TIFF File viewer

Question

I want to develop a TIFF file viewer using C# language. I have complete specification of TIFF. Now what all I should read for doing this??

You can use the LEADTOOLS Imaging Pro SDK in your application https://www.leadtools.com/sdk/products/imaging-pro You can utilize the ImageViewer class to view any LEADTOOLS supported file format (TIFF, PNG, JPEG, etc.). Here is some sample code: using (RasterCodecs _codecs = new RasterCodecs()) { ImageViewer _imageViewer = new ImageViewer(); _imageViewer.Dock = DockStyle.Fill; _imageViewer.BackColor = Color.Bisque; this .Controls.Add(_imageViewer); _imageViewer.BringToFront(); ImageViewerPanZoomInteractiveMode panZoom = new ImageViewerPanZoomInteractiveMode(); _imageViewer.InteractiveModes.Add(panZoom); _imageViewer.Zoom(ControlSizeMode.FitAlways, 1.0, _imageViewer.DefaultZoomOrigin); // Set image to viewer _imageViewer.Image = _codecs.Load(@ "FILE PATH TO TIFF IMAGE" ); }

I'd also like to share my single and mutipage c# tiff image viewer codes for you. in oder to better understanding how to manipulate, here i am going to give you some tutorial and samples.

I take it that you are interested in multipage tiffs; this might get you started: using System; using System.Collections.Generic; using System.Text; using System.Drawing; using System.Drawing.Imaging; using System.Windows.Forms; using System.IO; namespace MultiPageTiff { public class MultipageTiff { public int GetNumberOfPages( string sFileName) { //setup the image Image img = Image .FromFile(sFileName); //get its guid Guid ID = img.FrameDimensionsList[0]; //get the frame dimensions FrameDimension fd = new FrameDimension (ID); //Gets number of pages return img.GetFrameCount(fd); } public Image GetSpecificPage( string sFileName, int iPageNumber) { Image img = Image .FromFile(sFileName); MemoryStream ms = null ; Image returnImage = Image .FromFile(sFileName); try { ms = new MemoryStream (); Guid ID = img.FrameDimensionsList[0]; FrameDimension fd = new FrameDimension (ID); img.SelectActiveFrame(fd, iPageNumber); img.Save(ms, ImageFormat .Bmp); returnImage = Image .FromStream(ms); return returnImage; } catch ( Exception ex) { MessageBox .Show(ex.Message.ToString(), "Error" ); return null ; } finally { ms.Close(); } } public void SetTIFFCompression( string FileName, double QualityPercentage) { //Load a bitmap from file Bitmap bm = ( Bitmap ) Image .FromFile(FileName); //Get the list of available encoders ImageCodecInfo [] codecs = ImageCodecInfo .GetImageEncoders(); //find the encoder with the image/jpeg mime-type ImageCodecInfo ici = null ; foreach ( ImageCodecInfo codec in codecs) { if (codec.MimeType == "image/tiff" ) ici = codec; } //Create a collection of encoder parameters (we only need one in the collection) EncoderParameters ep = new EncoderParameters (); //We'll save image with QualityPercentage as compared with the original //Create an encoder parameter for quality with an appropriate level setting ep.Param[0] = new EncoderParameter (System.Drawing.Imaging. Encoder .Quality, ( long )QualityPercentage); //Save the image with a filename that indicates the compression quality used string newFileName = FileName.ToLower().Replace( ".tif" , "_Quality_" + QualityPercentage + "%.tif" ); bm.Save(newFileName, ici, ep); } } }
