| BMP |
Originated by
Microsoft, BMP supports 1, 4, 8 and 24-bit images. 4 and 8-bit images
may be compressed using simple run length encoding. |
| CALS |

government spec standing Computer-Aided acquisition and logistics
support. Data is CCITT group 4 compressed. 1-bit only. |
| C4 |
JEDMICS |
| DIB |
Standard
Windows 3.1 and Win95 Device Independent Bitmap. Supports 1, 4, 8 and 24
bits. |
| DCX |
Intel created
this format as a multipage .PCX format. Each page is a .PCX file in
which can be 1, 4, 8 and 24 bit. Uses a type of run length encoding
(only the first page will be read). |
| EPS |
Encapsulated
Postscript originated by Adobe. EPS is a very complex interpreted
language. TracTrix does not attempt to interpret the image but looks for
an embedded .TIF file in the image. Sometimes called a bitmap
representation file. |
| GEM IMG |
Originated by
Digital Research for storing 1-bit images. Uses run length encoding
similar to pack bits. |
| GIF |
(Read only)
Created by CompuServe for compressing 2, 3, 4, 5, 6, 7 and 8-bit palette
images. Uses the LZW algorithm. |
|
GIF_INTER-LACED |
Same as GIF
except stores the rasters in an interlaced order. Stores every 8 lines
then every 4 then every other until the image is filled. |
| GX2 |
Originated by
Brightbill Roberts for ShowPartner DOS applications. Supports 4 and
8-bit images. Simple run length encoding technique. |
| HALO CUT |
Cut images
are only 8 bits per pixel and the palette is stored in a separate file.
Originated by Media Cybernetics. |
| ICO |
Microsoft
icon format. Contains a standard device independent bitmap with a new
header on top. Supports 1 and 4 bits uncompressed. |
| IFF |
Used on the
Commodore Amiga computers for native bitmap format. Uses a run length
format for 1, 4 and 8-bit palette images. |
| IOCA |
Image object
content architecture. IBM format which uses CCITT G3, G4 and IBM MMR
formats. 1-bit only. |
| JEDMICS C4 |
JEDMICS
(Joint Engineering Data Management Information and Control System) is
the Department of Defense standard repository for the management and
control of engineering data. JEDMICS provides the means for DoD
organizations to efficiently convert, protect, store, manage, retrieve
and distribute information previously stored in hard copy or in limited
legacy systems. |
| JPEG |
Joint
Photographics Experts Group. This was a group spearheaded by Kodak for
24, 32-bit and 8-bit gray scale lossy compression. |
| LASERVIEW
CCITTG4 |
Compression
for documents originated by LaserData Corp. 1-bit images only. |
| MACPAINT |
The original
Apple bitmap file format. All MacPaint images are 720 x 576 pixels 1
bit. |
| MSP |
Microsoft
Paint program bitmap file format. Supports 1-bit images. Uses a type of
RLE compression found also in compressed .BMP files. |
| PCX |
Zsoft bitmap
file format. Similar to pack bits compression. Supports 1, 4, 8 and
24-bit images. |
| PNG |
Originated by
CompuServe to replace the .GIF file format. Uses the Huffman encoding
variant. Supports 1, 4, 8, 15, 16, 24, and 32-bit images. Also supports
interlaced and transparency. |
| PSD |
Adobe
Photoshop format for storing 1, 4, 8, 16, 24 and 32-bit images. Can be
compressed or uncompressed. Images may also be stored as CMYK data or
RGB. |
| PCD |
Kodak photo
CD format. Supports only 24-bit images. |
| PICT |
Apple
Macintosh bitmap file format. These images may contain vector
information such as lines and circles. Only the bitmap portion of data
is opened by TracTrix. |
| RAST |
Sun raster
format. Supports 1, 8, 24 and 32-bits. Run length encoded format. |
| TARGA |
Targa format
was created by Truevision for their image capture boards. Targas support
8, 16, 24 and 32-bits. Usually uncompressed data but may use run length
encoding. |
| TIFF |
Tagged Image
File Format. Created by an independent group and was supported by Aldus.
.TIF files can be any number of bits per pixel, planes and several
compression algorithms. The byte order may be Intel or Motorola format.
The bytes may also be filled from right to left or left to right.
Compression may be uncompressed, pack bits, modified Huffman, CCITT G4,
CCITT G3, CCITT G3-2D or JPEG. Also LZW read-only. |
| WMF |
Microsoft
Windows Metafile format. These files may contain vector information such
as lines and circles. Only the bitmap data is opened. This is in the
form of a standard windows DIB. May be 1, 4, 8 and 24 bit. The 4 and
8-bit images may be compressed using the Microsoft RLE compression as in
.BMP files. |
| WPG |
WordPerfect’s
metafile format. This is similar to the WMF file format in that it may
contain vector information. Supports 1, 4, 8 and 24 bit images. Again
only the bitmap data is opened. The vector information is ignored. |
| XBM |
Xwindows file
format which encodes each pixel as an ASCII byte. Only supports 8-bits
per pixel. |
| XPM |
Xwindows
bitmap file format stored as ASCII data. |
