TIFF (Tagged Image File Format) Reader/Writer

Licensing options for this format begin with FME Professional Edition.

The TIFF Reader/Writer module provides FME with access to data in the TIFF format.


TIFF uses the data reading and writing functionality of the Geospatial Data Abstraction Library. The first element of the raster corresponds to the lower-left hand corner of the raster. For each raster, there is only a single feature returned, since this feature will contain the entire raster.

TIFF (Tag Information File Format) files can be raster files containing elevation data, or image files containing color data. Each elevation sample in a raster file is a point in a single FME raster feature, while each pixel color value in an image file is a value in a single FME raster feature.

The reader and writer support band types of Byte, UInt16, Int16, UInt32, Int32, Float32, and Float64. Classified (Paletted) images will return class dictionary (palette) information associated with the band.

The reader and writer produces non-georeferenced TIFF files, but the writer can generate an Esri world file with the extension .tfw.

The TIFF writer supports the following options:

  • Tiled TIFF files: This option specifies whether to create tiled or stripped TIFF files.
  • Tile/Strip size: These options specify the size of tiles or strips to create.
  • Compression (jpeg/lzw/pack-bits/ccitt-rle/ccitt-fax3/ccitt-fax4/none): This option sets the compression to use.
  • JPEG Compression Level

    This option sets the JPEG quality when using JPEG compression.

    Note: Repeatedly reading and saving files may decrease the quality for this format. In addition, Workbench may not know which format data comes from, and whether it used lossy compression. If you know that source data comes from files with lossy compression, you should also set the compression level to 0. Although this compression still does not guarantee the exact copy of the source file, the output will be very close to the original.

  • JPEG Compression Level: This option sets the JPEG quality when using JPEG compression.
  • Arbitrary bit depths: This option allows writing datasets with any bit depth between 1 and 32.

  • BigTIFF: Enabling this option allows an output TIFF file larger than 4GB.
  • Interleaving: The organization of the bands in the file.
  • Photometric Interpretation: The color space of the image data.
  • Byte order: The byte order used in the file.
