Tagged Image File Format (TIFF and BigTIFF)

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 use 32-bit offsets, so they are limited to 4GB. A newer version of this file format, BigTIFF, uses 64-bit offsets and can create files bigger than 4GB. Not all TIFF readers support BigTIFF files. TIFF and BigTIFF pages cannot be mixed in the same file: all the pages in the file must be either TIFF or BigTIFF. However, you can use LFile::Compact to convert between TIFF and BigTIFF files without recompressing the image data.

You can identify BigTIFF files by examining the FILEINFO.Flags and checking whether the FILEINFO_BIGTIFF flag is set.

Save BigTIFF files by setting ESO2_BIGTIFF in SAVEFILEOPTION.Flags2. The file format is the same for TIFF and BigTIFF files.

The distinction is made using the ESO2_BIGTIFF flag:

BigTIFF and TIFF files have the same capabilities. For simplicity, for the rest of this document both TIFF and BigTIFF files will be referred to as "TIFF".

TIFF files can contain many comment fields of various types. You can use the LFile::ReadComment function to read comments in an existing file. Before writing a file, you can use the LFileSettings::SetComment function to create an array of comments to be saved in the file.

NOTE: To save a region inside a TIFF file, you must have an unlocked  Vector, Document, or Medical Imaging license.

LEADTOOLS also supports the ability to save a vector image as a DXF within a TIFF.

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 and Medical Imaging toolkits)

You can read and write 16- bit grayscale. (Document and Medical Imaging toolkits)

You can read and write 32- bit grayscale. (Document and Medical Imaging toolkits)
