Differences between Canvas and Java

PixelZoomer uses different methods for rendering screenshots of an opened web page. The desired option can be activated in the settings. You can choose between "Java" and "Canvas". The Java method requires the activated runtime environment and needs a bit more time than the Canvas technique. The advantage of Java lies in the accurate rendering of pixels and colors because with the use of the Canvas method there may occur semi-transparent pixels (subpixels) which aren't present in the regular browser view. Below you can find an example for a better understanding.

The differences depend on your operating system an may appear sporadical. As the intention of PixelZoomer lies in the analysis of pixel distances, the use of the Java method is recommended.
