Las anotaciones rectangulares proporcionan una forma precisa de resaltar secciones dentro de un PDF, con colores, bordes y transparencia ajustables.

Rectangle annotations in PDF controls allow users to highlight specific areas within a document by drawing rectangular shapes.

Typically, rectangle annotations support customization options such as border color, fill color, opacity, and line thickness, enabling users to tailor them to their needs. Many PDF viewer components also provide interactive features, such as the ability to move, resize, or delete annotations, ensuring flexibility in document review and collaboration workflows.
