using (var image = Image.Load("CompressedTiger.bmp"))
{
    image.Save("DecompressedTiger.bmp", new BmpOptions());
}

IMAGINGNET-4800 Convert SVG to PNG Problem

const string baseFolder = @"D:\";
const string fileName = "Halle_2.svg";
var inputFileName = Path.Combine(baseFolder, fileName);
var outFileName = inputFileName + ".png";
using (Image image = Image.Load(inputFileName))
{
   image.Save(outFileName, new PngOptions());
}

IMAGINGNET-4785 Regression in compression methods when exporting to PSD format

using (Image image = Image.Load("p2.png"))
{
    image.Save("output.psd", new PsdOptions() { CompressionMethod = CompressionMethod.RLE });
}

IMAGINGNET-4783 Unable to open the Tiff file

var testTiffImage = @"D:\00013562300662_C7N1_s103.tif";
var testTiffBytes = File.ReadAllBytes(testTiffImage);
using (var msSource = new MemoryStream(testTiffBytes))
using (var imgSource = Aspose.Imaging.Image.Load(msSource))
{
   imgSource.Save(@"D:\00013562300662_C7N1_s103.tif.png", new PngOptions());
}

string inputDirPath = @"C:\Data\input";
string outputDirPath = @"C:\Data\output";

// Repeat until error
for (int i = 0; i < 10; i++)
{
	ConvertFiles(inputDirPath, outputDirPath);

	// If no error, clear output files.

	{
		File.Delete(outputFile);
	}

	this.CurrentTestingMethodName = "TestMemoryLeaking";
	string inputFilePath = GetFileInCustomFolderRelativeToBase(filePath);
	WeakReference w = JustLoad(inputFilePath);
	System.Diagnostics.Stopwatch watcher = new System.Diagnostics.Stopwatch();
	watcher.Start();
	while (w.IsAlive)
	{
		if (watcher.ElapsedMilliseconds > 10000)
		{
			Assert.Fail("Image is still in memory!");
			return;
		}

		GC.Collect();
		System.Threading.Thread.Sleep(300);
