Magick.NET

Magick.NET reads an EPS file by calling Ghostscript, which renders the graphic at the Density you set; the image is cropped to the bounding box. The result is a normal MagickImage you can resize, convert or composite. Writing EPS works without Ghostscript but produces a raster image inside a PostScript wrapper, not vector art.

Installation#

dotnet add package Magick.NET-Q8-AnyCPU

Install Ghostscript (same bitness as your process), or copy its DLL next to your app and call MagickNET.SetGhostscriptDirectory(path).

Basic usage: convert EPS to PNG#

using ImageMagick;

var settings = new MagickReadSettings
{
    Density = new Density(300),  // dpi used to rasterize the vector art
};

using var image = new MagickImage("logo.eps", settings);
Console.WriteLine($"{image.Width} x {image.Height} px");
image.Write("logo.png");

How to convert EPS to a JPEG of a given width#

Render at a high density, then resize down for smooth edges:

var settings = new MagickReadSettings { Density = new Density(300) };
using var image = new MagickImage("logo.eps", settings);
image.BackgroundColor = MagickColors.White;
image.Alpha(AlphaAction.Remove);   // JPEG has no transparency
image.Resize(800, 0);              // 800 px wide, keep aspect ratio
image.Quality = 90;
image.Write("logo.jpg");

How to get the size of an EPS graphic#

Ping reads the header without rendering. At the default 72 dpi one pixel is one point:

using var image = new MagickImage();
image.Ping("logo.eps");
Console.WriteLine($"{image.Width} x {image.Height} pt");

How to save an image as EPS#

using var image = new MagickImage("photo.jpg");
image.Write("photo.eps", MagickFormat.Eps3);  // Level 3, compressed

MagickFormat.Ept writes EPS with a TIFF preview in the binary header, for programs that only show previews.

Tips#

• For EPS to PDF with vectors kept, use Ghostscript (pdfwrite) through Ghostscript.NET; Magick.NET would rasterize it.
• CMYK EPS files come out as CMYK images; set settings.ColorSpace = ColorSpace.sRGB before reading to get RGB.
