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.
Returns an image of the same size as the bitmap and with a [enum Image.Format] of type [constant Image.FORMAT_L8]. [code]true[/code] bits of the bitmap are being converted into white pixels, and [code]false[/code] bits into black.
Creates a bitmap with the specified size, filled with [code]false[/code].
Creates a bitmap that matches the given image dimensions, every element of the bitmap is set to [code]false[/code] if the alpha value of the image at that position is equal to [param threshold] or less, and [code]true[/code] in other case.
Returns bitmap's value at the specified position.
Returns bitmap's value at the specified position.
Returns bitmap's dimensions.
Returns the number of bitmap elements that are set to [code]true[/code].
Applies morphological dilation or erosion to the bitmap. If [param pixels] is positive, dilation is applied to the bitmap. If [param pixels] is negative, erosion is applied to the bitmap. [param rect] defines the area where the morphological operation is applied. Pixels located outside the [param rect] are unaffected by [method grow_mask].
Creates an [Array] of polygons covering a rectangular portion of the bitmap. It uses a marching squares algorithm, followed by Ramer-Douglas-Peucker (RDP) reduction of the number of vertices. Each polygon is described as a [PackedVector2Array] of its vertices. To get polygons covering the whole bitmap, pass: [codeblock] Rect2(Vector2(), get_size()) [/codeblock] [param epsilon] is passed to RDP to control how accurately the polygons cover the bitmap: a lower [param epsilon] corresponds to more points in the polygons.
Resizes the image to [param new_size].
Sets the bitmap's element at the specified position, to the specified value.
Sets a rectangular portion of the bitmap to the specified value.
Sets the bitmap's element at the specified position, to the specified value.
