Detailed Description

Color pixel value coded as 4 unsigned 8-bit integers (red, green, blue and alpha components).

This class is suited to handle the Windows 32-bit ARGB color format. The pixel values are coded on 32 bits, leaving 256 possible levels per color component (red, green, blue), as well as 8 more bits for an alpha channel.

C0

uint8_t eVision::EC24A::C0

The value of the first component of the pixel (red channel).

C1

uint8_t eVision::EC24A::C1

The value of the second component of the pixel (green channel).

C2

uint8_t eVision::EC24A::C2

The value of the third component of the pixel (blue channel).
