PDF to Image/SVG in Golang

[waTR]

We are building a set of RESTful services, which all are based on taking a PDF and transforming it into an image. Is there any code out there showing an example of what mix of libraries to use to do this. It would be a set of blue prints in PDF that would need to be converted to a high resolution image or SVG. The blueprints consist of lines and text only.

This library https://github.com/yob/pdfreader has some support for exporting to PDF.

It doesn't seem to be maintained but I am doing some work on it here https://github.com/raff/pdfreader.

Not sure of how good the SVG support is and I am not working specifically on that, but you can give it a try and possibly submit issues and/or pull requests.

GraphicsMagick?

ImageMagick is looking like the way to go. However, there is also this: https://github.com/yob/pdfreader

Ghostscript is the way to go on this: is the fastest I know, and I've used it. All others are using ghostscript AFAIK.

Here is an article/tutorial for how to do this with ImageMagick: https://golangcode.com/convert-pdf-to-jpg/

Here is some example code that converts PDFs (all pages) to JPG, and uploads to s3 for good measure!  Brilliant !
