I can't take all the credit for the find/announcement

http://forums.lavag.org/index.php?showtopic=208

Someone 'PJM Lv' announced it to infoLV w/ much greater detail before myself. Not being an active member at that time, I thought I stumbled onto something first.

I have 3 pages of notes on the different structures for the opCodes. Untill I can write a white paper, I may just have to scan them in and post here.

OOOOOOhhhhhh <Insert thunderclap here> something just hit me. Combining this knowledge within an actual LVOOP object to enhance the interaction and image manipulation possibilites.

Now if I only had the time..... oooh just got another idea for all you musicians. write a song to the tune of 'if I only had a brain' but about the cool LV things you would do if you'only had the time'

I guess that'll have to do for now. If you can combine some VIs with it, it would be even better.

Norm,

to bypass tst. I kindly ask you to scan the documents and upload them to the knowledge base of Lava. I am looking for a white paper on the picture control (birthday wish).
On the KB@lava we can cooperate, maybe Ben can kick in some of his knowledge?

"Ben can kick in some of his knowledge?"

I am not qualified to carry the ball on this one but I can kick it around a little.

The KB article on LAVA is a good idea. I'll watch for it and contribute what I can.

I'll see what  I can do to support Paul Ausitn's* invention.

BTW:

This Q reveals my age but did anyone else notice the similarties between HPGL and the Picture Control data format?

* Paul Austin (to the best of my knowlwdge) invented the Picture control and hold the patent on same.

[NJKirchner]

From what I heard that HPGL was the basis for the structure.... but that's just what a little worm told me before the little birdie came along and ate it.

Adam ROfer has put on LAVA some code that looks very promising

Norm, Ben just reminded of this thread. Did you find those notes you mentioned?

[NJKirchner]

I have them with me in austin (NI week) right now. Find me via the twitter link on the lava blog

There's a opcode that's not used in any VI:

22: Set Rectangular Mask

See this idea (that nobody seems to like) for a working VI...

There's another opcode that sets the offset for coordinates. But it's so low level, it can actually set the drawing outside the picture control.
