gg VS canvas

The author explicitly says:

> You don't need to download any dependencies such as plantUML or Graphviz, which is what most of the tools out there require and what was also my motivation to start this project. go-uml is using a 2D graphics engine written 100% in Go https://github.com/fogleman/gg

So no, this is not a solution for these requirements.

I really like the [fogleman/gg](https://github.com/fogleman/gg) package for image manipulation, it is pure Go and has many functions to draw and manipulate images.

you can try something like: https://github.com/fogleman/gg to create such images from templates

I've always used the GG library for my image processing needs, and I've heard of libvips somewhere before (likely from the Node.js world) but didn't know it had a Go port/wrapper. :) I'll definitely check that out as well

what library are you using? I recommend this one.

Mainly, the standard library and my favorite gg.

Have you been hit by https://github.com/fogleman/gg/issues/85 when writing your book?

It does relatively little, and that's the point! It works really well when you combine it with other packages; I find it plays very well with fogleman/gg, but your objectives may differ. The dev is very responsive and helpful (even if I don't understand their tweets).

That piece of code makes all the magic. With the help of Fogleman library manipulating images in Go is a breeze. Let's check what this is doing:

The base image package doesn't have text rendering functions. It would probably be easier to use a higher level library like https://github.com/fogleman/gg

I wanted to share a recent large update to https://github.com/tdewolff/canvas, which is a vector graphics library written in Go to create images, PDFs, SVGs, OpenGL, etc. using vector drawing operations. Especially I wanted to show two new exciting features:

It appears that there's a port of Cairo to Go which also targets webassembly. https://github.com/tdewolff/canvas

https://github.com/tdewolff/canvas/blob/master/examples/opengl/main.go can draw primitves but i think it would be a bit hard to do event based animation

Yes! See https://github.com/tdewolff/canvas/tree/master/examples/gonum-plot for an example using gonum-plot. You should be able to plug-and-play to use the canvas library!
