TargaSharp

CI

A .NET library for reading, editing and writing Truevision TGA (.tga) image files, covering the full TGA 2.0 specification: header, color map, raw and run-length-encoded image data, developer area, extension area (scan-line table, postage stamp, color-correction table) and footer.

Derived from TGASharpLib by Alex Green.

Packages

Package Targets Purpose
TargaSharp net48, net6.0, net8.0, net10.0 Core: file model, reader, writer, validation. No native or OS-specific dependencies.
TargaSharp.Drawing net48, net6.0, net8.0, net10.0 (Windows) System.Drawing.Bitmap ↔ TgaFile conversion via GDI+. 
dotnet add package TargaSharp
dotnet add package TargaSharp.Drawing   # optional, Windows only

Usage

Read, edit, write

using TargaSharp;

var tga = new TgaFile("input.tga");          // or new TgaFile(byte[]) / new TgaFile(Stream)

ushort width  = tga.Width;
byte[] pixels = tga.ImageArea.ImageData;      // decoded, BGR(A) byte order, row-major
var origin    = tga.Header.ImageSpec.ImageDescriptor.ImageOrigin;

tga.ExtensionArea!.AuthorName = new TgaString("me", 41, true);
tga.Flip(vertical: true);                     // toggles the origin bit; pixel data is untouched
tga.ToOldFormat();                            // drop footer/extension/developer areas -> plain TGA 1.0; ToNewFormat() is the inverse

tga.Save("output.tga");                       // or tga.Save(Stream) / byte[] bytes = tga.ToBytes()

Create from scratch

var tga = new TgaFile(256, 256, TgaPixelDepth.Bpp32, TgaImageType.RleTrueColor, attrBits: 8);
FillPixels(tga.ImageArea.ImageData);          // 256 * 256 * 4 bytes, B G R A per pixel
tga.Save("new.tga");

Validate before writing

foreach (TgaValidationError e in tga.Validate())
    Console.WriteLine($"{e.Path}: {e.Message}");

Save/ToBytes run the same validation and throw TgaValidationException (with the full error list) rather than writing an inconsistent file. Reading is lenient: files with out-of-spec metadata still load; only malformed structure raises TgaFormatException.

Reader / writer interfaces

using TargaSharp.IO;

ITgaReader reader = new TgaReader();
TgaFile tga = reader.Read(stream);

ITgaWriter writer = new TgaWriter(new TgaValidator());   // validator is injectable
writer.Write(tga, stream);                               // any writable stream, seeking not required

Bitmaps (TargaSharp.Drawing)

using TargaSharp.Drawing;

TgaFile tga = TgaDrawing.FromBitmap(bitmap, useRle: true);
using Bitmap bmp = tga.ToBitmap();
using Bitmap? thumb = tga.GetPostageStampBitmap();

Supported formats

Image type Uncompressed RLE
Color-mapped (8-bit index, 15/16/24/32-bit palette) ✓ ✓
True-color 16 (A1R5G5B5), 24, 32 bpp ✓ ✓
Grayscale 8 bpp, 16 bpp (8 + 8 alpha) ✓ ✓

All four image origins (bottom-left, bottom-right, top-left, top-right), legacy TGA 1.0 files without a footer, and every TGA 2.0 extension field are read and written.

Errors

Exception When
TgaFormatException Input is not a well-formed TGA (truncated, sizes don't add up)
TgaValidationException The in-memory file violates the spec and cannot be written; .Errors lists every violation
ArgumentException / ArgumentOutOfRangeException A field setter was given an out-of-range value (ASCII-only strings, 4×80 comment lines, alpha bits ≤ 15, …)
NotSupportedException TgaDrawing.FromBitmap given a PixelFormat it cannot convert

Both TGA exceptions derive from TgaException.

Building

dotnet build TargaSharp.sln
dotnet test TargaSharp.sln

Requires the .NET 10 SDK (global.json). dotnet build -c Release also produces the NuGet packages.
