> Is anything going to happen about fixing bug id 4151279

> My applet is written to JDK 1.0 and works well under browsers
> supporting
> JDK 1.0 and 1.1. There are problems with JDK 1.2.
>
> The applet uses small circles (4-10 pixel diameter) to act as
> markers on a map.
> The map itself is buffered through an offscreen image while
> the map legend is
> drawn directly to a window. Under JDK 1.0 and JDK 1.1 the
> offscreen image is
> an instance of sun.awt.motif.X11OffScreenImage while under
> JDK 1.2 it's a
> java.awt.image.BufferedImage.
>
> This results in the following problems:
>
> 1) Drawing the map is slower under 1.2 because more work is
> done in rendering
> the circles: there's all sorts of Bezier stuff happening
> in 1.2 whereas
> in 1.0 and 1.1 the circle rendering is passed off to the X server.
>
> 2) The circles in 1.2 look ugly, and non-circular.
>
> 3) The circles on the map (drawn to a
> java.awt.image.BufferedImage) have a
> different shape to those drawn directly to the legend
> window without any
> buffering. Drawing directly to a window is still using
> native X11 methods.
>
> The sun.awt.motif.X11OffScreenImage no longer exists in 1.2.
> Ideally I'd like
> to have it restored, preferably with the same API but using a
> different one if
> necessary, so that I can get the same behaviour under 1.2 as
> under previous
> versions.
