When I need to convert a PDF image in console, I use ImageMagick: convert doc.pdf doc.png command. Today I found ImageMagick D bindings -- DMagick https://github.com/MikeWey/DMagick. I would like to script this operation using DMagick. However, I couldn't find any code samples and was not able to find anything about image conversion in official ImageMagick C API docs either (maybe I need to spend more time though). But maybe someone has code samples of how to convert PDF?

It's been awhile since i used it myself, but if imagemagick supports reading PDF's this might work:

```
Image pdf = new Image("./test.pdf")
pdf.write("./test.png")
```

DMagick hasn't been updated in a while so it will probably not work with newer versions of ImageMagick.

For his personal use you think there's any problem just using std.process?
I mean:

rdmd --eval='import std.process; auto dmd =  execute(["convert", `Screenshot from 2021-09-12 18-14-22.png` , `hello.pdf`]);'

I don't see why go beyond that if it's guaranteed that the user has convert on their machine

Yes, this is an option although I want to use it as a dub dependency as part of the project.
