Examples

EgamiContext strict = EgamiContext.Default with
{
    Limits = SafetyLimits.Default with { MaxPixels = 25_000_000, MaxTotalBytes = 256L * 1024 * 1024 },
};

try
{
    // Read the header first: cheap, and it rejects what you do not want before any pixel memory is used.
    RasterInfo info = Raster.Probe(upload, strict);
    if (info.Width > 8000 || info.Height > 8000)
    {
        throw new InvalidDataException("Too large.");
    }

    using Raster image = Raster.Load(upload, strict, new ReaderOptions { Recovery = RecoveryMode.Strict });
    Console.WriteLine($"{info.Format.Name} {image.Width} × {image.Height}");
}

    Console.WriteLine("Not an image format we accept.");
}
catch (LimitExceededException e)
