Raster
Image File Formats: FlashPix
FlashPix (FPX)
LEADTOOLS FlashPix is included in all LEADTOOLS Raster, Document, Vector, and Medical imaging toolkits. FlashPix extends the input/output functionality
in LEADTOOLS by providing increased versatility in the handling
of color and grayscale images by taking advantage of the
complete FlashPix file structure.
The FlashPix file format was developed through
the combined efforts of Eastman Kodak Company, Microsoft
Corporation, Hewlett-Packard Company, and Live Picture Inc.
It combines the best features of existing formats with object
orientation to make the use of digital color images easier.
The format of a FlashPix file is based on
compound object storage, which allows storage of various
kinds of data. A FlashPix file may consist of several "pages"
where each "page" has storage for a source image,
non-image data in the form of comments, transform data,
and a stamp or thumbnail. Each image is stored as an entire
multi-resolution hierarchy where each resolution in the
hierarchy differs from the next highest resolution by a
factor of 2 in the x dimension and in the y dimension. Non-image
data are treated as comments in FlashPix file format. Comments
are used to store information pertaining to the image, not
actual pixel data. This information may include image title,
image subject, camera manufacturer, scan software version
number, and so forth. In addition to the image itself, FlashPix
files store transform information. This data indicates transformations
which may be performed on the source image. By storing the
transforms, the source image may be stored in its original
state and transformed, using the stored transforms, at your
discretion. A stamp, or thumbnail, provides a small bitmap
representation of a FlashPix image.
LEADTOOLS can read and write the following
bits per pixel: 8, 24.
