I am writing to inquire about how to determine the z-index values for elements on a specific page of a PDF document. Understanding the stacking order of elements in the z-axis is crucial for comprehending the layout and visual hierarchy within the PDF.
At times, I encounter difficulties in accurately identifying the z-index values of elements, especially when working with complex PDF files. Could you please provide guidance or suggest any tools or techniques that would assist me in determining the z-index values of all individual elements on a PDF page?
Thank you for your support, and I look forward to your response.
