QUESTION
I have a NodeJS API and I need to create an endpoint which creates a richly-featured dynamic PDF report and saves it to an S3 bucket. I've been working with PDFKit (https://pdfkit.org/) and have most of what I need from there, but I've come up across a stumbling block because the latest design I've been given includes a donut chart generated with eCharts and I can't figure out how to include this using PDFKit. It needs to be generated dynamically for each call. There is no visible HTML page which displays the report, this must all be achieved within the NodeJS API.
Are there any pre-existing solutions I'm overlooking that would make this possible?
NB I have some flexibility so it doesn't have to be specifically an eCharts solution, as long as I can include a stacked donut chart with labels.
Thanks.

Answered 2021-Jun-10 at 13:53This is totally doable. I've put together an example that adds a chart to the PDFKit document.

I would like to generate invoices with a little Python program I've written. I want it to output the invoice first as an HTML file, then convert it to a PDF. Currently my code is creating the HTML doc as desired, but it is outputting a blank PDF file:

Answered 2021-Jun-06 at 15:59You never close the file you're writing to, or explicitly flush it. Since it's a small text snippet, and buffering is enabled by default, it doesn't get written to disk until after your process terminates. You don't see an error because the file does get created immediately as it's opened though. The issue is not one of timing as you seem to suppose.
There are any number of solutions to this problem. The simplest and most correct is to close the file as soon as you're finished writing to it. This is how you open a file idiomatically in python:

I am downloading the signed documents using the docusign getDocument API, but the downloaded file is coming in a weird format(json as per the Content-type header). What format is this and how can I convert it to a viewable/readable format.

...ANSWER
Answered 2021-May-10 at 23:21What language are you using, and are you using one of the DocuSign SDKs or a raw API call?
When I make a GetDocument call (specifically {{vx}}/accounts/{{accountid}}/envelopes/{{envelopeId}}/documents/combined
, for example), the response headers have Content-Type: application/pdf
and Content-Dispostion: file; filename=file.pdf
, and the body of the response is the binary of the PDF file itself.

Looking for some direction
I'm working with PDFKit. Everything is going fine but having trouble finding the methods (documentation / WWDC / elsewhere ) on how to stop text from drawing at a certain y position and start the next page. Any saved references or a snippet of code would be a great help.

Answered 2021-May-06 at 06:35I dont know, wether this is the best way to implement your use case, but it worked for me. When adding a new line into the PDF_Context, I recalculate a variable the keeps tracking of the current content height of my PDF_Page. When it exceeds a certain value, I create a NEW page, set the content height to zero and go on filling, ...

I have a code in Python Flask where I generate pdf files using an HTML template. The code works just fine when I run it alone, but when I try to run it inside a Docker container, as soon as I call the endpoint that generates the report the docker crashes and resets. It just stays loading then it returns an error (in Postman which I'm using to test).
The code for the PDF is as follows:

I'm trying to use pdfkit v.0.12.1 with AWS CDK and a Lambda function (tried both typescript and js). When I try to run it I get this error:
Error: ENOENT: no such file or directory, open '/var/task/data.trie The Lambda looks like this:
...ANSWER
Answered 2021-Apr-28 at 17:09pdfkit was not loaded properly in the lambda function. I solved this by following this advice for adding external dependencies to a lambda function in CDK.
Basically, create a separate folder for your lambda in your CDK set up with a seperate node modules folder. On deploy, all of this will be packed together to have the dependencies available.
After that, pdfkit works as expected.
QUESTION
My app does PDF creation. As part of it, I have successfully allowed the user to add an image, and the image is cropped to a circle and added. When you view the subsequently created PDF on the screen, or on a computer screen, it looks great. But when you print it off, it prints part of that transparent background off, as seen in the images versus how it looks on screen. Is this a problem with PDFKit within Xcode or is there something I can be doing to fix this?

Answered 2021-Apr-13 at 14:10Couple things...
- Is there a reason you are converting to
CGImage
and back? - Are you sure the background is completely transparent?
- If you're sure, then you may want to try using a clipping path.
Here's the result of my quick test...
