BitMap

Boolean matrix.

A two-dimensional array of boolean values, can be used to efficiently store a binary matrix (every matrix element takes only one bit) and query the values using natural cartesian coordinates.

Functions

_getData Dictionary _getData()
_setData void _setData(Dictionary arg0)
create void create(Vector2 size): Creates a bitmap with the specified size, filled with false.
createFromImageAlpha void createFromImageAlpha(Image image, double threshold): Creates a bitmap that matches the given image dimensions, every element of the bitmap is set to false if the alpha value of the image at that position is equal to threshold or less, and true in other case.
getBit bool getBit(Vector2 position): Returns bitmap's value at the specified position.
getSize Vector2 getSize(): Returns bitmap's dimensions.
getTrueBitCount long getTrueBitCount(): Returns the amount of bitmap elements that are set to true.
growMask void growMask(long pixels, Rect2 rect): Applies morphological dilation to the bitmap. The first argument is the dilation amount, Rect2 is the area where the dilation will be applied.
opAssign typeof(null) opAssign(typeof(null) n)
opEquals bool opEquals(BitMap other)
opEquals bool opEquals(typeof(null) n)
opaqueToPolygons Array opaqueToPolygons(Rect2 rect, double epsilon)
setBit void setBit(Vector2 position, bool bit): Sets the bitmap's element at the specified position, to the specified value.
setBitRect void setBitRect(Rect2 rect, bool bit): Sets a rectangular portion of the bitmap to the specified value.
toHash size_t toHash()
