Detailed Description

a black-and-wite photo stored as inline constant data (in ROM)

The class inline_bw_photo is a concrete child of the photo class. It stores the colors of the pixels in an array of constant data. Inline_wb_photo uses 1 bit per pixel (inline_rgb_photo uses 3 bytes per pixel). The inline.py tool can be used to convert a .jpg or .bmp file into the .h and .cpp file for an inline_bw_photo. This is likely to be the only way you will instantiate this class.

Each pixel can either be on or off. An 'on' pixel returns the fg colcor (default: color::black), an off pixel returns the bg colcor (deafult: color::white).

The inline_bw_photo class can be used instead of inline_rgb_photo to store a picture in a more compact form. It is also used by the library to store fonts.

Constructor & Destructor Documentation

bmptk::graphics::inline_bw_photo::inline_bw_photo ( const vector  size, const unsigned char *  data  )

inline

create an inline_bw_photo object

Parameters

size	the size of the photo
data	the pixel data The data contains one bit per pixel, x address varies fastest. No filling except (when needed) the last byte. The bits within a byte are stored LSB first.
