try:
document1 = aw.Document("自訂格式(電商匯入中心)11.pdf")
save_options = aw.saving.MarkdownSaveOptions()
save_options.image_resolution = 150
document1.save(f"自訂格式(電商匯入中心)11.md", save_options)

memory use :
When converting a PDF to Markdown using Aspose.Words, you may encounter high memory usage, especially with large documents. To help mitigate this issue, you can enable memory optimization in the MarkdownSaveOptions class. This option reduces memory consumption during the saving process, although it may increase the time taken to save the document.
Here’s how you can modify your code to enable memory optimization:
try:
document1 = aw.Document("自訂格式(電商匯入中心)11.pdf")
save_options = aw.saving.MarkdownSaveOptions()
save_options.image_resolution = 150
save_options.memory_optimization = True # Enable memory optimization
document1.save(f"自訂格式(電商匯入中心)11.md", save_options)
except Exception:
traceback.print_exc()
By setting save_options.memory_optimization to True, you can significantly decrease the memory footprint during the conversion process. However, keep in mind that this may result in slower performance when saving the document.
For more details on the MarkdownSaveOptions class and its properties, you can refer to the official documentation here and for memory optimization specifics, check this page.
If you continue to experience issues, consider checking the size and complexity of the PDF document you are converting, as these factors can also impact memory usage.

@David_Matin Could you please describe the environment where the problem occurs? We will check the issue on our side and provide you more information.
@David_Matin Thank you for additional information. Unfortunately, I cannot reproduce the problem on my side using the following simple code and Dockerfile:
doc = aw.Document("/temp/in.docx")
doc.save("/temp/out.pdf")
FROM ubuntu:20.04
ENV DEBIAN_FRONTEND=noninteractive
RUN apt update
RUN apt install -y python3.8 python3-pip
RUN apt install -y pkg-config libicu-dev
RUN python3.8 -m pip install aspose-words
# Copy function code
COPY app.py ./
ENTRYPOINT ["python3.8", "app.py"]
@alexey.noskov Did you use my document? I am saving the pdf in markdown format.
https://drive.google.com/file/d/1tVqPTe_CE0-GNuGS5sh-9ErIRm_586RZ/view?usp=sharing
code:
document = aw.Document(source_file)
save_options = aw.saving.MarkdownSaveOptions()
save_options.image_resolution = 300
document.save(f"{result}.md", save_options)
@David_Matin I have tested with your input document and still the problem is not reproducible on my side. The provided PDF document is successfully converted to Markdown.
@alexey.noskov Does this have anything to do with parsing the file after I split it? I first use aspose-pdf(24.3.0) to split the pdf file into a number of pdf according to the page number, and then these pdf conversion md
@David_Matin Could you please attach the PDF document that is passed to Aspose.Words and causes the problem? We will test with it and let you know the result.

@David_Matin Thank you for additional information. unfortunately, the problem is still not reproducible on my side. Please try with the docker file provided above and let us know if the problem is reproducible on your side.
@alexey.noskov Our Linux version is CentOS Linux release 7.9.2009 (Core).I reproduced the problem on this version of the machine.Same code and file,same error message.
@David_Matin I tested with CentOS and still the problem is not reproducible on my side.
Dockerfile:
FROM centos/python-38-centos7
USER root
# Install ICU package.
RUN yum -y install icu
WORKDIR /usr/app/src
# Copy function code
COPY app.py ./
RUN pip install aspose-words
ENTRYPOINT [ "python3", "app.py"]
app.py:
doc = aw.Document("/temp/in.pdf")
save_options = aw.saving.MarkdownSaveOptions()
save_options.image_resolution = 300
doc.save("/temp/out.md", save_options)
this time I used in linux server not in k8s
