About

LargeTIFFTools is a collection of software that can help managing (very) large TIFF files, especially files that are too large to fit entirely into your computer's memory. It is composed of the following programs:

tiffmakemosaic opens a TIFF file and makes a mosaic out of it.
tifffastcrop crops (extracts) a rectangular region from a TIFF file without opening the whole image into memory and saves it as a TIFF, JPEG or PNG file.
tiffsplittiles copies the tiles of a tiled TIFF file into independent files (one for each tile).

Getting the software

The software is open source, distributed under the GNU General Public License v. 3.0. It uses noticeably the libtiff and libjpeg or libjpeg-turbo software, made free and open by its authors, which we acknowledge.

You can get the software through download (see the links in the frame). We provide some pre-compiled versions. The 32-bit Windows version should run under all versions of Windows (XP, Vista, 7; either 32- or 64-bits) but will produce images which require at most ca. 1 GiB memory. The 64-bit version goes beyond that limit.

If you install the software from source, you need the following installed libraries: libtiff (we recommend a version >= 4.0.0) and libjpeg (and possibly other libraries that your version of libtiff might use, e.g. zlib). Basic instructions for installing from source are: extract with tar xfj <file>, compile and install with ./configure ; make ; make install.

Using the software

Under Windows, you can simply drag and drop a TIFF (.tif) file over the .exe file or icon of the relevant program. tiffmakemosaic.exe and tiffsplittiles.exe will open the file and, if appropriate, split it into multiple TIFF image files (while preserving the original). tiffmakemosaic-j.exe does the same as tiffmakemosaic-j.exe, but stores the resulting images into JPEG files (option -j is hardcoded). For options, please refer to the documentation of each program for details.

On all platforms (including Windows, Linux, Mac OS X), you can also use it with a command line. Open a shell (e.g. command interpreter, Terminal.app, xterm...) and launch the program by typing its name (preceded by its path if needed) followed by a space then the path to the TIFF file. The resulting TIFF or JPEG file(s) will be produced in the directory where the original TIFF file resides.

A typical use is for anatomopathology or microscopy slide images, like the one that the NDPITools produce.

Performances

In principle, generating pieces from a large TIFF file can also be achieved with several tools, as tiffcrop from the libtiff, ImageMagick, and GraphicsMagick (one has to first compute and specify explicitly the dimensions and positions of the pieces, though). However, most of the software start with opening and deciphering the whole image either in memory or in a huge temporary file on the disk, which makes them quite slow or often unable to complete the task by lack of memory.

In contrast, tiffmakemosaic, tifffastcrop and tiffsplittiles avoid opening the whole image, which yields speedup and guarantees successful termination of the process even on computers with modest memory. Eg. to make a mosaic of 64 JPEG files requesting less than 512 Mib of memory to open from a RGB image of 103168x63232 pixels, on a computer with 16 Gib of RAM and an i5 CPU, tiffmakemosaic needs 2.5 minutes while GraphicsMagick needs 70 minutes.

Non-exhaustive list of enhancements

Release 1.3.6: tifffastcrop is now able to deal with many bit-depths (e.g. RGB with alpha channel, or 1 bit-per-pixel black and white images, or 4 bits-per-pixel grayscale images...) and to write PNG files in addition to TIFF and JPEG files. Now, it tries to guess the output file format from the output filename, if any.
Release 1.3.7: the software is able to build even with version 1.2 of the libpng library.
Release 1.3.8: improved exit codes especially when input files are corrupted; fixed a regression preventing cross-compilation for Windows; fixed syntax errors in manpages.
Release 1.3.9: tifffastcrop now supports Fax-like compression; corrected a bug in tiffmakemosaic in the case of lossless compression and non-zero overlap.
Release 1.3.10: further support by tifffastcrop and tiffmakemosaic of Fax-like compression.

The following software packages display or manipulate the relativelysimple class of FITS data files that containing 2-dimensional images, often of celestial objects in the night sky. It should be noted that FITS is a very generaldata format that is used for many different typesof astronomical data sets, so these packages are not necessarily capable ofreading every type of FITS file.Developers of new image display programs should be aware of the special requirements foreffectively displaying FITS images.

Netpbm - a package of graphics programs and programming library. Thedocumentation is on-line.In particular, see the fitstopmnandpmntofits programs. To first order, the following command converts a jpeg image to a FITS image on most Linux systems:
where 'djpeg' is available in the libjpeg RPM package.

SAOImage ds9 - this FITS visualization application from SAO allows the image tobe saved as a jpeg, tiff, png, or ppm file on disk (use File->Saveas->Image...). This currently requires Ghostscript version 6.5 or higherin the path. From there one can go to gif format using xv. Anotheroption to is save the image as Postscript (File->Print...->File...) andthen use Ghostscript to convert to gif. (Provided gs was build witha corresponding gif driver included). The ds9 operations can bebuilt into a script using the XPA mechanism.
As an example, the following command will open the file 'name.fits', zoom it to fit the window,save it in JPEG format to the file 'filename.jpeg', and then exit
ds9 name.fits -zoom to fit -saveimage jpeg filename.jpeg -exit
Other output image formats, besides jpeg, are png, tiff, ppm, and mpeg.Optionally, one can add '-zscale' or '-geometry 800x800' options to customizethe output image. These options and more are described using 'ds9 --help'.

Notes Regarding the Display of FITS Images

An application intended to render a FITS image for viewing by a user has significantly more responsibility than an application intended to handle other standard image formats (e.g., 'jpg' or 'gif' images). FITS data arrays contain elements which typically represent the values of a physical quantity at some coordinate location. Consequently they need not contain any pixel rendering information in the form of transfer functions, and there is no mechanism for color look-up tables. An application should provide this functionality, either statically using a more or less sophisticated algorithm, or interactively allowing a user various degrees of choice.(See also, ashort introduction to astronomical image processing).

Furthermore, the elements in a FITS data array may be integers or floating point numbers. The dynamic range of the data array values may exceed that of the display medium and the eye, and their distribution may be highly nonuniform. Logarithmic, square-root, and quadratic transfer functions along with histogram equalization techniques have proved helpful for rendering FITS data arrays. Some elements of the array may have values which indicate that their data are undefined or invalid; these should be rendered distinctly.

The data array in a FITS image must have a dimensionality between 1 and 999, the boundaries inclusive, indicated by the NAXIS keyword. The extent of any coordinate axis in a FITS data array may, however, consist of only a single element. Hence an algorithm designed to render two-dimensional images will be capable of displaying a three- or four-dimensional FITS array when one or two of the axes consist of a single pixel.

Three-dimensional data arrays (NAXIS=3 with multiple elements along each) are of special interest. Inspection of the World Coordinate System (WCS) keywords in an image with NAXIS = 3 or more may indicate that one of the axes is temporal. Writers of viewer applications should consider presenting such an image in a fashion akin to that used for an animated GIF. Even in the absence of WCS indication of a temporal axis this time-lapse display technique can be effective, and application writers should consider offering it for all three-dimensional arrays.

A FITS image with NAXIS=1 is a one-dimensional entity such as a spectrum or a time series. Writers of applications intended to handle these one-dimensional FITS images should consider presenting such an image as a graphical plot rather than as a two-dimensional picture with a single row.
