File Formats: TIFF (Tagged Image File Format)

TIFF (Tagged Image File Format)

TIFF is a tag-based file format designed to promote universal interchanges of digital image data. Because TIFF files do not have a single way to store image data, there are many versions of TIFF. LEADTOOLS supports the most common TIFF formats. The usual file extension is TIFF for single-image files, and MPT for multipage files (which can contain many images). TIFF files can contain many comment fields of various types. You can use the ReadComment method to read comments in an existing file. Before writing a file, you can use the Comments property to set an array of comments to be saved in the file.

LEAD supports loading and saving multi-page files in this format.

LEADTOOLS can read and write TIFF files that use RGB, CMYK, or YCbCr color space. LEADTOOLS can also read and write files with PackBits compression.

LEADTOOLS can also read and write files with Lossless JPEG compression for 8, 12, and 16-bit grayscale and 24-bit color spacing.

You can read and write 12- bit grayscale. (Document/Medical toolkits only)

Regions are saved automatically inside TIFF files. For more information, refer to Saving a Region. Note, however, that the ability to save a region inside a TIFF file must be unlocked, which requires a Document Imaging or Medical Imaging toolkit.

Only TIFF and DICOM file formats are capable of saving images that have been window-leveled. Images can be window-leveled by using WindowLevel and specifying RasterWindowLevelMode.PaintAndProcessing for the flags parameter or by loading an image from a file format that supports window-leveling. If a window-leveled image is saved as any other file format, the image data will be converted before being saved. For more information, refer to Saving Window-Leveled Images.

The file constants associated with this file format are:
