pdftoimage | A ruby gem for converting pdfs to images | Document Editor library

According to the rmagick docs, imagelist does not support urls for converting images. You need to use open-uri gem and URI.open method to open the PDF and pass it to the imagelist.

If your objective is to make uso of Ghostscript .NET directly, you would not need to reference the original Ghostscript DLL from your project (as I said, until you desire to do so).

I tested Ghostscript .NET over Windows 7 and windows 10, with Visual Studio Community 2017 simply following these steps:

1. Install Ghostscript 9.52 for Windows (32 bits).

2. Using Nuget package manager, added Ghostscript .NET to my solution.

3. Include using code lines, as required (main namespace and Rasterizer for your case should work, I use Processor, in addition):

I got it: Stop WPF ScrollViewer automatically scrolling to perceived content got me in the right direction. I simply had to set

Well, the current version of Ghostscript (9.25) renders this acceptably for me; that is the text appears to be correct. All the fonts are embedded, so there shouldn't be any problems.

And this means that even if you did replace the default font substitution, it wouldn't help, because Ghostscript shouldn't be using the default font, it will be using the fonts embedded in the PDF file.

Without knowing what version of Ghostscript you are using (I see from a later comment that its 9.25), or the command line that is used to start it, I can't really do a like-for-like comparison. Its hard for me to see how you could be getting such a different result though. That looks like Ghostscript has failed to find the embedded fonts.

Its possible that whatever package you are using has done something 'unfortunate'. The various package maintainers on Linux add their own patches, and sometimes modify the way that Ghostscript is built. Possibly that has broken something.

If you are able to build Ghostscript yourself you could try cloning our Git repository and doing that. You could also try downloading the Linux binaries off our website. They won't work with every Linux distribution (different ABI) but you can try, you might be lucky.

You could also try running Ghostscript directly on the PDF file. Something like:

gs -sDEVICE=png16m -o out%d.png

should produce 2 PNG files, out1.png and out2.png. It will also produce a bunch of stuff on the terminal. That back channel output is valuable information for me so if you can reproduce the problem, I'd like to see that too.

One last thought; its possible to have more than one version of Ghostscript installed simultaneously, its possible that your current setup is using an old version of Ghostscript.

I can't help you with ImageMagick or Spatie, but if you can debug those to the point where you can reproduce the problem with a plain Ghostscript command line then I can look further at it.

You do not need a lib for this, imagick alone will do fine.

Working example

Function.json:

Well, Ghostscript is telling you it can't open the file '/config:C:\Users\Sean.McNary\ApexRemington\.vs\config\applicationhosts.config' because (not entirely unsurprisingly with such a garbled filename), it can't find the file.

I presume you are using some kind of wrapper around Ghostscript (which is a DLL written in C), because you are apparently using C#, it would help if you were to state what you are using there.

It 'looks like' whatever wrapper you are using, it expects to be given an input filename, and simply passes that to Ghostscript. While it is possible to pass data from memory to Ghostscript, and to have the rendered result returned in memory, you should be aware that if the input is a PDF file you aren't saving anything, because Ghostscript will spool the whole input to a temporary file before processing it You have to seek around a PDF file, so you need to have random access, hence its written out as a file.

You are going to have to debug into your wrapper and see what its doing.
