Class ColorLookupTable

java.lang.Object
  de.desy.acop.video.displayer.ColorLookupTable

Deprecated. replaced by LookUpTable

public final class ColorLookupTable
extends java.lang.Object

ColorLookup creates, prepares and maintains a false color table necessary to decode pure grayscale image data to true color display. Three false color tables (mappings) are supported at the moment:

• PITZ false color (was invented at PITZ Video System v2, Velizar Miltchev)
• MATLAB jet false color (taken from Matlab)
• GRAYSCALE simple grayscale conversion

An important criteria to mention is that these mappings support scaling to physical and effective bits per pixel settings. For example if source grayscale data is 16bpp physically encoded (for performance reason) but only 12 of these bits are effectively used, the false color table is designed to support 0 as darkest and 4195 (12 bit max) as brightest value. All other value (for 16 bit: 4096 to 65535) are encoded in magenta to easily detect them as being illegal. In comparison to that, the output format is always java TYPE_INT_ARGB for sake of simplicity.
The main use is to generate a 1-dimensional false-color-mapping table that accepts as index any physically valid grayscale number and returns the matched pixel ready for being placed to the output drawing buffer.
