color picker issue - tvp pixel interpolation affects on color picker

[ini]

Hello, My friend is working in japanese animation industry.
and when they put the color on the usual image, they use color without transparency. (not antialiased image)

When Image has many pixels(I think according to magnification rate, like default 150%?), tvpaint put the interpolation on the image.
I think It's same as other program, maybe they have their own interplation on what we see from the screen too.

When the image have only two pixel which has (255,255,255) and (0,0,0).
Incase of that the image is minimized, so the interplation is active,
Tvpaint color picker is picking interplated pixel's color, like (64,64,64) which is not exist on original pixel.
on the other hand, other program which is usually they are using is pick only exist pixel color.

I made him a script which is turning the intelpolation off when the picking the color.
but, I think general users can't use that way if they are not know the scripting on tvp.

I'm wondering that it's intentional thing.

for example,
in this img, there is only black(0,0,0) and grey(121,121,121)

no Anti-Aliasing, but with tvp interpolation, color picker is picking non exist color like (253,253,253) (52,52,52)

This matter was requested from our studio in the closed section three years ago.

(82)Using the color picker when the zoom window is zoomed out may pick up RGB values ​​mixed with the neighbor value
→Not solved

This is one of the reasons why Japanese painters and animators don't use TVPaint.

I attached the link of this video at that time.
It is an explanation of picking up colors from a small screen.

I see, I didn' know that.

Here is the script that I shared to my friend,
check it out If you want, Takagi-san

ちなみにPixelInterpolation後の数字は画面の倍率によって適用されます。
"tv_display PixelInterpolation 0.5"は画面の倍率50%からPixelInterpolationされます。
"tv_display PixelInterpolation 0"はPixelInterpolationなしになるので、
TPデータだとモニター解像度限界以上の大きい場合、或いはそれ以上縮小するとピクセルが消えます。

Hello ini,

I've run some tests on my side and I did manage to reproduce it:

interpolation.png (58.67 KiB) Viewed 2789 times

My project's dimensions are 2560x1440, and I was at 78,5% zoom ratio, but I was able to have the issue with 103% zoom ratio.

It won't be fixed for next release (hopefully next week) but we'll see what we can do for the next one.

Nice to here that!
