fv: New Features
Version 2.4 of fv was released on November
24, 1998. Here is a list of features added since version 2.3 was released
on May 8, 1998:
- Windows 95/98/NT support added via separate binary distribution.
- Based on version 8 of tcl/tk which includes a
built-in bytecode compiler, speeding up execution by a factor of
2.
- Internet support has been added. Files can be read via the http and
ftp protocols. Ftp sites can be browsed with the "Open File" dialog
box.
- Filename completion has been added to the "Open File" dialog box.
Type the initial characters of a file name and press TAB. Fv will
look for a file starting with those characters.
- Basic fv functions (open, display, and plot data) can be controlled
with simple TCL scripts.
- New, empty FITS files can be created. Empty extensions of any of
the 3 types (image, ASCII Table, Binary Table) can be appended to
existing files.
- Checksum keywords can be created or updated when a file is modified.
- Keyboard shortcuts (ctrl-c and ctrl-v) have been added for copying
and pasting data in the table display window.
- When displaying an image in POW, double-clicking the image will cause
fv to open the corresponding FITS extension as a table and highlight
the clicked pixel.
- POW can create contour maps of images.
- More curve plotting options have been added to POW. Each curve can
have its own line style/width, point shape/size, and color.
- The Edit Graph dialog boxes have been modified to make them simpler,
more intuitive, and more powerful. One can easily control the contents
of a given graph, the plotting styles of its curves, and the axis
parameters (label, bounds, etc) from a single window.
- Graphs containing images can be rescaled to arbitrary sizes in both
the X and Y directions. (No more snapping to integral magsteps.)
- Removed restriction on the production of mosaics from images with
different pixel sizes.
