"content": "<h2>Rotate Image Effect</h2>\n<p>Rotating an image involves transforming the position of its pixels around a central point. The rotation effect can be applied by various angles, such as 90, 180, 270 degrees, or any arbitrary angle. Understanding how pixels are affected during these transformations is essential for implementing the rotation effect.</p>\n<h3>90-Degree Rotation</h3>\n<p>When rotating an image by 90 degrees clockwise, each pixel in the image is moved to a new position where its coordinates are swapped and adjusted for the new dimensions.</p>\n<p>For an image of width \\( w \\) and height \\( h \\), the pixel at position \\( (x, y) \\) will be moved to \\( (y, w - 1 - x) \\).</p>\n<p>Example:</p>\n<p>Original position: \\( (x, y) \\)<br>New position: \\( (y, w - 1 - x) \\)</p>\n<h3>180-Degree Rotation</h3>\n<p>When rotating an image by 180 degrees, each pixel in the image is moved to a new position where both its horizontal and vertical coordinates are flipped.</p>\n<p>For an image of width \\( w \\) and height \\( h \\), the pixel at position \\( (x, y) \\) will be moved to \\( (w - 1 - x, h - 1 - y) \\).</p>\n<p>Example:</p>\n<p>Original position: \\( (x, y) \\)<br>New position: \\( (w - 1 - x, h - 1 - y) \\)</p>\n<h3>270-Degree Rotation</h3>\n<p>When rotating an image by 270 degrees clockwise (or 90 degrees counterclockwise), each pixel in the image is moved to a new position where its coordinates are swapped and adjusted for the new dimensions.</p>\n<p>For an image of width \\( w \\) and height \\( h \\), the pixel at position \\( (x, y) \\) will be moved to \\( (h - 1 - y, x) \\).</p>\n<p>Example:</p>\n<p>Original position: \\( (x, y) \\)<br>New position: \\( (h - 1 - y, x) \\)</p>\n<h3>Arbitrary Angle Rotation</h3>\n<p>For rotating an image by an arbitrary angle \\( \\theta \\), the position of each pixel is transformed using rotation matrices. The new coordinates \\( (x', y') \\) for a pixel at \\( (x, y) \\) are computed as:</p>\n<p>\\( x' = x \\cos(\\theta) - y \\sin(\\theta) \\)<br>\\( y' = x \\sin(\\theta) + y \\cos(\\theta) \\)</p>\n<p>These transformations ensure that the image is accurately rotated by repositioning each pixel to its correct location based on the specified angle.</p>",
