How to view a GRF file

I have a txt file which is an impression of ZPL, but I can't pre-view that file. When opening the txt it has the following markup:
~DGR:DEMO.GRF,124236,102,:Z64:
What tool or code can I use to view this file?

The compression used for the GRF file is base64, so if you copy here all the stuff after the "Z64:" , you should be able to see the image.

How to add new text file in zip file using ruby

Is it possible to add a new text file in the zip file without extracting the zip file using ruby?

How to add a file to a .gz archive and delete the original file?

My files name is <09/12/2020>_master. How would I be able to add this file to a .gz archive and then remove the original file?

GZip isn't an archive format, it's a compression format. A .gz file can only contain one compressed file; if you need to put more than one file in at a time, you'll need to pair it with an archive format (such as tar).

Pandoc convert docx to markdown with embedded images

When converting .docx file to markdown, the embedded image is not extracted from the docx archive, yet the output contains ![](media/image1.png){width="6.291666666666667in"
height="3.1083333333333334in"}
Is there a parameter that needs to be set in order to get the embedded pictures extracted?

pandoc --extract-media ./myMediaFolder input.docx -o output.md
From the manual:
--extract-media=DIR Extract images and other media contained in or linked from the source document to the path DIR, creating it if necessary, and adjust the images references in the document so they point to the extracted files. Media are downloaded, read from the file system, or extracted from a binary container (e.g. docx), as needed. The original file paths are used if they are relative paths not containing ... Otherwise filenames are constructed from the SHA1 hash of the contents.

Referring to the comment by gridtrak and the problem of an unnecessarily deep directory strucutre (e.g. media/media/image2.jpeg), use the current directory as path DIR, then a folder media is created within the current directory (e.g. media/image2.jpeg):
pandoc --extract-media=. input.docx -o output.md
