Points in the coordinate plane are all governed by trigonometry and the corresponding formulas. How to calculate the new coordinates of a point that’s rotated about an axis? Note these formulas are for clockwise rotation. The following formula can be used to calculate the coordinate point in the x-y plane that has rotated by some angle (θ) about the x-axis. Enter the original coordinates and the total rotation to calculate the new coordinates. The image is rotated in a clockwise direction.Calculate the new coordinates of a point that has rotated about the z-axis of the coordinate plane.

Paste the code into a form, call InitializeBitmap from the form's constructor or Load event-handling method and associate Button1_Click with the button's Click event. This example is designed to be used with a Windows Form that contains a PictureBox named PictureBox1 and a button named Button1. The following code example demonstrates how to set the RotateFlip property of an Image and the RotateFlipType enumeration. Specifies no clockwise rotation followed by a vertical flip. Specifies no clockwise rotation followed by a horizontal and vertical flip. Specifies no clockwise rotation followed by a horizontal flip. Specifies no clockwise rotation and no flipping. Specifies a 90-degree clockwise rotation followed by a vertical flip. Specifies a 90-degree clockwise rotation followed by a horizontal and vertical flip. Specifies a 90-degree clockwise rotation followed by a horizontal flip. Specifies a 90-degree clockwise rotation without flipping. Specifies a 270-degree clockwise rotation followed by a vertical flip. Specifies a 270-degree clockwise rotation followed by a horizontal and vertical flip. Specifies a 270-degree clockwise rotation followed by a horizontal flip. Specifies a 270-degree clockwise rotation without flipping. Specifies a 180-degree clockwise rotation followed by a vertical flip. Specifies a 180-degree clockwise rotation followed by a horizontal and vertical flip. Specifies a 180-degree clockwise rotation followed by a horizontal flip. Specifies a 180-degree clockwise rotation without flipping.
