Member Data Documentation

ACTIVE_COLS

Identicon::ACTIVE_COLS = (IDENTICON_ROWS + 1) / 2

staticconstexprprivate

Width from the center to the outside, for 5 columns it's 3, 6 -> 3, 7 -> 4

Definition at line 38 of file identicon.h.

COLORS

Identicon::COLORS = 2

staticconstexprprivate

Number of colors to use for the identicon

Definition at line 37 of file identicon.h.

colors

QColor Identicon::colors[COLORS]

private

Definition at line 43 of file identicon.h.

HASH_MIN_LEN

Identicon::HASH_MIN_LEN

staticconstexprprivate

Initial value:

= ACTIVE_COLS * IDENTICON_ROWS
                                      + COLORS * IDENTICON_COLOR_BYTES

Min length of the hash in bytes, 7 bytes control the color, the rest controls the pixel placement

Definition at line 39 of file identicon.h.

IDENTICON_COLOR_BYTES

Identicon::IDENTICON_COLOR_BYTES = 6

staticconstexpr

Specifies how many bytes should define the foreground color must be smaller than 8, else there'll be overflows

Definition at line 34 of file identicon.h.

IDENTICON_ROWS

Identicon::IDENTICON_ROWS = 5

staticconstexpr

Specifies how many rows of blocks the identicon should have
