BITMAP IMAGE TOUCHUP (Bit) V0.87
Bit V0.87 is now available via anonymous ftp from the following
sites:
monte.svec.uh.edu (129.7.2.23) /pub/bit
ftp.fu-berlin.de (130.133.4.50) /pub/unix/sgi/graphics/bit
What is new ?
- Bug corrections (more than I care to enumerate).
- Image browser.
- Merge/overlay/concatenate images.
- Double buffering.
- More text styles (shadow, engraved and embossed).
- Hooked up FORM library 2.2a.
- Rewrote the event handling and the interface is a lot of faster and
more intuitive.
- Many more minor improvements/enhancements.
What is bit ?
BIT stands for Bitmap Image Touchup and as its name implies, it
is an INTERACTIVE FULL COLOR image VIEWER and EDITOR based on
SiliconGraphics GL and runs on SGI workstations. The major features
of bit include the following (and more):
- View images in 24bits with zooming, panning and slideshow.
- Image browser: making thumbnails on the fly and display.
- Crop a rectangular portion of an image or add a solid border to an image
- Rotate an image by an arbitrary angle with optional anti-aliasing.
- Scale with arbitrary scale factors with optional anti-aliasing.
- Cut & paste between different images. Import images as cut buffers.
- Merge/concatenate/overlay images.
- Annotate an image with text of arbitrary color, size and orientation.
Special symbols can be input as in TeX (e.g., $\alpha$ etc).
- Annotate an image with arbitrarily sized and colored markers, which
include circles, arrows, rectangles etc. and any combinations of
rotation and scaling.
- Edit an individual pixel's RGB value, or a group pixels.
- Arbitrary transformation of pixels. The transformation function can
be specified interactively or by math expressions. the transformation
can be applied to the entire image or a portion of it and to RGB
channels simultaneously or separately.
- Perform convolution with arbitrary externally defined kernels
- Compute pixel-pixel differences between two identically sized images
and show the difference as an image whose histogram can be obtained
to gain more insight into the difference (for example, the difference
between an image and its JPEG-compressed version).
- Smoothing, sharpening, edge detection etc.
- Statistics about an image: histograms, pixel intensities etc.
- Serve as a launch pad for other image processing via key bindings.
Supported image formats:
- IRIS RGB
- JPEG (JFIF)
- CompuServ GIF
- PNM (ppm, pgm, pbm)
- X11 Bitmaps
- TIFF
- PostScript (WriteOnly)
- Sun rasterfile
And compressed version of the above formats.
