Ideally the image file should be stored on some filesystem other that the filesystem whose data it contains, to ensure that its data is accessible in the case where the filesystem has been badly damaged.
The size of an ext2 image file depends primarily on the size of the filesystems and how many inodes are in use.
Image files tend to be quite compressible; an image file taking up 32 megabytes of space on disk will generally compress down to 3 or 4 megabytes.

 Raw image file format
Images and pectral images or data cubes that are written in the raw file format are just a continuous string of numbers – no header, no compression, no encoding to eliminate blocks of zeros, etc.  Data cubes can be stored image by image, or spectrum by spectrum.  Single images are stored row by row.
The.rpl file or "Ripple" file, is a short ASCII (text) file listing the parameters that characterize a.raw file with the same name.
Rows, etc refer to the image and not the file, which is just one long string of bytes.

A RAW file, as the name implies, is RAW data from the camera - recorded without having various camera settings applied (like white balance, sharpening, etc.).
RAW files are proprietory - meaning that the various camera manufacturers have their own RAW file format.
A RAW file is a bit like a film negative, and a JPEG file could be likened to the photograph that you get back from the lab.

Like all file formats supported by IFL you access raw images via the generic object class (or the ilFileImg object for IL users).
To read a file in raw format you must use the format override suffix, '#raw', and the format specific argument suffic, '%' to tell IFL what the data format is since it can't determine it from a file header.
For example, to open a luminance, unsigned char, 512 by 512 image in a file named 'image.raw' you would use the file specification: image.raw#raw%size=512,512%colormodel=luminance or (assuming the name is used on a command line in csh): image.raw#raw%'s=512,512 c=lum' The full set of parameters and their possible values are enumerated in the folowing sections.

 Fujifilm FinePix S2 Pro Review: 12. Software: Digital Photography Review
In addition to the raw CCD data the header of a RAW file will also contain exposure and setting information such as selected white balance, tone, sharpening etc. all of these parameters are used by the raw conversion software to produce the final image.
RAW image files can be seen as a 'digital negative', they are untouched by the camera processing algorithms and are therefore open to improved image processing facilitated by the additional processing power of a desktop computer and ever improving processing algorithms.

 ExposedBrain.com: PHOTOGRAPHY in THE RAW by Trevor   (Site not responding. Last check: 2007-10-20)
Cameras supporting the RAW format [which is actually a loose amalgamation of as many as fifteen independent and non-compatible micro-formats] traditionally rest within the more complicated, advanced, and expensive ranks of photographic equipment.
It enables you to go back to an image you'd directly associated with the reality of an event, and tweak it to the point of virtual unrecognizability, all the while maintaining a quality that you would assume would immediately classify it as "realistic".
RAW Photography coerces you into a particular variation on the realization that your perceptions are nothing more, nothing less, than a situationally and aesthetically subjective take on reality.

 USGS MIPS Export Documentation
In exporting a raw binary image file, one of three different interleaving formats can be used.
Files created with this format have sample 1 written out to the output file for the first image, then every other image, and then sample 2 and so on.
The output image will be created as either an image file in the BMP or TIFF image format depending on the format chosen.

 Re: Ian - one last noise request ...
At its most basic definition, a RAW file will just contain the brightness and colour values for each pixel as determined by the analogue to digital conversion process converting the amplified voltages off each pixel photodiode on the sensor chip.
I'm not familiar with all the RAW file formats out there, but common to all is the ability to apply your own choices concerning colour, contrast and sharpness from virgin (previously unprocessed) image data.
RAW image viewers will apply some processing, maybe by default, so at least the image doesn't look too weird, but you still have access to the underlying unprocessed data, which you can adjust as you like.

This file is a Macintosh Disk Image, similar to an.img file, but it does not require the use of Disk Copy.
Tar archives files but does not compress them, so sometimes.tar files are compressed with other utilities, which produces extensions like.tar.gz,.tar.Z, and.tgz.

An image mapped once for a particular monitor, does not have to be the optimum solution even for another monitor, and especially not for a printer or some other device.
It is true that storing a raw image as the array of float triplets will demand a huge amount of storage place (96 bits per pixel - four times the usually necessary 24 bits).
Fortunately there are currently three freely available raw image formats that overcome the size problem, at the cost of reduced accuracy.

 Paul Thurrott's SuperSite for Windows: Longhorn Raw Image Support
Raw image files are often described as digital negatives, because they are uncompressed, unprocessed files that accurately portray the data captured by the sensor in a high-end digital camera.
Raw images, meanwhile, appear in XP with an ugly default icon, and if you try to open one, the system won't know what to do with it.
Aside from the obvious, Longhorn's support of Raw images is important because, for the first time, a common Raw image format is being supported by camera makers and, conspicuously, by Adobe, a company many might have expected to resist Microsoft's efforts.

 DIGITAL CAMERAS-Image Compression & File Formats
Raw image file formats Since compression degrades images to some degree, some cameras are able to use an uncompressed format to preserve as much of the captured image quality as possible, this severely reduces the storage capacity of the cameras.
In some cases, these raw formats are unique to cameras and are not supported by many other programs, use them only when image quality is indispensable.
TIFF (.TIF) TIFF (Tag Image File Format) was developed by Aldus Corporation for saving images created by scanners, photo editing programs, frame grabbers etc. This format is mostly used for transferring images and has gained wide acceptance in this regard.

 File Naming Conventions   (Site not responding. Last check: 2007-10-20)
The file names are defined so as to allow the unique identification of the information stored in the file (ref. 14).
Files with extensions include the keyword both for the main data set and for the extensions so that the FITS reader could either store the information in a single file or store the main data set and the extension in different files.
Images which are processed as both high dispersion and low dispersion would therefore have both sets of files in the archive.

Use of masks (alpha channels) to specify an area of the image that should be saved at a lower rate of data compression (loss of image information) than other areas of the image that are of less interest to the viewer.
Note: The file is being saved with a wavelet algorithm (similar to the type of compression pioneered by Luratech), so it will take a bit longer than usual for the file to write to disk.

 shutterbug: Raw File Format And Image Quality
The result of a digital camera’s post-capture image processing (JPEG compression generated from sRGB color space) is that the color in the file opened by a typical consumer software application with a PC is much more restricted in color image information than what was captured by a digital camera’s sensor.
Click on what should be a fl and a white pixel in the open image, or move the fl and white arrows at the outer bottom edges of the histogram window to where the image data begins, indicated by the fl graph shape.
I was particularly impressed with images made in fairly soft light, where the Foveon X3 sensor chip was able to record and distinguish very subtle subject color differences that required a minimum of post-processing color correction.
