New filters: PixelInfo / PsetRGB - Page 2

hanfrunz · 24th March 2006, 11:47

we want that filter A (pget) reads the rgb values of a given pixel. These values should be stored in script-variables (r,g,b). Then other filters can use these values to do whatever you wish.

Probably you want

Code:

int n = 42;
env->SetGlobalVar("name", (AVSValue)n);

PushContext/PopContext would have to be involved but I am not quite sure why in this case. Are you env->Invoke'ing a 2nd chain? A single GetFrame chain should all be in the same context.

You may have to debug trace your way thru the code chain from the child->GetFrame() call in filterB down thru to the Set(Global)Var call in filterA::GetFrame.

There be dragons in that there code

How is the plugin coming?

HighInBC: Is there a way for avisynth to return the color of a specific pixel into an int?

Someone wants to use it for a whitebalance script. It proves my point that this is a needed function, as there's people with great ideas that can only script and not write a full plugin.

I still think, that it is not possible to for a filter to change a scriptvariable, but i will investigate if i have time. A new version with a preview-window will be uploaded the next days!

I don't understand the problem, but I asked IanB to give you a hand, has his suggestions not helped? If you can explain clearly I'm sure you can get help....
There's also the source code I left for you.

Have you found any time to work on this filter hanfrunz?

hanfrunz · 7th August 2006, 18:55

i worked a little bit on the pget() filter, but it's too buggy right now. I try to release a new version in a few days.

I can't download this filter.
Please check the adress,.

hanfrunz · 10th August 2006, 09:58

@windcool: please try again, works fine for me. Geocities is sometimes down...

yashar · 24th September 2006, 05:07

hanfrunz · 25th September 2006, 09:51

sometimes, i will release a new version soon.

Wilbert · 16th September 2007, 23:05

@jmac698,

Something like this:

Code:

LoadPlugin("F:\CompilingPlugins\PixelValue\Release\PixelValue.dll")

w = ColorBars(pixel_type="RGB32")
#w = ScriptClip(w, """Subtitle(String(RGB(200, 40, "B")))""")
#w = ScriptClip(w, """Subtitle(String(RGB(500, 40, "BGR")))""")
w = ScriptClip(w, """Subtitle(String(RGB(500, 40, "R")))""")
return w

See readme for further information and examples.

Anybody got the source for either PixelInfo or PixelValue, Geocities closed down.
Thought it might be handy to have a v2.6 colorspace compatible version.

could be done by simple scripts

yv12 - pointresize to yuy2
yv16 - converttoyuy2
yv24 - mergergb (y,u,v)
y8 - mergergb (last, last, last)

StainlessS · 26th February 2015, 17:48

I believe PixelInfo has a GUI.

feisty2 · 26th February 2015, 17:56

if you are interested, avspmod got a pixelinfo like function, available for all avisynth supported colorspaces, it very self is a GUI program, just put your mouse pointer at any pixel and it will show its info at the status bar

Here you go: pixelinfo0_3.zip

archive.org does not seem to have PixelValues archived. Maybe Wilbert still has it?

StainlessS · 26th February 2015, 19:47

Many thanks rd, you seem to have a copy of everything.

Reel.Deel · 26th February 2015, 22:02

Actually I got PixelInfo from Wilbert's plugin package here: http://forum.doom9.org/showthread.ph...hlight=package
