hide元素自始可用
Hides content without affecting layout.
The hide function allows you to hide content while the layout still “sees” it. This is useful for creating blank space that is exactly as large as some content.
Example
Hello Jane \
#hide[Hello] Joe
Redaction
This function may also be useful for redacting content as its arguments are neither present visually nor accessible to Assistive Technology. That said, there can be some traces of the hidden content (such as a bookmarked heading in the PDF’s Document Outline).
Note that, depending on the circumstances, it may be possible for content to be reverse engineered based on its size in the layout. We thus do not recommend using this function to hide highly sensitive information.
