New Feature - Remove and Change Background for Vector Images

         Aspose.Imaging for .NET now offers robust background removal capabilities not only for raster images but also for vector formats like SVG, EMF, and CDR. Unlike raster images, background removal in vector files involves identifying and isolating objects without underlying shapes considered part of the background. The library allows you to specify a background color for removal, excluding foreground elements of the same color. Additionally, targeted background removal within specific areas of the image is possible. Removed backgrounds with the RemoveBackground() method of `VectorImage` class, can be replaced with a new color or saved as foreground shapes on a transparent layer, providing flexibility and precision in image editing. To access C# code snippets and image examples illustrating background removal before and after, please refer to our Developer Guide article "Remove background from vector images in C#". It contains detailed demonstrations that will guide you through the process effectively.

Upgrade today and increase efficiency in your image processing workflows. You can find additional insights and explanations in the Aspose.Imaging 23.12 release notes.

Seamlessly incorporate fonts with these styles into your designs by simply adding a font folder using the `FontSettings.SetFontsFolder()` method. 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.

These changes streamline EPS file manipulation, providing a more intuitive and efficient workflow. Upgrade to Imaging 23.10 to leverage these enhancements and optimize your EPS file handling processes.

New Feature - Remove watermark filter

         A new feature called the Remove Watermark Image Filter managed through the WatermarkRemover class, enables users to remove unwanted watermarks, such as manufacturer logos or device model names, from photos captured by certain smartphones and cameras. 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)));
    mask.AddFigure(firstFigure);

    var options = new ContentAwareFillWatermarkOptions(mask)
    {
        MaxPaintingAttempts = 4
    };

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

    result .Save(outputFilePath);
}

New Feature - Magic Wand tool

         The Magic Wand tool is indispensable for graphic designers, allowing easy selection of specific color areas in images or photos. By utilizing the MagicWandTool class from the Aspose.Imaging library, designers can select a color area by simply choosing a point within it. 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
        .Invert()
        // 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
        .Apply();
    image.Save("output.png");
}

         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);

background.Save("blended.webp");

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