How to draw pineapple ring and output it as bitmap

Question

This is pineapple ring I wanted to draw using VB code:

Imagine the background color is black. Each segment must be same size. The line color can be same for practice purpose. The final image have to output to bitmap file.

For those who have no idea how pineapple ring looks like, here is the image as reference:

Answer 1

Thank you for reaching out.

The code draws onto a Bitmap using a Graphics object:

• Create a blank bitmap (600×600)
• Draw two circles (outer + inner) centered on the image
• Divide the ring into 8 equal slices By drawing 8 lines spaced 45° apart
• Apply colors to the divider lines Cycling through Yellow → Pink → Blue
• Save the finished bitmap to the user’s Desktop (pineapple_ring_step6.bmp)

Angles are calculated in radians:

angle = i * (Math.PI / 4)

This guarantees every slice is exactly the same size.

Answer 2

Here is the sample output screenshot:

The code I was using:

`Private Sub PictureBox1_Paint(sender As Object, e As PaintEventArgs) Handles PictureBox1.Paint`

'NOTE: add PictureBox control to winform and set its background color to darkgreen

'PictureBox1.BackColor = Color.DarkGreen

Dim x_value As Int32

Dim y_value As Int32

x_value = 50

y_value = 50

Dim x_value_b As Int32

Dim y_value_b As Int32

x_value_b = 100

y_value_b = 100

Dim pieBounds As New Rectangle(x_value, y_value, 200, 200)

' Define the start angle and sweep angle in degrees

Dim startAngle As Single = 0

Dim sweepAngle As Single = 360

Dim count As Int32

Dim degree As Single

Dim pen_a As New Pen(Color.Black) 'this pen is used for drawing the outer ring

degree = -7 'set the first segment's degree position

For count = 1 To 8 'divide 360 degree to 8 segments

degree = degree + 45 'each segment has 45 degree

pen_a.Dispose() 'destroy previous instance

pen_a = New Pen(Color.Blue) 'can change color for each segment, if desire

e.Graphics.DrawPie(pen_a, pieBounds, degree, 45)

Next

'now we draw the inner ring

Dim pieBounds_b As New Rectangle(x_value_b, y_value_b, 100, 100)

Dim brush_b As New SolidBrush(Color.DarkGreen)

'draw the circle (fill in color)

e.Graphics.FillPie(brush_b, pieBounds_b, startAngle, sweepAngle)

brush_b.Dispose()

'draw the circle outline

Dim pen_d As New Pen(Color.Black)

e.Graphics.DrawEllipse(pen_d, pieBounds_b)

pen_d.Dispose()

End Sub
