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:
```d
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.
