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.
