Rabit

This project implements a simple API of turtle to draw line, rectangle, circle, text and convert the process into gif.

Install

• Install the package.

pip3 install rabit

• Install python-tk.

Usage

Rabit splits the drawing board into grids x grids. To create a Rabit object, you should choose the grids (in a row/column) you want to split and the size(default is 600) of drawing board.

import rabit

# The first argument is the number of grids in a row/column.
# The second argument is the size of the drawing board.
rabit = rabit.Rabit(11, 600)

Yuu can draw rectangle with draw_rect(row, col, rows=1, cols=1, color="black").

• row: row of the left up corner of the rectangle
• col: column of the left up corner of the rectangle
• rows: length of the rectangle
• cols: width of the rectangle
• color: line color

Yuu can paint rectangle with paint_rect(row, col, rows=1, cols=1, color="black", cover=Flase).

• row: row of the left up corner of the rectangle
• col: column of the left up corner of the rectangle
• rows: length of the rectangle
• cols: width of the rectangle
• color: line color
• cover: if cover the text on it

Yuu can draw text with draw_text(row, col, text, color="black", font=("Times", 24)).

• row: row of the text
• col: column of text
• text: text
• color: text color
• font: text font

Yuu can draw line with draw_line(from_row, from_col, to_row, to_col, color="black") .

• from_row: row of start point
• from_col: column of start point
• to_row: row of end point
• to_col: column of end point
• color: line color

You can convert the drawing process into gif with convert2gif(func, fps_for_eps, fps_for_gif).The conversion can split into two steps:

• Capturing pictures at a certain rate while drawing.
• convert all pictures(.eps) into a gif at a certain FPS by imageio.

import rabit

def your_draw_function():
  ...

# The first argument is the name of your draw function.
# The second argument is the FPS(or rate) of the capturing process.
# The third argument is the FPS of the final gif.
rabit.convert2gif(your_draw_function, 10, 5)

There are other functions you can use:

• speed(speed): set the drawing speed
• pensize(pensize): set the pensize
• begin_hide(): hide the following drawing animation
• end_hide(): end of the hiding
• hold(): don't close the window after the drawing

Examples

There is an example in the example directory.

The converted gif is:
