tv_customMode

[SebGodard]

Bonjour!

Est-ce que quelqu'un aurait plus d'information sur un script George inclus dans les brosses de remplacement de couleur (Tint [color], Paint over lines to turn them [color]).

Je vois qu'elles font appel à la commande tv_custommode, décrite sur ce lien dans le tvpaint wiki.
https://wiki.tvpaint.com/index.php?title=Tv_CustomMode

J'aimerai savoir à quoi correspondent les 4 groupes d'argument r, g, b, a, k, s'il vous plait.

Mon but est de créer une brosse qui puisse replacer des traits de n'importe quelle couleur (y compris noir) par la couleur A. Peut etre qu'on peut y arriver simplement autrement? Le mode tint et colorize ne marchent pas avec le noir, vu que c'est basé sur la luminosité, si j'ai bien compris.

Once again in english:

Could somebody describe to me how to craft a brush that colorizes previous strokes to colour A?

I tried with modes, but to no avail. I looked at the tint brushes "Paint over lines to turn them [color]", but they output only preset colors.

These brushes run with the tv_custommode command, which I can't really find documentation about execept this: https://wiki.tvpaint.com/index.php?title=Tv_CustomMode Maybe they could be tweaked to output color A?

Any ideas?

HI, quick update,

For the record , here is a more complete doc on tv_custommode: https://www.tvpaint.com/doc/tvpaint-ani ... custommode

I understand now that these arguments are a pixel matrix: https://wiki.tvpaint.com/index.php?title=Tv_PixelMatrix

I have fiddled with it quite a while. Here is my script:

Code: Select all

Param None
getcolor()

Function getColor()
tv_GetAPen
Parse result r g b alpha

tv_custommode 0 0 0 0 r  0 0 0 0 g  0 0 0 0 b  0 0 0 0 alpha  

End

...
the result not far from true, but acts a bit weird. And it still cannot replace true black (255). All other shades work fine.

ok I think I got there in the end.
Still coould be improved I think but it's my first contact with George, so...

If anybody is interested, here is the tool:

Probably there was already a tool to achieve this, but I couldn't find it.

Any comments are welcome.

I think what you want to do is control with Preserve transparency On / Off.

To change the color by stroke using tv_CustomMode,
you need "Type Script's Command" instead of "Embeded George Script".
"Type Script's Command" can only be entered on one line, can not specify the color with a variable.

Yeah, there's this script originally by Svengali, I tweaked it a bit to work with newer TVP versions it does what you would expect from a replace with A color.

Thank you for your answers,

Hironori Takagi:
Yes, preserve transparency toggle is a way to do this.
Actually the script works OK with EmbeddedGeorgeScript, and I believe lets you chose the A color. But your preserve transparency solution seems better to me, thank you.
Well at least I learned about george

cgmodeler:
Thanks for the tool, it works fine. Best of all, it can be applied to heads on a single click... I actually did try with the previous version, without success

Thank you all!
