PDF

Work PDFs in the sandbox with preinstalled Python libs. Pick the library by task:

  • Extract text/tables/layout/word-coordinates → pdfplumber; quick raw text or page ops → pypdf.
  • Merge / split / rotate / crop / watermark / encrypt / metadata → pypdf.
  • Fill forms → pypdf (fillable AcroForm fields) or annotation overlay (flat forms).
  • Create from scratch → reportlab.

Write complete Python source and run it via code_execution. Save outputs to the workspace dir. After execution, refer to the PDF exactly as the Generated artifacts list names it. Use exec only for a genuinely shell-only command; never put this source in python -c or a heredoc. Preserve an explicitly requested quantity (such as 500 words) and verify the count in the output before finishing. If execution fails or the artifact is missing, diagnose stderr/root cause and change strategy; do not retry identical code or reduce the requested scope without asking.

Extract text and tables (pdfplumber)

import pdfplumber

with pdfplumber.open("in.pdf") as pdf:
    for i, page in enumerate(pdf.pages, 1):
        print(f"--- page {i} ---")
        print(page.extract_text() or "")  # layout-aware text
        for t in page.extract_tables():  # list of tables; each is list[row]
            for row in t:
                print(row)

Tables → DataFrame/Excel:

import pdfplumber, pandas as pd

frames = []
with pdfplumber.open("in.pdf") as pdf:
    for page in pdf.pages:
        for t in page.extract_tables():
            if t and len(t) > 1:
                frames.append(pd.DataFrame(t[1:], columns=t[0]))
if frames:
    pd.concat(frames, ignore_index=True).to_excel("tables.xlsx", index=False)

Messy tables: pass strategies, or crop a region with page.within_bbox((x0, top, x1, bottom)) first:

ts = {
    "vertical_strategy": "lines",
    "horizontal_strategy": "lines",
    "snap_tolerance": 3,
    "intersection_tolerance": 15,
}
page.extract_tables(ts)

For very large PDFs where you only need raw text, pypdf's page.extract_text() is lighter.

Scanned / image-only PDFs (be honest)

If extract_text() returns empty or garbage (e.g. (cid:NN) runs) the page is scanned. No OCR engine (tesseract) is installed and network is off, so you cannot recover that text. Say so plainly and stop — do not fabricate content or attempt pip install.

Merge / split / rotate / crop / metadata (pypdf)

from pypdf import PdfReader, PdfWriter

# Merge
w = PdfWriter()
for f in ["a.pdf", "b.pdf"]:
    for p in PdfReader(f).pages:
        w.add_page(p)
w.write("merged.pdf")

# Split: one file per page
r = PdfReader("in.pdf")
for i, p in enumerate(r.pages, 1):
    w = PdfWriter()
    w.add_page(p)
    w.write(f"page_{i}.pdf")

# Rotate page 0 by 90 degrees clockwise
r = PdfReader("in.pdf")
w = PdfWriter()
r.pages[0].rotate(90)
w.add_page(r.pages[0])
w.write("rotated.pdf")
  • Metadata: PdfReader("in.pdf").metadata (.title, .author, ...).
  • Crop: set page.mediabox.left/bottom/right/top (points, origin y=0 at bottom).
  • Encrypt: w = PdfWriter(clone_from=PdfReader("in.pdf")); w.encrypt("userpw", "ownerpw"); w.write("enc.pdf").
  • Decrypt: r = PdfReader("enc.pdf"); r.decrypt("pw") if r.is_encrypted, then read/copy pages.

Watermark (stamp one page over every page):

from pypdf import PdfReader, PdfWriter

wm = PdfReader("stamp.pdf").pages[0]
r = PdfReader("in.pdf")
w = PdfWriter()
for p in r.pages:
    p.merge_page(wm)
    w.add_page(p)
w.write("stamped.pdf")

Create PDFs (reportlab)

