I am trying to compare 2 float values using if
the foll code does not work
a=1.4
b=1.6
if test $a -gt $b
then
echo "$a is max"
else
echo "$b is max"
fi
does -gt work for floating point numbers, if not how do go about for my requirement? can i use bc ? pls help
thanks in advance... (2 Replies)

pfsview(1) General Commands Manual pfsview(1)NAME
pfsview - Viewer for high-dynamic range images in pfs format
SYNOPSIS
pfsview [--window_min <log_lum>] [--window_max <log_lum>]
DESCRIPTION
pfsview is a QT application for viewing high-dynamic range images. It expects pfs stream on the standard input and displays the frames in
that stream one by one.
pfsv script can be more convienent to use if hdr images are to be displayed without any prior processing.
DYNAMIC RANGE WINDOW
To show high-dynamic range data on a low-dynamic range monitor, pfsview uses concept of a dynamic range window. The dynamic range window is
the highest and lowest value that should be mapped to black and white pixel. Values above or below the window are clipped (see clipping
methods below). The dynamic range window is displayed in pfsview as a blue area on the dynamic range scale (second toolbox from the top).
The window can be moved, shrunk and expended using a mouse or a keyboard.
CLIPPING METHODS
Currently, two clipping methods are available (see View menu):
Simple clipping
The values above and below the dynamic range window are displayed as black or white.
Color-coded clipping
The values above the dynamic range window are displayed as yellow and below the window as green. This is helpful to see which parts
of the image do not fit into the selected dynamic range.
Keep brightness and hue
This method tries to preserve brightness and hue while sacrificing color saturation when the colors exceed the RGB color gamut. Col-
ors are desaturated in the RGB color space towards the neutral color (D65) of the corresponding luminance.
MAPPING METHODS
High-dynamic range data are usually better visualized using non-linear scale, for example a logarithmic or a power function. pfsview offers
several such scales, shown in View menu. Gray-scale values for each mapping method are computed by the formulas:
LINEAR: y = (x-min)/(max-min)
GAMMA: y = [ (x-min)/(max-min) ]^gamma
LOGARITHMIC: y = (log10(x)-log10(min))/(log10(max)-log10(min))
where y is the gray-scale value after mapping, x is an input HDR value, min and max are lower and upper bounds of the dynamic range window.
OPTIONS --window_min <log_lum>
Lower bound of the values that should be displayed or minimum value of the dynamic range window. The value should be given in log_10
units, for example -1 if the lower bound should be 0.1 (10^-1).
--window_max <log_lum>
Upper bound of the values that should be displayed or minimum value of the dynamic range window. The value should be given in log_10
units, for example -1 if the upper bound should be 0.1 (10^-1).
EXAMPLES
pfsin memorial.hdr | pfsview
See the memorial image.
pfsv memorial.hdr
The same as above, but using the utility script 'pv'.
