Installation:
This software is a command-line application for 32-bits Windows machine.
To install it, copy "tonemapctr.exe" file into a directory as you wish.
If you want to use it in any directory, please SET PATH of your certain
directory. It should work immediately.
Quick Start:
USAGE: tonemapctr [input hdr] [output ldr] [options]
OPTIONS:
/t: <num> Target Dynamic Range (default: 8.0)
/e: <num> Display Efficiency Factor (default: 0.5)
/g: <num> Target Display Gamma (default: 2.4)
/h: <num> Clamping Level in Highest Level (default: 99.0)
/l: <num> Clamping Level in Lowest Level (default: 0.1)
/s: <num> Standard Deviation Scalar (default: 3.0)
/b: Use Color Gamut Expansion (default: off)
/c: Don't use Smart Highlight Scalar (default: on)
/w: Don't use Gaussian Weighting (default: on)
/m: Use Normalization of Lowest Level(default: off)
/v: Don't show verbose and time (default: on)
SUPPORT:
Input HDR: rgbe, hdr, exr
Output LDR: jpeg, tiff, bmp, png
EXAMPLE:
>>tonemapctr memorial.hdr memorial.png
Tips on Practical Use:
- Ordinary hdr images work well with its diffult parameters. We strongly
encourage you to use this application with its set of default parameters.
You can use tonemapctr in simplest way for general cases like above.
- If you find some artifacts on highlight part of images, you may want to
try options (/c) or (/h 100).
- If you want to get more contrast images, you may want to try options
(/m or /c), which were used for the cited paper.