Flowing document (preferred for text/reports/tables — handles pagination):

from reportlab.lib.pagesizes import letter
from reportlab.lib.styles import getSampleStyleSheet
from reportlab.lib import colors
from reportlab.platypus import SimpleDocTemplate, Paragraph, Spacer, Table, TableStyle

styles = getSampleStyleSheet()
story = [
    Paragraph("Report Title", styles["Title"]),
    Spacer(1, 12),
    Paragraph("Body text. " * 20, styles["Normal"]),
]
data = [["Product", "Q1", "Q2"], ["Widgets", "120", "135"]]
tbl = Table(data)
tbl.setStyle(
    TableStyle(
        [
            ("BACKGROUND", (0, 0), (-1, 0), colors.grey),
            ("TEXTCOLOR", (0, 0), (-1, 0), colors.whitesmoke),
            ("GRID", (0, 0), (-1, -1), 0.5, colors.black),
        ]
    )
)
story += [Spacer(1, 12), tbl]
SimpleDocTemplate("out.pdf", pagesize=letter).build(story)

Absolute placement (labels at fixed coordinates): use canvas.Canvas("out.pdf", pagesize=letter), c.drawString(x, y, "...") (origin bottom-left, points), c.showPage() per page, c.save().

Non-Latin text (Chinese / Japanese / Korean, Cyrillic, …)

reportlab's built-in fonts (Helvetica/Times/Courier) carry zero CJK glyphs, so any 中文/日本語/한국어 renders as empty boxes (□) baked permanently into the PDF. reportlab never auto-discovers system fonts — you MUST register a font that has the glyphs and set it on every style. Whenever the document may contain non-Latin text, register a CJK font first (it also covers Latin, so it is safe to use as the only font):

import os
from reportlab.pdfbase import pdfmetrics
from reportlab.pdfbase.ttfonts import TTFont


def register_cjk_font(name="CJK"):
    # TrueType ONLY — reportlab cannot embed CFF/OpenType outlines, so a .otf
    # like Noto Sans CJK fails with "postscript outlines are not supported".
    for path in [
        "/usr/share/fonts/truetype/wqy/wqy-zenhei.ttc",  # Linux sandbox (fonts-wqy-zenhei)
        "/usr/share/fonts/truetype/wqy/wqy-microhei.ttc",
        "/System/Library/Fonts/STHeiti Light.ttc",  # macOS
        "/System/Library/Fonts/Hiragino Sans GB.ttc",
        "/System/Library/Fonts/Supplemental/Songti.ttc",
        "/System/Library/Fonts/Supplemental/Arial Unicode.ttf",
        "C:/Windows/Fonts/msyh.ttc",  # Windows
    ]:
        if os.path.exists(path):
            try:
                pdfmetrics.registerFont(TTFont(name, path, subfontIndex=0))
                return name
            except Exception:
                continue
    raise RuntimeError("No CJK-capable TrueType font found — do not emit tofu; say so.")


font = register_cjk_font()
styles = getSampleStyleSheet()
for s in styles.byName.values():  # make the CJK font the default everywhere
    s.fontName = font
# Tables don't read the stylesheet — set the font in the TableStyle too:
#   ("FONTNAME", (0, 0), (-1, -1), font)
# Canvas: c.setFont(font, size) before every drawString.

If register_cjk_font raises (no font on the host), do not ship a tofu PDF — tell the user the sandbox lacks a CJK font instead of producing garbage.

Gotcha: even with a good font, reportlab still needs markup for subscripts/superscripts. In Paragraph use Paragraph("H<sub>2</sub>O", styles["Normal"]), x<super>2</super>.

Markdown/HTML → PDF needs an external converter (soffice/pandoc) that is usually absent — command -v soffice / command -v pandoc and degrade to building the PDF directly with reportlab if neither is present.

Fill forms (pypdf)

First detect whether the PDF has real fillable (AcroForm) fields:

from pypdf import PdfReader

fields = PdfReader("form.pdf").get_fields()
print("fillable" if fields else "flat (no fields)")

Fillable — inspect field names/types, then fill and write:

from pypdf import PdfReader, PdfWriter

r = PdfReader("form.pdf")
for name, f in r.get_fields().items():
    print(name, f.get("/FT"), f.get("/_States_"))  # /Tx text, /Btn checkbox/radio, /Ch choice

w = PdfWriter(clone_from=r)
values = {"first_name": "Bart", "agree": "/Yes"}  # checkbox/radio: use its on-state, NOT True/False
for page in w.pages:
    w.update_page_form_field_values(page, values, auto_regenerate=False)
w.set_need_appearances_writer(True)  # force viewers to render the values
w.write("filled.pdf")

Checkbox/radio values are on-state strings, not booleans — read the field's /_States_ (e.g. /Yes, /On); /Off clears it.

