Logical Graphics Operations

[Thorsten Kiefer]

Hi,
I want to do some logical computations with my graphics cards.
And now I'm wondering if all 16 logical operations of the GPU
are available in Java. Are they ?
There is something like Graphics.setPaintMode() and
Graphics.setXORMode(...).
But these are not sufficient for me. I guess Oracel doesn't find
the 2D logical operations very useful and did not implement them.
Is that the case ?

No.

These libraries antedate Oracle's acquisition of Java, and no one knows if Sun
found these operations "very useful" or not. And don't

There is no direct relationship between 'java.awt.Graphics' and the graphics
card. The Java class depends on the OS's libraries to do its dirty work. If
those OS libraries use the graphics card's capabilities, then Java does on
their coattails.

As for the "16 logical operations", what do they have that
'java.awt.geom.AffineTransform' doesn't provide?

It would be very slow, but you can process images bitwise and do the
logical operation in Java.

What GPU? What operations? Are you speaking of raster operations?

I'm guessing these 16 functions:

I can see using java.util.BitSet.

How would java.awt.geom.AffineTransform work?

Have to something with all of these tomatoes. Zucchini anyone?
I love technology. Sliced bread. Microwave bacon.
Yum.

Which Microsoft must have found less than useful as they are not
implemented in GDI+.

This GPU binding looks interesting for numeric applications, but it
doesn't seem to include the "logical computations" mentioned by the OP.

On reflection, I wondered if this might refer to the composite
operations defined by Porter & Duff, but there's only 12 of them.

I think the reference to graphics card and GPU in the OP was an
(unintentional?) red herring.

The reference to 16 operations brought back faint memories of Windows
GDI API.

And may explain the somewhat caustic last sentences of the OP.
I think my oversensitivity is due to an excess of caffeine and sugar in
my diet.

Nice, thanks.
