FPX (FlashPix)

Extensions: FPX

Creator: Eastman Kodak, Hewlett-Packard, Microsoft, Live Picture

Description:

FlashPix is a multi-resolution raster image file format with a pyramidal hierarchy of resolution "layers" organized and described using structured storage techniques (a la OLE). FlashPix includes scripting operators (called "viewing parameters") that can be stored in a separate file, then rendered against the original, unmodified image bits. FlashPix allows the application and user to gain access to exactly the "right" resolution of image information; no more or less than is needed. For instance, edits can be made and stored into a script, then the script quickly rendered on the screen res image for extremely fast updates. Rendering at higher res isn't done until needed, at print time, for instance. FlashPix is ideally suited for working with images across the Internet because low res screen images can be downloaded, manipulated, then the scripts can be sent back so that all high-res work is done on the remote server. This is very efficient of net bandwidth. A key benefit of FlashPix is that images can be used and worked with on a PC with much less RAM and processor speed than is needed traditionally to work on photo-quality raster images.

This format is supported by a number of paint programs on IBM computers including DeluxePaint from Electronic Arts. There is also a HAM (Hold and Modify) version of this format which uses an encoding scheme that packs the approximate equivalent of 12 bits of image data into 6 bits per pixel. Initially, HAM images could only be one of two sizes (320x200 or 320x400) but now many illustration and page layout programs can handle non-standard HAM images using non-square pixels.

xv read and write.

JPEG Software decompress and compress (djpeg, cjpeg).

PhotoShop read and write.

DeBabelizer read only.

Description:

Joint Photographics Experts Group (JPEG) compression economizes on the way data is stored and also identifies and discards "extra" data, that is, information beyond what the human eye can see. Because it discards data, the JPEG algorithm is referred to as "lossy." This means that once an image has been compressed and then decompressed, it will not be identical to the original image. In most cases, the difference between the original and compressed version of the image is indistinguishable. One advantage of JPEG compression is that you can select the quality when compressing the image. The lower the quality, the smaller the image but the more different it will appear than the original.
