Method Summary

BitMaskEnumerator	enumerator() Bit-mask enumeration.
boolean	getPixel(int x, int y) Returns the pixel's value.
void	init() Bit-mask re-initialization (keeps current bitmask size - if the size is relevant).
void	init(int x, int y) Bit-mask (re-)initialization.
void	setHLine(int x1, int x2, int y) Sets the horizontal line from [min(x1,x2),y] to [max(x1,x2)-1,y].
void	setPixel(int x, int y) Sets the given pixel's value to true = "painted".

Method Detail

init

void init(int x,
          int y)

Bit-mask (re-)initialization.

Parameters:

x - Width of a new bitmask.

y - Height of a new bitmask.

init

void init()

Bit-mask re-initialization (keeps current bitmask size - if the size is relevant).

setPixel

void setPixel(int x,
              int y)

Sets the given pixel's value to true = "painted". Accepts current binary set operation.

Parameters:

x - X coordinate of a pixel.

y - Y coordinate of a pixel.

getPixel

boolean getPixel(int x,
                 int y)

Returns the pixel's value.

Parameters:

x - X coordinate of a pixel.

y - Y coordinate of a pixel.

Returns:

Pixel value (false for off-canvas access).

setHLine

void setHLine(int x1,
              int x2,
              int y)

Sets the horizontal line from [min(x1,x2),y] to [max(x1,x2)-1,y]. Accepts current binary set operation.

Parameters:

x1 - X coordinate of the starting pixel.

x2 - X coordinate of the first pixel after the line.

y - Common Y coordinate of the line.

enumerator

BitMaskEnumerator enumerator()

Bit-mask enumeration.

Returns:

The BitMaskEnumerator object instance.
