25. XNA & MonoGame Tiff Importer

       By default, the XNA Framework does not natively support tiff based image files. To use the native content pipeline importers, you will need to use PNG, JPG, DDS, TGA, or BMP. The following link shows you how to create a tiff importer.

Make sure you add the System.Drawing Reference to the Importer.

Here is the Source Code:

using System;
using System.Collections.Generic;
using System.Drawing;

using System.Linq;
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework.Content.Pipeline;
using Microsoft.Xna.Framework.Content.Pipeline.Graphics;
using Microsoft.Xna.Framework.Content.Pipeline.Processors;

// TODO: replace these with the processor input and output types.
using TInput = System.String;
using TOutput = System.String;

namespace TiffLib
    /// <summary>
    /// This class will be instantiated by the XNA Framework Content Pipeline
    /// to apply custom processing to content data, converting an object of
    /// type TInput to TOutput. The input and output types may be the same if
    /// the processor wishes to alter data without changing its type.
    /// This should be part of a Content Pipeline Extension Library project.
    /// TODO: change the ContentProcessor attribute to specify the correct
    /// display name for this processor.
    /// </summary>
    [ContentImporter(".tif", ".tiff", DisplayName = "TIFF Importer", DefaultProcessor = "TextureProcessor")]
    public class TiffImporter : ContentImporter<Texture2DContent>
        public override Texture2DContent Import(string filename, ContentImporterContext context)
            Bitmap bitmap = Image.FromFile(filename) as Bitmap;
            var bitmapContent = new PixelBitmapContent<Microsoft.Xna.Framework.Color>(bitmap.Width, bitmap.Height);

            for (int i = 0; i < bitmap.Width; i++)
                for (int j = 0; j < bitmap.Height; j++)
                    System.Drawing.Color from = bitmap.GetPixel(i, j);
                    Microsoft.Xna.Framework.Color to = new Microsoft.Xna.Framework.Color(from.R, from.G, from.B, from.A);
                    bitmapContent.SetPixel(i, j, to);

            return new Texture2DContent()
                Mipmaps = new MipmapChain(bitmapContent)
