Easy.Tools.ThumbnailMaker

Easy.Tools.ThumbnailMaker is a lightweight and flexible .NET library that enables quick and easy creation of thumbnails (small preview images), resizing images, and adding text watermarks in your applications.

Features

  • Asynchronous image loading and thumbnail generation
  • Automatic EXIF orientation correction (auto-orient)
  • Flexible resize modes: Fit, Cover, Pad, Crop, Contain
  • Background color and padding support
  • Text watermark with customizable position, font, color, size, and opacity
  • JPEG and PNG output formats
  • Metadata stripping options (EXIF, ICC, XMP profiles)
  • Minimal external dependencies, high performance
  • Cross‑platform (Windows, Linux, macOS)

Installation

Install via NuGet:

dotnet add package Easy.Tools.ThumbnailMaker

Usage

Simple thumbnail creation

using ThumbnailMakers;

// Input and output file paths
await using var input = File.OpenRead("test.jpeg");
await using var output = File.Create("test1.jpeg");

// Define thumbnail colors
var white = ThumbnailColor.White;
var red = new ThumbnailColor(255, 0, 0);
var semiTransparentBlue = new ThumbnailColor(0, 0, 255, 128);
var fromHex1 = ThumbnailColor.FromHex("#FF0000");        // RRGGBB
var fromHex2 = ThumbnailColor.FromHex("80FF0000");       // AARRGGBB

// Create a thumbnail with specific options
var opts = new ThumbnailOptions(320, 320)
{
    Mode = ThumbnailResizeMode.Cover,
    Output = OutputFormat.Jpeg(85),
    Watermark = Watermark.TextMark("© ACME", size: 18, opacity: 100f, color: red)

};

// Create the thumbnail
await Thumbnail.MakeAsync(input, output, opts);
