decoding png binary to table
i want to create a plugin for image analysis.

i have to convert the binary png to table for that, but i don’t know how to do it.

the class i’m using:

[promptimportfile](https://developer.roblox.com/en-us/api-reference/function/studioservice/promptimportfile)
[file](https://developer.roblox.com/en-us/api-reference/class/file)
even if you get the binary contents, decoding it is quite the undertaking. you can find the format specs here if you want to try it, though:

[png specification: file structure](http://www.libpng.org/pub/png/spec/1.2/png-structure.html)

there are existing implementations in lua, such as [this one](https://github.com/delusionallogic/pnglua), but they don’t cove…
not [full disclosure] a linux person per se.

something similar to the following should work:

start simple with just enough code to test the concept.

see if it works and modify/correct as necessary.

then if it still does not work, then post your documented code accordingly along an explanation of what is or is not happening as you expect or desire. hi [@justusschl](/u/justusschl),

there is some import/export option for labels in debug mode, however i would not recommend to use it.

what you are trying to do should involve as little manual labor as possible (source of errors). i thought about it a bit and found something that could work. did you know the .ilp … this is my first time digging into the processing source code so i hope this helps. the problem you are facing is more of a java problem though than a processing one.

by extending pgraphics you would have to replace the renderer implementations to inherit from your subclass(tgraphics) and not pgrap… i would do it like this:

then reformate your data to match the instructions and sample data.

Perhaps it will help. I'm going to assume that you are getting your routine `copy`
  




 (adsbygoogle = window.adsbygoogle || []).push({});
 
  

from a module `File::Copy`
  




 (adsbygoogle = window.adsbygoogle || []).push({});
 
  

.


After a quick search in CPAN, I came across a module named [`File::Copy::Vigilant`
  




 (adsbygoogle = window.adsbygoogle || []).push({});](https://translate.googleusercontent.com/translate_c?depth=1&pto=aue&rurl=translate.google.com&sl=ru&sp=nmt4&tl=en&u=)that seems to suit your needs and successfully test reports from perl 5.6.



  




 (adsbygoogle = window.adsbygoogle || []).push({});
 
  

I also found [`File::Copy::Reliable`
  




 (adsbygoogle = window.adsbygoogle || []).push({});](https://translate.googleusercontent.com/translate_c?depth=1&pto=aue&rurl=translate.google.com&sl=ru&sp=nmt4&tl=en&u=), but it only has reports up to perl 5.8, although that doesn't prove anything. You might just be a bit of a traveling pioneer as far as module goes .... you need to run rstudio as "administrator" to be able to install into the system level package library.

note: please do not post screenshots, they are considered a bad practice here, post formatted code instead. here is how to do it.
