How to remove hidden text in pdf file, which created with func show_pdf_page?

[Herrifly]

Hi! I am creating pdf files with important rectangles grouped, but the resulting pdf contains not only my notes, but also hidden text (of other parts of the target pdf) that I can copy and it prevents me from further processing, can I somehow leave only the visible text or create this pdf somehow Any other way? Thanks

When you use show_pdf_page(), the full original page will be present in the target - even when you use clip. We are considering to offer an option that removes source page parts that are not in clip, but you currently have to "manually" remove it yourself.
Here is a way to do that using redactions. We are creating 4 redaction rectangles representing the source page parts outside clip, execute source_page.apply_redactions() and then use show_pdf_page().

for src_page in source:
    left = src_page.rect
    left.x1 = clip.x0
    if not left.is_empty:
        src_page.add_redact_annot(left)
    right = src_page.rect
    right.x0 = clip.x1
    if not right.is_empty:
        src_page.add_redact_annot(left)
    top = src_page.rect
    top.y1 = clip.y0
    if not top.is_empty:
        src_page.add_redact_annot(left)
    btm = src_page.rect
    btm.y0 = clip.y1
    if not btm.is_empty:
        src_page.add_redact_annot(left)
    src_page.apply_redactions()  # optionally select what to remove

    tar_page.show_pdf_page(rect, src, src_page.number, clip=clip)
