Hey,

you can find the Autotrace script here (only windows for today) :

http://animatic.no-ip.com/pub/dev/moho/js_autotrace.lua

Please place it in [moho]/menu/[yourScriptsDirectory]
and read the instruction at the top of the script
(you'll need to download autotrace binary and to edit a script variable accordingly)
Feedbacks welcome!

Regards

Greetings!

Your script sounds very interesting, I haven“t tried it or figured out if I can figure out how to set it up.

Could you post a short animation where you used it? Maybe that would help explain to all of us what your script does.
And why one would want to do it - what are the advantages of changing the image from raster to vector.

hey toonz,

i haven't such animation to show you right now,
but the idea is quiet simple and there are many applications :
>you prefer traditional drawing tools (pixel or even paper/scan) but use vectors for colors and 2d animation (thanks to moho!) This is how toonboom product work for instance.
>you want to animate a finished painting
>you want to give a cartoon look to video footage

This is endless but well be warned that image often needs to be preprocessed before vectorizing for a good results and my script doesn't solve this.

Regards!

TIP :
using autotrace to speed up moho interactivity !
(or any other raster to vector converter)

i found a very usefull usage of autotrace + js_autotrace.lua !

When i make image based characters in moho it slow things down..
So when i animate i display a vector version of the character and it plays almost real time in moho !
When the anim is ok i render the image version (png layers from photoshop layers >image ready export layers to png) and play it with audio using
my loop software + js_ram_player.lua

To make the vector version using autotrace+ js_autotrace.lua
i need to make a black and white version of my character in photoshop :
- image > adjustement > brightness and contrast -100 -100
- image > adjustement > invert
- image > color mode> indexed color > uniform (colors:3)
- save as png
- run js autotrace in moho and that's it !

Cool tool

I tried this today and it worked very well!

Would be cool to see something like a menu in Moho with some tracing options.. but for now this is something that is very useful and time saving.

Hey Snuddy!
thank you for the feedback (i feel less lonely now )..

Autotrace is very powerfull and accept a lot of option, what kind of options would you like?
Here is the huge list of autotrace options :

i didn't try yet the internal color reduction options (prefer to do it externally) but that would be a cool option...

best regards

Is this an internal script? We load in an image and run it in Moho?

yes you select a (pre filtered) image from the moho file browser and it is converted to eps and automatically imported in moho

hey!

for the script part it's just a matter of writing a little shell script for mac os (like under any unix os)
For the autotrace software i think there is a port to Tiger os X 10.4 through darwinPort.
Tell me if you can run this
http://autotrace.darwinports.com/
and i'll write the shell script for you

(i don't have a mac here!)

sincerly yours
