Pseudo Code for Drawing a Tree

This pseudo code represents the functionality of a tree-drawing function using graphical commands in a hypothetical programming environment.

Initialization

1. Set up the drawing environment:
   • Call penup() to lift the pen off the drawing surface.
   • Move the pen to the starting coordinates (250, -320) using goto(250, -320).
   • Set the pen size to 10 using pensize(10).
   • Set the pen color to black using pencolor('black').
   • Set the fill color for the tree trunk to a shade of salmon using fillcolor('salmon4').
   • Make the pen operational again with pendown().

Draw the Tree Trunk

2. Begin filling the trunk shape:
   • Call begin_fill() to start filling the shape.
   • Set the direction to 87.5 degrees with setheading(87.5).
   • Move the pen forward by 295 units using forward(295).
   • Move the pen backward by 295 units using backward(295).
   • Set the direction to 0 degrees (facing right) with setheading(0).
   • Move the pen forward by 100 units using forward(100).
   • Set the direction to 92.5 degrees with setheading(92.5).
   • Move the pen forward by 295 units using forward(295).
   • Turn left 90 degrees using left(90).
   • Move forward by 78 units using forward(78).
   • Call end_fill() to complete filling the trunk.

Draw the Tree Leaves (Top)

3. Position for drawing leaves:
   • Call penup() and move to (285, 160) using goto(285, 160).
   • Make the pen operational with pendown().
   • Set the fill color to a green shade using fillcolor('green4').
   • Call begin_fill() to start filling the leaf shape.
   • Draw a full circle with radius 100 using circle(100, extent = 360).
   • Call end_fill() to complete filling the leaves.

Draw Red and Orange Decorations

4. Adding red and orange decorations:

   • Move to (350, 20) using penup() followed by goto(350, 20).
   • Set pen direction to 45 degrees using setheading(45).
   • Draw a red decoration:
     • Set the fill color to red with fillcolor('red').
     • Start filling with begin_fill().
     • Draw a semicircle with radius 45 and extent 90 using circle(45, 90).
     • Draw a smaller circle with radius 12.6 and extent 90 using circle(12.6, 90).
     • Call end_fill() to complete the red decoration.
   • Draw an orange decoration:
     • Set the fill color to orange with fillcolor('orange').
     • Start filling with begin_fill().
     • Repeat drawing the same two circles as above.
     • Call end_fill() to complete the orange decoration.

5. Repeat for additional orange and red decorations:

   • Repeat the above step with the pen moved to (280, 0) and then to (300, 70), ensuring the same shapes and colors are used.

Summary of Logic

• The function creates a tree by drawing a trunk and leaves along with decorative shapes around the base and top of the tree, utilizing fill colors for visual appeal.

This pseudo code summarizes the logic of the provided drawing function in a clear and structured format suitable for understanding and implementation.
