Hello,

When I convert the picture attached (bmp) to TGA and then to bmp again, the image becomes defective.

Link to file:
https://www.dropbox.com/...4VrudSbchKYR3xOC-Na?dl=0


Code used:

Code:
public static void Main(string[] args)
{
	var image = File.ReadAllBytes(@"D:\4055.bmp");

	var tga = ExportToTga(image);
	var bmp = ExportToBmp(tga);

	File.WriteAllBytes(@"D:\img_exported.bmp", bmp);

}

private static byte[] ExportToTga(byte[] image)
{
	using (var tgaExported = new MemoryStream())
	using (var reader = ImageReader.Create(new MemoryStream(image)))
	using (var writer = new TgaWriter(tgaExported))
	{
		writer.Compression = CompressionType.Rle;
		writer.ReducedPrecision = true;

		Pipeline.Run(reader + writer);

		return tgaExported.GetBuffer();
	}
}

private static byte[] ExportToBmp(byte[] image)
{
	using (var bmpExported = new MemoryStream())
	using (var reader = ImageReader.Create(new MemoryStream(image)))
	using (var bitmap = reader.Frames[0].GetBitmap())
	{
		bitmap.Save(bmpExported, new BmpSettings());

		return bmpExported.GetBuffer();
	}
}


Thank you,

Kind regards
Fedor
