C# Класс ProtoTurtle.BitmapDrawing.BitmapDrawingExtensions

A extension class for UnityEngine.Texture2D that provides a bitmap drawing API. Provides drawing methods line Line, Circle, Rectangle etc. This class uses a convention of having the 0,0 point at the left-top corner!

Открытые методы

Метод	Описание
DrawCircle ( this texture, int x, int y, int radius, Color color ) : void	Draws a circle with the midpoint being x0, x1. Implementation of Bresenham's circle algorithm
DrawFilledCircle ( this texture, int x, int y, int radius, Color color ) : void	Draws a filled circle with the midpoint being x0, x1. Implementation of Bresenham's circle algorithm
DrawFilledRectangle ( this texture, Rect rectangle, Color color ) : void	Fills the given rectangle area with a solid color.
DrawLine ( this texture, Vector2 start, Vector2 end, Color color ) : void
DrawLine ( this texture, Vector3 start, Vector3 end, Color color ) : void
DrawLine ( this texture, int x0, int y0, int x1, int y1, Color color ) : void	Draws a line between two points. Implementation of Bresenham's line algorithm.
DrawPixel ( this texture, int x, int y, Color color ) : void	Draws a pixel just like SetPixel except 0,0 is the left top corner.
DrawPixel ( this texture, int x, int y, int width, int height, Color color ) : void	Draws a pixel just like SetPixel except 0,0 is the left top corner. Takes the width and height as parameters - faster for calling this in a loop.
DrawRectangle ( this texture, Rect rectangle, Color color ) : void	Draws a rectangle
FloodFill ( this texture, int startX, int startY, Color newColor ) : void	Starts a flood fill at point startX, startY. This is a pretty slow flood fill, biggest bottle neck is comparing two colors which happens a lot. Should be a way to make it much faster. O(n) space. n = width*height - makes a copy of the bitmap temporarily in the memory
