Night Reader

Night Reader插件简介

Night Reader插件描述

This extension eases your eyes by inverting the brightness of every webpage you browse.
The majity of websites mainly use very light cols, but some already have a refreshing dark theme. F these the user can disable the domain, essentially setting it on a blacklist of the application.
Its goal is, in contrast to the approach of creating new webpage–specific templates, to be as general as possible. This is best achieved by applying the CSS filter invert to the document root, because it inverts the whole area in one swoop after it got rendered nmally instead of going through every element. This is even me efficient because CSS filters rely on the browser implementation, meaning all the good stuff like hardware acceleration  other system specific optimizations.
Images should still show nmally, but single elements cannot be excluded from the filter. This is no problem, since they can just get inverted on their own befe the whole document gets inverted, reverting the images to their iginal col.
To preserve the visual appearance of websites which may be iconic like the blue theme of Facebook, another filter is applied that rotates the hue back by 180 degrees. However, due to certain limitations of the RGB col model, very saturated cols get clipped in their value component that would have to exceed the maximum, resulting in occasional weird–looking images after they got reverted. Where an exact representation is needed, the hue–rotation can be disabled.

[TODO]

me ideas to be implemented in future releases are:
— serve options page to input custom CSS rules to optimize other websites
— friendly ui f options page (e.g. click [+] to add a rule, specify the  e.g. as regex, input CSS to be applied into text field)
— keyboard shtcuts f enabling/disabling on domain  me
— (maybe) make only–invert option domain specific
— (maybe) optionally stop inverting input text fields
— (do YOU have an idea? contact me!)

[KNOWN BUGS]

— (confirmed f Chrome) Prints get heavily pixelated when NightReader is enabled (even with "enabled globally" unchecked). There might be a possible fix in a future Version.
    Wkaround: disable Extension f printing
