Universal.Common.Formats.Gif

Library for reading and decoding GIF files - cross-platform, dependency-free.

Quickstart

Gif.Header header = Gif.ReadHeader(stream);
Gif.LogicalScreenDescriptor descriptor = Gif.ReadLogicalScreenDescriptor(stream);

Console.WriteLine($"{header.Version}: {descriptor.Width}x{descriptor.Height}");

Or, for just the pixel dimensions via the shared Universal.Common.Image abstraction:

Dimensions dimensions = new GifDimensionsReader().Read(stream);

And to decode the image data itself to RGBA8 pixels:

DecodedGif decoded = GifDecoder.Decode(File.ReadAllBytes("picture.gif"));

// decoded.Rgba is decoded.Width * decoded.Height * 4 bytes, row-major, R-G-B-A.
Console.WriteLine($"{decoded.Width}x{decoded.Height}");

GifDecoder handles GIF87a and GIF89a, LZW decompression, global and local color tables, and both interlaced and non-interlaced data. Two deliberate limits, both chosen to match PowerPoint's own still-export rendering of an inserted GIF:

  • Only the first image frame is decoded - no animation, no interframe disposal.
  • The Graphic Control Extension's transparent-color-index flag is parsed but not honored - every decoded pixel is fully opaque, and a transparent-flagged index decodes to its literal color table entry rather than to transparency.

Added GifDecoder, decoding GIF87a/GIF89a image data to RGBA8 pixels: LZW
decompression, global and local color tables, and interlaced or non-interlaced data. Two deliberate
limits, both matching PowerPoint's own still-export rendering: only the first image frame is decoded
(no animation or interframe disposal), and the Graphic Control Extension's transparent-color-index
flag is parsed but not honored - every decoded pixel is fully opaque, with a transparent-flagged
index rendered as its literal color table entry.
