I built a simple worker to do some magic with images by using Go & VIPS . I chose VIPS because it is blazing fast compared to other Go image processing libraries. So this is the story about what went wrong.

Because my DEV setup is Apple MacBook Pro with M1 Apple Silicon, it’s always tricky to compile something to the proper architecture. Installing VIPS on my machine, it’s pretty straightforward:

brew install vips

You can find some online APIs and use the free tier to test them, but you can make them your own. So without any further instructions, here is a recipe.

Recently one of my clients contacted me asking if I could make a change. The task was to shrink huge margins on PDF delivery slips. The mission wasn’t easy because the settings were hidden in the files. You can change font size and amend or remove elements from the printout by modifying templates. Unfortunately, you can’t decrease the margin on PDF printouts.

Tesseract it’s a great library Open Source library to supply free OCR solutions for multiple libraries. You can use it directly from command line, or in your own software using supplied libraries.

Quite often we are looking for a quick way to make a request in GO, and we have working query tested in CURL. Sometimes it’s problematic to “move” all queries to GO, and build up whole query using client, protocol and so on.

From the author of my beloved Caddy server there is a tool called curl-to-Go which basically does what is says. Just paste your CURL request and GO lang code to implement that.
