#1826 — controllable java HTML re

  To: comp.lang.java.gui
Does anyone know any good "controllable" java HTML render?

By "controllable", what I want is:

1) I may not need to "physically" output the render result on screen,
render it in memory is all I need.
2) but I want to know each item's location after render!
For example, for this page, I want to know the relative (with respect
to the upper left (0,0)) location of the "My Groups", "Sign In", "Sign
Out", the location of the header of this post, etc.
In another words, I want to know:
Item/tag with value "My Groups" locates at pixel (600, 10) on the
screen after render.
Item/tag with value "New post" locates at pixel (700, 250) on the
screen after render. etc.

Any idea of it?

Thanks.

Why?*

* I know of pages where all these values would change
according not only to the user's screen size/resolution
and default font size, but also according to how much 
of the screen area (width/height) the user is willing to 
provide to the *rendering* *component* that displays it,
at that particular instant. (As well as stylesheets that the
user might use to overide the default look of pages, and 
a bazillion other things..)

What are these pages?  Are they all controlled by you?
Are they all known in advance (e.g. off one site)?

We are doing some other processings, which needs to know the locations
of each tag/item.

Yes, I agree the locations will be based on font size, design, screen
size, etc. We can assume these values are known in advance (or use
whatever default values), and the pages are known (say, saved on disk
already).

Any idea of how to get the location information?

Presumably you render the HTML to a bitmap, discard the HTML and further 
process the bitmap.
