Usage Examples:

IMAGINGNET-7079 Resolve EPS rendering issues

EPS to PNG export exapmle:

var input = @"input.eps";
using var image = Image.Load(input, new LoadOptions { DataRecoveryMode = DataRecoveryMode.ConsistentRecover });
image.Save(input + ".png");

IMAGINGNET-7009 EPS to PNG export issue: NotImplementedException

EPS to PNG export exapmle:

using var image = Image.Load("image.eps");
image.Save("output.png");

IMAGINGNET-6992 Saving GIF results distorted output file

GIF saving example:

using var image = Image.Load("Input.gif");
image.Save("Output.gif");

IMAGINGNET-6892 Fix ArgumentNullException on Graphics.MeasureString

var path = @"arrow.png";
using (var image = Image.Load(path))
{
    var g = new Graphics(image);
    var size = g.MeasureString("Hello", new Font("Arial", 10), new SizeF(100, 100), StringFormat.GenericDefault);
    Console.WriteLine(size);
}

IMAGINGNET-6874 Looks like Aspose.Imaging.Image.GetFileFormat has lock inside

cpp
            InitWatermarker(smallFileName, false);

            InitSingleThread();

            Console.WriteLine("------------------");

            InitMultiThreads();

            Console.WriteLine("------------------");

            Console.WriteLine("All threads has completed.");


 cpp
  static string bigFileName = "D:\\15-MB-docx-file-download.docx";
  static string smallFileName = "D:\\source.docx";

  static void InitSingleThread()
  {
      InitWatermarker(bigFileName);
      InitWatermarker(smallFileName);
  }

  static void InitMultiThreads()
  {
      var t1 = new Thread(() =>
      {
          InitWatermarker(bigFileName);
      });

      var t2 = new Thread(() =>
      {
          InitWatermarker(smallFileName);
      });

      t1.Start();
      t2.Start();

      t1.Join();
      t2.Join();
  }

  static void InitWatermarker(string fileName, bool consoleOutput = true)
  {
      Stopwatch stopwatch = new Stopwatch();
      stopwatch.Start();

      using (FileStream stream = new FileStream(fileName, FileMode.Open, FileAccess.Read)
      {
          var fileFormat = Aspose.Imaging.Image.GetFileFormat(stream);
      }

      stopwatch.Stop();

      if (consoleOutput)
      {
          Console.WriteLine($"Init {fileName} take {stopwatch.ElapsedMilliseconds}ms");
      }
  }


Result:
 text
Init D:\15-MB-docx-file-download.docx take 18ms
Init D:\source.docx take 1ms
------------------
Init D:\source.docx take 8ms
Init D:\15-MB-docx-file-download.docx take 12ms
------------------

IMAGINGNET-6796 EmfPlus is not rendered correctly

cpp
 using (var image = Image.Load("D:\\test.emf"))
 {
     image.Save("D:\\test.png");
 }

IMAGINGNET-6725 Incorrect conversion the EPS image to SVG

EPS to SVG export example:

var inputPath = @"image.eps";
using var image = Image.Load(inputPath);
image.Save(inputPath + ".svg");

IMAGINGNET-6234 ESP to PNG: System.ApplicationException: Unknown name ’eexec’

EPS to PNG export exapmle:

using var image = Image.Load("image.eps");
image.Save("output.png");
