How to remove white color...

Post by arche75 »

Greetings, everybody.

I have a question.
I used Luma Keyer to remove white color.
Please refer to the following picture.-the original image and the image used luma keyer
But, It is not what I wanted. The border is not clear and messy.
I know the Power Retouche Pro plugin for photoshop. This plugin can remove anti-alias.
I'd like the clear border. Because I work many images, I want to remove white color(anti-alias) at a time.
Please tell me, How to simply remove...

Try "Scan Cleaner" under "Color" in FX stack.

Hi Arche,
something must be wrong in your workflow, you shouldn't get this "white" antialias border
when working in the right way ...
can you tell us more about your process exactly ?
do you work in tvpa from scanned drawings ?
do you paint (color-fill) on a separate layer, other than the lines's one ?

anyway, during all your WIP, I would strongly recommend you to keep outlines and colors on different layers.

Hi~ ZigOtto

I understand you, as I have used a photoshop

TVPaint is a good program to create a 2D animation.
But, It's a pity there are no drawing function of correction like Adobe Flash.
My drawing line is zigzag. I want for line compensation function.
So I am using a Demo Verson Software(not Flash) , This software is a good for drawing and painting in 2D cell animation. (like Animo)
But It can't export due to demo verson. I capture a most big screen using caputer utility.
Alpha isn't in captured image. So I want to remove a white color (anti-alias next to border line)

OK I see, so, in your case, you can follow these steps :
- draw in your "vector-drawing" demo software (black lines on white BG),
- capture all your frames (.jpg or .png sequence) and import the sequence in tvpa,
- select all frames and Apply the Scan-Cleaner FX,
- hit the button, [Cl] button from the Instance Panel (= Clone Layer), and rename this new created layer "Color",
- fill with the apropriated colors by using the floodfill tool
(Source= Front, Fill = Density, Expend = 1, Smooth = 2, Range = 100)
Smooth, Expend, Gap-Closer and Range values could be tweaked differently depending on your drawing's lines (open or not, thickness, opacity, ...)
once finished the coloring process, playback the animation (at low frame-rate) to check everything is OK,
paint the missing pixels here and there (confined in sharp angle area f.i.), then you can merge the 2 layers,
(or better, select them, duplicate the selected layers, merge selected layers, and hide the 2 originals,
so you will keep a back-up of your pre-merge work.

Thank you...a detailed explanation.
But Idon't what I wanted. I'm so sorry.
I paint in demo software. Because The software can paint too easily.

for example,
* Automatic Color Trace
* Paint overflow Detection and close fill function - This function is in TVPaint. but this is much better than the TVPaint.
* Paint with light table color function - like auto pick color of the TVPaint
and so on...

so I take advantage of this software.

anyway, Thank you again for your interest in me.

OK, in that case, Importing already colored image on white BG, still remains a "2 steps FX" solution :
duplicate your AnimLayer (= sequence of your drawings),
- on the bottom one, apply a ScanCleaner FX,
- on the upper one, apply a CrossKeyer + AlphaControl FXs
then you can merge the 2 layers in one.

ps: save your FX bin for a later re-use, if needed .
:wink:
