Package com.twelvemonkeys.imageio.color
Class ColorSpaces
java.lang.Object
com.twelvemonkeys.imageio.color.ColorSpaces
A helper class for working with ICC color profiles and color spaces.
Standard ICC color profiles are read from system-specific locations for known operating systems.
Color profiles may be configured by placing a property-file
com/twelvemonkeys/imageio/color/icc_profiles.properties
on the classpath, specifying the full path to the profiles.
ICC color profiles are probably already present on your system, or
can be downloaded from
ICC,
Adobe or other places.
