파일 변환¶
파일을 PDF로¶
Document types supported by PyMuPDF can easily be converted to PDF by using the Document.convert_to_pdf() method. This method returns a buffer of data which can then be utilized by PyMuPDF to create a new PDF.
예제
import pymupdf
# Convert Markdown to PDF
md_doc = pymupdf.open("example.md")
pdfdata = md_doc.convert_to_pdf()
pdf_doc = pymupdf.open(stream=pdfdata)
pdf_doc.save("example.pdf")
# Convert XPS to PDF
xps = pymupdf.open("input.xps")
pdfdata = xps.convert_to_pdf()
pdf = pymupdf.open(stream=pdfdata)
pdf.save("output.pdf")
Markdown to PDF¶
As Markdown files are supported input files they can be easily converted to PDF using the Document.convert_to_pdf() method.
In the simplest case you can just open the Markdown file and call the method to get a PDF representation of the content.
Defining paper size¶
The default paper size is 400 x 600 Rect but you can specify a custom paper size if you wish, to do this just send through the Rect parameter as required, for example:
md_doc = pymupdf.open("example.md", rect=pymupdf.paper_rect("A4")) # A4 size
Defining CSS¶
By default, the Markdown content will be converted to PDF using a default CSS stylesheet. However, you can specify your own CSS stylesheet to customize the appearance of the resulting PDF. To do this, define your css and apply it.
For example, to make all h1 headers red (The single # symbol in Markdown), you could do the following:
md_doc = pymupdf.open( # open the Markdown document in A4 size
"example.md",
rect=pymupdf.paper_rect("A4")
)
css = "h1 {color:red;}"
md_doc.apply_css(css)
pdf_doc = pymupdf.open(stream=md_doc.convert_to_pdf())
pdf_doc.ez_save("red-colored-header.pdf")
참고
The support for CSS is currently limited.
Using CSS Custom Element Selectors¶
Markdown input supports custom element selectors in the CSS, so you can define your own tags in the Markdown and then refer to them in the CSS.
In this way you can specify custom styles for specific elements in the Markdown content. For example, you could define a custom tag called mytag in the Markdown and then refer to it in the CSS to make it red:
css = """
mytag {
color: red;
}
"""
And the corresponding Markdown:
# This is a header
This is some text.
<mytag>This text will be red.</mytag>
This is particularly useful for defining image sizes. For example, you could define a custom class called my_image_class in the CSS and then refer to it in the Markdown to style images:
css = """
my_image_class img {
width: 100px;
height: 100px;
}
"""
With the corresponding Markdown:
# This is a header
This is some text.
<my_image_class><img src="pie-chart.png" /></my_image_class>
Defining Fonts¶
Fonts can be defined by using the Archive (아카이브) parameter to provide a custom Archive (아카이브) containing the font files.
The fonts must exist in an archive which is provided to the Archive (아카이브) parameter when opening the Markdown file. The CSS can then refer to these fonts by their names as defined in the archive.
For example, assuming you have access to the source files for the “Comic Sans” font for all text, you could do the following:
# Global CSS instructions to use the "Comic Sans" font for all text. The font files must be provided in the archive.
css = """
@font-face {font-family: sans-serif; src: url(comic.ttf);}
@font-face {font-family: sans-serif; src: url(comicbd.ttf); font-weight: bold;}
@font-face {font-family: sans-serif; src: url(comicz.ttf); font-weight: bold; font-style: italic;}
@font-face {font-family: sans-serif; src: url(comici.ttf); font-style: italic;}
"""
archive = pymupdf.Archive("C:/Windows/Fonts") # the fonts are here
archive.add(".") # we've stored the archive image in this script's folder
md_file = "sample.md"
md_doc = pymupdf.open( # open the Markdown document
md_file,
archive=archive, # where to look for resources (fonts, images)
rect=pymupdf.paper_rect("A4"), # page dimension ISO A4
)
md_doc.apply_css(css)
PDF를 Markdown으로¶
PyMuPDF4LLM API 를 활용하여 PDF를 Markdown 표현으로 변환할 수 있습니다.
예제
import pymupdf4llm
import pathlib
md_text = pymupdf4llm.to_markdown("test.pdf")
print(md_text)
pathlib.Path("4llm-output.md").write_bytes(md_text.encode())
PDF를 SVG로¶
기술적으로 SVG 파일은 다중 페이지를 지원하지 않으므로 각 페이지를 SVG로 내보내야 합니다.
페이지의 SVG 표현을 얻으려면 Page.get_svg_image() 메서드를 사용하세요.
예제
import pymupdf
doc = pymupdf.open("input.pdf")
page = doc[0]
# Convert page to SVG
svg_content = page.get_svg_image()
# Save to file
with open("output.svg", "w", encoding="utf-8") as f:
f.write(svg_content)
doc.close()
PDF를 DOCX로¶
PyMuPDF 를 사용하여 PDF 에서 DOCX 형식으로 문서 변환을 제공하는 pdf2docx 라이브러리를 사용하세요.
예제
from pdf2docx import Converter
pdf_file = 'input.pdf'
docx_file = 'output.docx'
# convert pdf to docx
cv = Converter(pdf_file)
cv.convert(docx_file) # all pages by default
cv.close()
