Usage Examples:

IMAGINGNET-4746 [Aspose.Imaging] Resize a binary Tiff image with ResizeType.LeftTopToLeftTop and the background becomes black

string baseFolder = @"D:\";
string inputFileName = Path.Combine(baseFolder, "OrgA5.jpg");
string outputFileName = Path.Combine(baseFolder, "resized.jpg");
using (Image image = Image.Load(inputFileName))
{
     image.BackgroundColor = Color.Yellow;
     image.Resize(image.Width * 2, image.Height * 2, ResizeType.LeftTopToLeftTop);
     image.Save(outputFileName);
}

IMAGINGNET-4691 Fix bugs in a figures fill color

var baseFolder = @"D:\";
var fileName = "TestTransparent.cdr";
var inputFilePath = Path.Combine(baseFolder, fileName);
var outputFilePath = inputFilePath + ".png";
using (var image = (CdrImage)Image.Load(inputFilePath))
{
    image.Save(outputFilePath, new PngOptions
    {
        VectorRasterizationOptions = new CdrRasterizationOptions { Positioning = PositioningTypes.Relative }
    });
}

IMAGINGNET-4677 Fix bugs in CDR style reader for v14

var baseFolder = @"D:\";
var fileName = "7 Band Spectrum Acrylic Tower Version 2.cdr";
var inputFilePath = Path.Combine(baseFolder, fileName);
var outputFilePath = inputFilePath + ".png";
using (var image = (CdrImage) Image.Load(inputFilePath))
{
    image.Save(outputFilePath, new PngOptions
    {
        VectorRasterizationOptions = new CdrRasterizationOptions {Positioning = PositioningTypes.Relative}
     });
}

IMAGINGNET-4643 Exception when converting EMZ to JPG

string fileName = "image001.emz";
string baseFolder = @"D:\";
string inputFileName = Path.Combine(baseFolder, fileName);
string outputFileName = inputFileName + ".jpg";
using (var image = Image.Load(inputFileName))
{
    image.Save(outputFileName, new JpegOptions());
}

IMAGINGNET-4588 BUG - RasterImage.Filter GaussianFilterOptions Black pixel and border creation

string baseFolder = @"D:\";
string inputFileName = Path.Combine(baseFolder, "test_image.jpg");
string outFileName = Path.Combine(baseFolder, "result.jpg");
using (RasterImage image = (RasterImage)Image.Load(inputFileName))
{
     image.Filter(image.Bounds, new GaussianBlurFilterOptions(5, 5));
     image.Save(outFileName);
}

IMAGINGNET-4494 Property Image.Size for eps images is not optimized

var inputFilePath = "file_2.eps";
for (int i = 0; i < 100; i++)
{
	using (var image = Image.Load(inputFilePath))
	{
		var size = image.Size;
        Console.WriteLine(size);
	}
}

IMAGINGNET-4448 Support Image scoped fonts

/*
           This example demonstrates the custom font source providing to use the specific font(s) for image rendering.
           Unlike FontSettings.SetFontsFolders method works in the image scope and allowing to provide the fonts in multi-user scenarios.
