QUESTION
Is it possible in Django to save a pdf from a view to a model (while downloading it at the same time)?
So far, these steps work already:
- the pdf is displayed in a new tab and I can download it
- the model instance is created (but empty)
What dows not work:
- the created model instances does not have a file path and there is no PDF file saved anywhere on the server
My code:

Answered 2022-Feb-17 at 22:36The problem is that you are setting the fill color to that bluish gray when you draw the background, and leaving it there. The "fill color" is what is used to draw strings, so your text IS being drawn, it's just being drawn in your background color.

- completly removing my virtual environment

the --no-cache-dir

QUESTION
I am trying to put together a script to fix PDFs a large number of PDFs that have been exported from Autocad via their DWG2PDF print driver.
When using this driver all SHX fonts are rendered as shape data instead of text data, they do however have a comment inserted into the PDF at the expected location with the expected text.
So far in my script I have got it to run through the PDF and insert hidden text on top of each section, with the text squashed to the size of the comment, this gets me 90% of the way and gives me a document that is searchable.
Unfortunately the sizing of the comment regions is relatively course (integer based) which makes it difficult to accurately determine the orientation of short text, and results in uneven sized boxes around text.
What I would like to be able to do is parse through the shape data in the PDF, collect anything within the bounds of the comment, and then determine a smaller and more accurate bounding box. However all the information I can find is by people trying to parse through text data, and I haven't been able to find anything at all in terms of shape data.
The below image is an example of the raw text in the PDF, the second image shows the comment bounding box in blue, with the red text being what I am setting to hidden to make the document searchable, and copy/paste able. I can get things a little better by shrinking the box by a fixed margin, but with small text items the low resolution of the comment box coordinate data messes things up.
To get this far I am using a combination of PyPDF2 and reportlab, but am open to moving to different libraries.
...ANSWER
Answered 2022-Feb-03 at 07:44I didn't end up finding a solution with PyPDF2, I was able to find an easy way to iterate over shape data in pdfminer.six, but then couldn't find a nice way in pdfminer to extract annotation data.
As such I am using one library to get the annotations, one to look at the shape data, and last of all a third library to add the hidden text on the new pdf. It runs pretty slowly as sheet complexity increases but is giving me good enough results, see image below where the rough green borders as found in the annotations are shrunk to the blue borders surrounding the text. Of course I don't draw the boundaries, and use invisible text for the actual program output, giving pretty good selectable/searchable text.
If anyone is interested in looping over the shape data in PDFs the below snippet should get you started.

Install reportlab
You can use reportlab like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
