Harness the power of this functionality with ease by following the C# example provided below:

var baseFolder = "D:\\";
FontSettings.SetFontsFolder(Path.Combine(baseFolder, "Fonts"));
using (var image = Image.Load(Path.Combine(baseFolder, "Test.cdr")))
    image.Save(Path.Combine(baseFolder, "Test.cdr.jpg"));

For additional information, please refer to the Aspose.Imaging 23.11 release notes.

Aspose.Imaging for .NET 23.10

         With the release of Aspose.Imaging 23.10, significant changes have been implemented to enhance the interface and behavior of the `EpsImage` class for EPS file manipulation. Here's a summary of the key points:

  • EpsType Enumeration: Utilize the EpsImage.EpsType property to retrieve the file sub-type, as the EpsInterchangeImage and EpsBinaryImage classes have been deprecated.

  • Preview Image Retrieval: To obtain a specific preview image or a list of all preview images, utilize the EpsImage.GetPreviewImage(EpsPreviewFormat) method or access the EpsImage.PreviewImages property. This replaces the usage of EpsLoadOptions.PreviewExportFormat and EpsRasterizationOptions.PreviewToExport properties, which have been removed.

  • EPS File Export: Export EPS file renders using the EpsImage.Save(Stream, ImageOptionsBase) method. The EpsPreviewFormat.PostScriptRendering property is no longer available.

This filter provides a convenient solution for users who need to share photos without these unwanted marks, enhancing the overall quality and presentation of their images.

         Here's a simple example of how you can use the `WatermarkRemover` class in C# for watermark removal:

var imageFilePath = "ball.png";
var outputFilePath = "result.png";
using (var image = Image.Load(imageFilePath))
    var pngImage = (PngImage)image;

    var mask = new GraphicsPath();
    var firstFigure = new Figure();
    firstFigure.AddShape(new EllipseShape(new RectangleF(350, 170, 570 - 350, 400 - 170)));

    var options = new ContentAwareFillWatermarkOptions(mask)
        MaxPaintingAttempts = 4

    var result = WatermarkRemover.PaintOver(pngImage, options);

    result .Save(outputFilePath);

The tool automatically extends the selection to include all adjacent areas sharing a similar color, streamlining complex selections and adjustments.

C# code example:

using (RasterImage image = (RasterImage)Image.Load("src.png"))
    // Create a new mask using magic wand tool based on tone and color of pixel {845, 128}
    MagicWandTool.Select(image, new MagicWandSettings(845, 128))
        // Union the existing mask with the specified one created by magic wand tool
        .Union(new MagicWandSettings(416, 387))
        // Invert the existing mask
        // Subtract the specified mask created by magic wand tool from the existing one
        .Subtract(new MagicWandSettings(1482, 346) { Threshold = 69 })
        // Subtract four specified rectangle masks from the existing mask one by one
        .Subtract(new RectangleMask(0, 0, 800, 150))
        .Subtract(new RectangleMask(0, 380, 600, 220))
        .Subtract(new RectangleMask(930, 520, 110, 40))
        .Subtract(new RectangleMask(1370, 400, 120, 200))
        // Feather mask with specified settings
        .GetFeathered(new FeatheringSettings() { Size = 3 })
        // Apply mask to the image

         For a comprehensive explanation accompanied by images and additional information, please consult our Developer Guide article "Magic Wand tool".

By overlaying a semi-transparent logo onto the original document, the author's ownership is established discreetly yet prominently. The provided C# code example demonstrates the application of this technique, utilizing the Blend() method from the `RasterImage` class. This method seamlessly combines two images, background and overlay, enabling the efficient creation of visually engaging compositions, including watermarks, with ease.

using var background = Image.Load("background.webp") as RasterImage;
using var overlay = Image.Load("logo.png") as RasterImage;

var center = new Point((background.Width - overlay.Width) / 2, (background.Height - overlay.Height) / 2);
background.Blend(center, overlay, overlay.Bounds, 127);


         Please explore our Developers Guide article "Alpha Blending Image Filter" for more detailed explanations accompanied by image examples.
