Circular Image Constraint

This rules check that an image is enclosed within circle, ensuring that the background is transparent. Hence, this requires the image format to support transparency.

Detailed description

This rule, named "Circular Image Constraint," ensures that an image is enclosed within a circular boundary. The primary condition is that the image must have a transparent background, necessitating support for transparency in the image format. This rule is particularly relevant for images that are intended to be displayed within circular frames or icons.

Correction

The correction process involves identifying pixels outside the circular boundary and setting their alpha channel (transparency) to 0. This correction ensures that the image conforms to the circular constraint.

Additionally, considerations are made for cases where the image is not square, providing flexibility in handling various image aspect ratios. To accommodate non-square images, the algorithm considers the minimum dimension (width or height) as the radius for the circular boundary. This modification ensures that the circular constraint is applied appropriately, even when dealing with images of varying aspect ratios.

Creator tips

• Ensure that the image has a transparent background to comply with the circular constraint.
• Utilize image editing tools to crop images into a circular shape.
