Subject: Images in Jupyter Notebook to Markdown conversion
Date: Mon, 27 Dec 2021 02:36:52 -0800 (PST) [thread overview]
Message-ID: <6d84aa5d-bdc8-4612-b471-c7b270f3936an@googlegroups.com> (raw)

Hello everyone,
When i convert the images.ipynb notebook to markdown, the resuting document
contains
::: {.output .execute_result execution_count="4"}
![](fcbe61351f965c3664d65d5e93991915402e0483.png)
:::
but AFAICT, the png file is not generated. Using the standalone option does
not change anything. And of course, the round-tripping (md -> ipynb) fails
with:
File fcbe61351f965c3664d65d5e93991915402e0483.png not found in resource path
The original notebook can be visualized here:
https://github.com/boisgera/python-advanced-eval/blob/master/samples/images.ipynb.
The (Grace Hopper) image it contains is an image/png cell output
(Matplotlib is used to display the image) :
{
"cell_type": "code",
"execution_count": 4,
"metadata": {},
"outputs": [
{
"data": {
"image/png":
"iVBORw0KGgoAAAANSUhEUgAAAgAAAAJYCAIAAACbx8k3AAEAAElEQVR4nGT92dMsWZIfhrn72SIil2+/S9Xtqq7qbboxPSswwGAAGQwkRYEyQgYZARIvMiNIo0wveseDTGaCXkTqX+CLKJO4CRIIgaSGAIfAAAPMYLqnZ+nprurat7t+Wy4RcTZ3PXhGVPYgH67lzS8z4sRZfPn5z93x6tG/7X3jXUA0tWApAgAGbd/vlst
...
I am using pandoc 2.16.2 (Linux). Is it considered a bug or am I missing
something? Shall I file an issue?
Regards,
Sébastien
