Re: [JAVA2D] Tiger and Opengl

[Chris Campbell]

Hi Brian,
Yes, I can see how that statement is a bit misleading.  We do indeed
treat a BasicStroke with width <= 1.0 (and no dashing) as a "thin
stroke", so in your case (width=0) drawLine() calls will be handled
directly by OpenGL.  A thin line will be rendered by OpenGL as 1 pixel
wide, which is consistent with the spec you mention.
Thanks for pointing this out.  I'll see what I can do to clarify the
article.

Hi Chris,
I noticed in your article (a very helpful one, BTW), under the "Stroke"
section, that drawLine is "sent directly to OpenGL only when there is
a thin
stroke (i.e. a default BasicStroke with width=1.0)".  I commonly use a
BasicStroke with width setting of 0, for which the documentation
indicates
will give me the thinnest stroke supported by the graphics device no
matter
the scale setting.
Is the condition for sending the drawLine to OpenGL specifically that
the
width setting is 1, or will 0 work as well?

Hi Iulian,
I had sent out a URL earlier in the week pointing to a
document I wrote
about the ins and outs of the OpenGL-based Java 2D pipeline.  Since
then, it's been published as a full java.net article (with some minor
clarifications made since the blog posting):

Thanks,
Chris

Hi Chris,

Hi Chris,
Cool article by the way.  It was actually the article
that promted
me to
dig back into my old java 2d projects and rerun them
with the opengl
pipeline
enabled.
Thanks, hope it is useful for you.
