I have created a small .net core 3.1 console application to convert pdf to png using Magick.Net (https://www.nuget.org/packages/Magick.NET-Q16-AnyCPU/). I have also installed ghostscript public license. It's doing alright but the output image is totally black and I can't read a single line. If I open the file using Paint then it's fine. Here is my code:
public static int ConvertFileToImages(string filePath, string destinationPath)
{
int noofPages = 0;
MagickReadSettings magickReadSettings = new MagickReadSettings();
magickReadSettings.Density = new Density(300, 300);
using (MagickImageCollection magickImageCollection = new MagickImageCollection())
{
magickImageCollection.Read(filePath, magickReadSettings);
int page = 1;
noofPages = magickImageCollection.Count;
foreach (MagickImage magickImage in magickImageCollection)
{
magickImage.Format = MagickFormat.Png;
magickImage.BackgroundColor = MagickColors.White;
string imageFilePath = string.Concat(destinationPath, "file-", page, ".png");
magickImage.Write(imageFilePath);
page++;
}
}
return noofPages;
}
Am I doing anything wrong?
