Magick.NET

Magick.NET wraps ImageMagick for .NET (Windows, Linux and macOS, x64 and arm64). It reads palette, grayscale and true-color TGA files, raw and RLE, and writes TGA with or without RLE. The same API handles 100+ other formats, so it’s a good choice for conversion services.

The package comes in Q8 (8 bits per channel) and Q16 (16 bits per channel) builds. TGA is 8 bits per channel, so the smaller and faster Q8 build is enough unless you also process high bit depth formats.

Installation#

dotnet add package Magick.NET-Q8-AnyCPU

Basic usage: convert TGA to PNG#

using ImageMagick;

using var image = new MagickImage("in.tga");
Console.WriteLine($"{image.Width} x {image.Height}, alpha: {image.HasAlpha}");
image.Write("out.png");  // format from the extension

How to save a TGA with RLE compression#

using ImageMagick;

using var image = new MagickImage("in.png");
image.Settings.Compression = CompressionMethod.RLE;  // CompressionMethod.NoCompression for raw
image.Write("out.tga", MagickFormat.Tga);

How to get TGA width and height without decoding#

using ImageMagick;

var info = new MagickImageInfo("in.tga");
Console.WriteLine($"{info.Width} x {info.Height}, {info.Format}");

How to read a TGA from a stream or a file without the .tga extension#

TGA has no magic bytes, so tell Magick.NET the format:

using ImageMagick;

var settings = new MagickReadSettings { Format = MagickFormat.Tga };
using var stream = File.OpenRead("texture.bin");
using var image = new MagickImage(stream, settings);

How to write TGA to a byte array#

using var image = new MagickImage("in.png");
byte[] tga = image.ToByteArray(MagickFormat.Tga);

Tips#

• Width and Height are uint in current versions.
• Strip metadata you don’t need with image.Strip() before writing.
