SharpAstro 

Device-Independent input and Rendering library for .NET: surface-neutral drawing primitives, an immutable layout DSL, a widget toolkit, font rasterization (bitmap + SDF) and font fallback, shared by GPU (SDL3 +... More information

Astronomical imaging and device-control library for .NET: cameras, mounts, focusers, filter wheels, cover/calibrators and guiders over ASCOM, Alpaca, ZWO, QHYCCD, Meade LX200, Skywatcher, OnStep and PHD2, plus... More information

Pure-managed PNG encoder + decoder for .NET. Writer: adaptive per-row filter selection (libpng "minimum sum of absolute values" heuristic), 8/16-bit RGBA/Gray. Reader: chunk parsing with CRC validation, color... More information

LALR(1) parser-table generator and runtime in C#. Includes a YAML grammar source generator that emits a typed AST + visitor surface from `*.lalr.yaml` files at build time.

Pure-managed, MIT-licensed C# OpenType / TrueType font loader and rasterizer.

ICC v4 colour-management primitives for .NET image-codec consumers. Bundled sRGB v4 profile (588-byte LittleCMS-generated, ReadOnlyMemory<byte> for embedding in TIFF/PNG/JPEG) plus a WithCicp(...) helper that... More information

Shared abstractions for the SharpAstro image codec family: IImageDecoder (magic-byte sniff + fidelity/zero-copy decode) and IDecodedImage / RasterImage (a codec-neutral decoded raster). Ships the ITU-T H.273... More information

Canon EOS camera control via PTP over USB and WiFi — pure managed C#, no EDSDK binary required

Defines a vendor-neutral access layer for consumer astronomical devices like ZWO, SvBony, etc.

Pure-managed TIFF reader/writer for .NET. Supports multi-page, 8/16/32-bit uint and IEEE-Float samples, Uncompressed/Deflate/ZlibPkzip/LZW, Predictor 2 (horizontal differencing) on read, contig planar config,... More information

Pure-managed JPEG (ITU-T T.81 / ISO 10918) codec for .NET. Decoder: baseline sequential + progressive DCT, restart intervals, 4:4:4 / 4:2:2 / 4:2:0 / arbitrary chroma subsampling, grayscale, YCbCr, RGB-marked,... More information

SDL3 + Vulkan rendering backend for DIR.Lib's Renderer<TSurface>: window, device and swapchain lifecycle, pre-baked SPIR-V pipelines, bitmap and MSDF glyph atlases, and a surfaceless offscreen path for headless... More information

Pure-managed JPEG XR (ITU-T T.832 / ISO/IEC 29199-2) encoder/decoder for .NET. AOT-compatible. The codec core is ported faithfully from Microsoft's jxrlib reference implementation and validated bit-exactly... More information

Pure-managed EXIF metadata reader and writer for .NET. Parses EXIF blobs from JPEG (APP1), TIFF (sub-IFD), and PNG (eXIf chunk) — all of which share the same TIFF-IFD structure. Strongly-typed projection of... More information

Pure-managed JBIG2 (ITU-T T.88) bilevel image decoder for .NET, written clean-room from the specification and aimed at PDF's /JBIG2Decode filter. A PDF-embedded JBIG2 stream is not a file — it has no file... More information

Pure-managed OpenEXR (.exr) reader/writer for .NET. Scanline images, HALF/FLOAT/UINT channels, NONE/RLE/ZIP/ZIPS/PIZ compression. AOT-compatible.

Implements accessing the ZWO ASI, EAF and EFW devices using .NET

Image-codec facade over the SharpAstro codec family: sniff a byte stream's format by its magic-byte signature and dispatch to the matching decoder (PNG, JPEG, TIFF, JPEG XR, OpenEXR, JPEG XL, JBIG2, JPEG 2000,... More information

Pure-managed JPEG XL (.jxl) codec for .NET. Clean-room implementation against ISO/IEC 18181, validated against the Magick.NET (libjxl) oracle. AOT-compatible.

Gain-map ("Ultra HDR") JPEG support: read, assemble, and generate Adobe hdrgm 1.0 / Android Ultra HDR v1 gain-map JPEGs (GContainer XMP + MPF, the form Chromium renders as HDR). Splices metadata around baseline... More information
