100 is simply 'fatal error' ie something really bad happened. More information is generally printed to stdout or stderr, of course setting -dQUIET will suppress much of this. Since you are getting -100 returned its almost certainly the case that your arguments to Ghostscript are incorrect in some way. The absolute first thing you should do when debugging problems is to try and simplify the problem, so remove any switches that you don't unquestionably require. So the first thing to do is to remove the -dQUIET, capture all the stdout/stderr output and tell us what it says. Spartacus gods of the arena season 1 episode 2 full.

Further to that, note the following: You don't need '-f' because the only purpose of that switch is to terminate -c which you haven't used. You haven't given the values of 'resolucao', 'pageNumber', or 'pdfPath' or so there's no way to know if those are valid (or sensible). The path you have specified for outputImgPath is quite long, and includes the backslash character.

Syncfusion Essential PDF is a.NET PDF library used to create, read, and edit PDF documents. Using this library, you can convert PDF to JPG in C# and VB.NET. Steps to convert PDF to JPG programmatically: Create a new C# console application project.

I would advise using the forward slash '/' instead, as backslash is used to begin an escape and can give results you may not expect. You've also used -dSAFER, do you understand the implications of specifying this? If not, remove it and try again. When you have created the string 'args' print it out.

At the very least this will give you something you can try from the command line, and may mean that other people have some chance of reproducing your problem. Finally; please note that Ghostscript is distributed under the Affero General Public Licence, please be sure to read the licence and ensure that you are conforming to the terms contained therein. Thank you to answer, @kens. The pdfPath is a digitally signed PDF with multiples pages, so, pageNumber varying between 1 and last page of this pdf. I remove -f, -dQUIET, -dSAFER, -r, -dTextAlphaBits, -dGraphicsAlphaBits, -dFirstPage and -dLastPage to debugging this code. Doing this, the command line is: gswin32c -dNOPAUSE -dBATCH -sDEVICE=png16m -sOutputFile=C:/Download/DocumentosV2/Protocolo/Pronunciamento/fb21872746b64f8fb31b3764b5444e2e.png C: Upload DocumentosV2 Protocolo Pronunciamento 3_0_4047_10081288_230_0_f1f09b4b38ac49a8a3e5576f6041eea3.pdf.

In essence it is so that, if your application is released under GPL or is not for commercial distribution you could use ghostview and for instance include the ghostview installation routine with your application (You should verify this by reading the licenses carefully). If your application, is commercial and closed source or uses a open source license that is not compatible with GPL, you would have to buy a license. If that is the case, I would recomend you to look at all the commercial alternatives as other solutions than ghostview can be easier to use / better depending on your scenario.
