zFilter is a postpocessing WebGL shader plugin for dynamic effects on your panorama image. It allows you to add visual effects for startup intros, scene changes, information popups, etc. Setting or tweening simple plugin attributes adjusts the brightness, saturation or blurs your image!
Note: Blurring is done by an intelligent, performance optimized algorithm, but it needs more passes (WebGL shaders), the stronger you're blurring the image. For devices with low performance you should avoid high blur values.
32bit ARGB values consist of 4 bytes, each with a range of hexadecimal 0x00 to 0xff. Normally 32bit ARGB values are used for colors and are mapped to alpha, red, green and blue, but zFilter can also map them to other parameters as in the vignettecolor attibute. The byte to shader parameter mapping is described above for each attribute.
You can set 32bit ARGB values by Numbers or Strings in decimal or hex format
Reading a 32bit ARGB value returns a String in hexadecimal format
