Dealing with large files that have a lot of images?

Questions
1

I am working on a document that has an auto-generated appendix that contains a large number of large images. There are about 420 images and I have compressed these images down to about 1 MB each. Trying to include all of the images gives me a “memory allocation failed” message. I have tried reducing the number of images to experiment and I have some success, depending on what images I cut out, I can compile a document with anywhere between 50 and 200 images included (The maximum number of images appears unrelated to file size).

Is there any method or trick I can use to deal with this issue? Would it be best to just incrementally compile the document and stitch it together after the fact?

Thanks!

Except dividing the whole file into small parts in source code level, there are many ways:

  • typst compile xxx.typ --pages 1-90
  • typst compile xxx.typ -j 1
  • buy bigger memory cards
3 
typst compile xxx.typ --jobs 1

This is a valid command but it’s also not documented with typst --help. What is it supposed to accomplish?

From typst-compile(1) — Arch manual pages

-j, --jobs=JOBS
Number of parallel jobs spawned during compilation. Defaults to number of CPUs. Setting it to 1 disables parallelism

So I don’t think it does really help with this problem.

You could use -h on sub-commands too.

typst -h
typst c -h
typst c -j -h

I do not test a benchmark or profile to analyze memory usage, but multiple process instance run simultaneously will use more memory at first glance.

@scdyer Apart from real memory card hardware, u can also set virtual memory in a software way, that will use disk as memory.

Aha I see this parameter is documented under typst compile help.

You mean increase the amount of virtual memory available by increasing the size of the available swap(file).
