What is bit ?
-=-=-=-=-=-=-=-=-=-=-=-=-=
BIT stands for Bitmap Image Touchup and is an integrated interactive
full color image viewer and editor based on IrisGL and runs on
SGI workstations (4D, Indigo, Indy and some PIs).
Note this version of bit is shareware.
--- Feature Summaries---
View
Views many popular image formats in 24bits and combines the
functionalities (and look & feel) of ipaste, gifpaste, jpegpaste. It
also features image panning so that image size larger than window/screen
can be viewed. Further, built-in MPEG player features VCR like control
and in addition you can convert any frame within the MPEG stream to any
bit supported formats.
Editing:
Crop, Rotate(arbitrary angles), Scale, Smooth, Sharpening, Median
filtering, arbitrary convolution with externally defined kernels,
arbitrary color/pixel transformation, including contrast adjustment,
gamma correction, individual pixel editing, pixel swap and histogram
equalization. Merge/overlay/concatenate images with Add/Sub/Diff/XOR/Mask
options on the fly. All image editing functions feature
optional anti-aliasing when appropriate.
Paint & Annotation
Full color, cut & paste, brushes of many shapes, air brushes with
adjustable nozzle size and flow rate, free hand drawing, free hand
polygons, fill and all works with many built-in patterns. Further,
arbitrary text of arbitrary color/orientation can be rendered on top
of an image for annotation.
Supported image formats:
-=-=-=-=-=-=-=-=-==-=-=-=-=-=-
o. IRIS RGB o. JPEG (JFIF)
o. CompuServ GIF o. PNM (ppm, pgm, pbm)
o. X11 Bitmaps o. TIFF
o. MPEG (read only) o. PostScript/EPS
o. Sun rasterfile
And compressed version of the above formats.
What is new in V0.91:
----------------------
1. Bug corrections (GIF encoding, Image Merging and some minor ones)
2. Added a few command line options to make bit more flexible.
(e.g., bit -IN simulates gifpaste/ipaste/jpegpaste/mpeg_play and better)
3. Slightly faster and a lot more stable.
Removed some debugging code and as a result,
4. clock_mailbox is not shown by default.
5. MAIL_AUTHOR upon segmentation faults is off by default
BIT V0.91 is stable enough and unless I have the time and resources
to continue enhancing it, V0.91 will be the last version(at least
for a long while). I, however, will try to correct any bugs found.
