ReduceToBilevelThreshold |

GrayIntegerImage to a
BilevelImage by setting all values below
a certain threshold value to black and everything else to white. |
RGBToGrayConversion |
Converts RGB color images (both truecolor and paletted) to grayscale images.
|
Classes to convert images to a lower
color type.
Usually, that conversion is lossy (e.g. from RGB truecolor to
grayscale, or from shades of gray to black and white).
However, the AutoDetectColorType
class reduces only if
an image can be converted to a lower
color type
without losing information.
This is the inverse operation to color promotion,
provided by another package.