Flat form (no fields) — overlay text with FreeText annotations at PDF coordinates. Get real coordinates from the layout with pdfplumber instead of guessing:

import pdfplumber

with pdfplumber.open("form.pdf") as pdf:
    pg = pdf.pages[0]
    for wd in pg.extract_words():  # each has x0, top, x1, bottom (TOP-left origin!)
        print(wd["text"], wd["x0"], wd["top"])
    for rc in pg.rects:  # small squares are likely checkboxes
        print("rect", rc["x0"], rc["top"], rc["x1"], rc["bottom"])

pdfplumber top is measured from the page top; pypdf rects are bottom-left, so convert: pdf_y = page_height - top. Place text just right of the matching label:

from pypdf import PdfReader, PdfWriter
from pypdf.annotations import FreeText

r = PdfReader("form.pdf")
w = PdfWriter()
w.append(r)
h = float(r.pages[0].mediabox.height)
top = 700  # pdfplumber 'top' of the label's row
w.add_annotation(
    page_number=0,
    annotation=FreeText(
        text="Smith",
        rect=(255, h - top - 14, 720, h - top),  # (x0, y0, x1, y1)
        font="Helvetica",
        font_size="10pt",
        font_color="000000",
        border_color=None,
        background_color=None,
    ),
)
w.write("filled.pdf")

Verify: re-open the output and re-read get_fields() values (fillable) or re-extract text (overlay) to confirm the values landed.

Page → image rendering (PyMuPDF)

PyMuPDF (imported as fitz, preinstalled) rasterizes pages — useful to inspect a PDF visually or to hand a page to an image-capable step. No external tools needed (poppler / pdf2image are absent; don't reach for them).

import fitz  # PyMuPDF

doc = fitz.open("in.pdf")
for i, page in enumerate(doc, 1):
    page.get_pixmap(dpi=150).save(f"page_{i}.png")  # higher dpi = sharper + larger

fitz also extracts text (page.get_text()) and can render a sub-region via page.get_pixmap(clip=fitz.Rect(x0, y0, x1, y1)). It does not OCR — a rendered scanned page is still just pixels (see Scanned PDFs above).

# PDF

Work PDFs in the sandbox with preinstalled Python libs. Pick the library by task:

- **Extract** text/tables/layout/word-coordinates → `pdfplumber`; quick raw text or page ops → `pypdf`.
- **Merge / split / rotate / crop / watermark / encrypt / metadata** → `pypdf`.
- **Fill forms** → `pypdf` (fillable AcroForm fields) or annotation overlay (flat forms).
- **Create from scratch** → `reportlab`.

Write complete Python source and run it via `code_execution`. Save outputs to the workspace dir.
After execution, refer to the PDF exactly as the Generated artifacts list names it. Use `exec` only for a genuinely shell-only command; never put this source in `python -c` or a heredoc.

        print(page.extract_text() or "")  # layout-aware text
        for t in page.extract_tables():  # list of tables; each is list[row]
            for row in t:

```

r = PdfReader("in.pdf")
w = PdfWriter()
r.pages[0].rotate(90)
w.add_page(r.pages[0])
w.write("rotated.pdf")
```

- **Metadata**: `PdfReader("in.pdf").metadata` (`.title`, `.author`, ...).
- **Crop**: set `page.mediabox.left/bottom/right/top` (points, origin y=0 at bottom).

  1. 1阅读来源，确认输入、预期输出、依赖和权限。
  2. 2先让 Agent 提出计划，批准环境配置和费用，再进行隔离的小规模测试。
  3. 3检查输出和变更文件，只报告实际执行结果，并保留来源版本以便复现。

请在来源中核实依赖、API 密钥及第三方费用。公开仓库不代表所有服务免费。
