Enumeration Type Documentation

enum iptk::BitDepth

Enumerated data type to specify the pixel depth of the image. GRAY_SCALE indicates that the image is an 8-bit gary-scale image and RGB indicates that the image is a 24-bit RGB image. Enumeration values: GRAY_SCALE  Specifies a gray-scale image. RGB  Specifies an RGB image.

enum iptk::ColourLayer

Enumerated data type for differentiating different colour layers of an image. INTENSITY_LAYER is meaningfull layer only for images with BitDepth GRAY_SCALE. RED_LAYER, GREEN_LAYER, BLUE_LAYER are meaningfull only for images with BitDepth RGB. Enumeration values: INTENSITY_LAYER  Specifies the intensity layer of a gray-scale image. RED_LAYER  Specifies the red layer of an RGB image. GREEN_LAYER  Specifies the green layer of an RGB image. BLUE_LAYER  Specifies the blue layer of an RGB image.

enum iptk::MaskType

An enumerated type to denote the type of Mask being used. The name of the enumeration denotes the kind of the mask. Enumeration values: GAUSSIAN_MASK  Denotes a Gaussian Mask. LAPLACIAN_MASK  Denotes a Laplacian Mask. RECTANGULAR_MASK  Denotes a Rectangular Mask.
