(drawSurface): Include alpha in parameter list. Pass it to
nativeDrawSurface().
* include/gnu_java_awt_peer_gtk_CairoGraphics2D.h
* include/gnu_java_awt_peer_gtk_CairoSurface.h:
Regenerated.
* native/jni/gtk-peer/gnu_java_awt_peer_gtk_CairoGraphics2D.c
(drawPixels): Handle possible alpha for compositing.
(cairoFill): Likewise.
* native/jni/gtk-peer/gnu_java_awt_peer_gtk_CairoSurface.c
(nativeDrawSurface): Handle possible alpha for compositing.
