How to save a LateX rendered image (via Latexify) to disk in png in Julia

I am using Julia.
I used Latexitfy to generate an image from a model equations using the following code:

Latexify.latexify(model_equations) |> render

Now I'd like to export that image generated to save it on my disk.
How can I do that ?

You can render to a target MIME type using the second argument to render. The documentation provides a useful example:

latexify(:(x/y)) |> s -> render(s, MIME("image/png"))

Breaking down this one-liner:

l = latexify(:(x/y))  # convert the fraction x/y to LaTeX text
m = MIME("image/png") # set up a MIME type target of PNG (can also be "image/svg")
render(l, m)          # save the rendered LaTeX to a temporary PNG and try to display it

The render function takes several keyword arguments that are not well documented. If you want to write the rendered LaTeX to a file with a specific name, pass the name argument. Note that the extension .png will be added automatically:

render(l, m, name="./my_file_name")

Note two things about the file name:

1. The name does not have a ".png" extension. The package will add the appropriate extension itself. It is also likely to create other files in the same directory that are byproducts of compiling a latex document, like my_file_name.tex, my_file_name.aux, my_file_name.log, and my_file_name.pdf.
2. The name includes a directory. Because of a bug in the package that was fixed shortly after this post, if you did not include a directory name in the file name, the method would throw ERROR: IOError: cd(""): no such file or directory (ENOENT). This has been fixed as of Latexify v0.15.19.

The method call with the name argument will still attempt to display the image. If you do not want the image to be displayed, pass false to the open argument:

render(l, m, name="./my_file_name", open=false)
