Filters that display or export pixel values ? like, software, features, display, anybody

andy

I'm looking for filters able to display or export pixel values from a video file ( RGB or YUV color space ). I've found ShowPixelValues and DumpPixelValues so far, but I'd like to know if others exist ?
siwalters_u...xelvalues.html
mcpoodle43/...xelValues.html

BTW, does anybody know an software which would provide the same features than these filters but in a more interactive way ?

Colourpicker does this.

Thanks a lot Kagura, I'll take a look at it.

What are you trying to do?

What would like to see added to ShowPixelValues ?

regards
Simon

I take liberty in adding some request. I use your plugin and thanks a lot for this useful one.
When using this in darker areas I find the numbers are also very dark and hardly readable. I played with some parameters like dim etc but did not succeed. Can they be made readable by switching off shading or coloring? If already built in sorry for the request but can you suggest how to switch off colors, shades?

@Si:
I'd like to be able to resize the analysis area in order to just get a few pixels values ( the results are pretty difficult to read with the default area size for me ... ). I'd also like to export the results as a text file. However, ShowPixelValues is a very helpful filter, thanks a lot for your work ;-)

@vcmohan
Please try this  

I've just modified YUY2 mode with an extra parameter ShowPixels (default=true).

If set to false, then it will not show the underlying pixel colours and all the writing will be white on black.

Please let me know if this is what you want.

I'll start coding the text file output (.csv OK ?).

How much bigger do you want the text to be (2x, 4x etc)  (I just use VirtualDub and set the window mag factor to 4x myself but I can see it might be useful to do it inside of my filter   )

Great !

4x should be ok I guess.
Many thanks for your help.

I get sometimes access violations with this plugin. I noticed them when I converted an odd sized png image to yuy format. After cropping I do not get those errors.

What size gives errors?
