For large language models that are compatible with the OpenAI API but not listed in the table above, you can set environment variables using the same method outlined for OpenAI in the table.
Use -s service
or -s service:model
to specify service:
pdf2zh example.pdf -s openai:gpt-4o-mini
Or specify model with environment variables:
set OPENAI_MODEL=gpt-4o-mini
pdf2zh example.pdf -s openai
Use regex to specify formula fonts and characters that need to be preserved:
pdf2zh example.pdf -f "(CM[^RT].*|MS.*|.*Ital)" -c "(\(|\||\)|\+|=|\d|[\u0080-\ufaff])"
Preserve Latex
, Mono
, Code
, Italic
, Symbol
and Math
fonts by default:
pdf2zh example.pdf -f "(CM[^R]|MS.M|XY|MT|BL|RM|EU|LA|RS|LINE|LCIRCLE|TeX-|rsfs|txsy|wasy|stmary|.*Mono|.*Code|.*Ital|.*Sym|.*Math)"
Use -t
to specify how many threads to use in translation:
pdf2zh example.pdf -t 1
Use --prompt
to specify which prompt to use in llm:
pdf2zh example.pdf --prompt prompt.txt
example prompt.txt
[
{
"role": "system",
"content": "You are a professional,authentic machine translation engine.",
},
{
"role": "user",
"content": "Translate the following markdown source text to ${lang_out}. Keep the formula notation {{v*}} unchanged. Output translation directly without any additional text.\nSource Text: ${text}\nTranslated Text:",
},
]
In custom prompt file, there are three variables can be used.

---|---|
lang_in |
input language |
lang_out |
output language |
text |
text need to be translated |
Use --authorized
to specify which user to use Web UI and custom the login page:
pdf2zh example.pdf --authorized users.txt auth.html
example users.txt Each line contains two elements, username, and password, separated by a comma.

user1,password1
user2,abc123
guest,guest123
test,test123
example auth.html
