From Nekoware

exrtools is a set of simple command-line utilities for manipulating with high dynamic range images in OpenEXR format. OpenEXR is a high dynamic-range (HDR) image file format developed by Industrial Light & Magic for use in computer imaging applications.

exrtools was developed to help experiment with batch processing of HDR images for tone mapping. Each application is small and reasonably self-contained such that the source code may be of most value to others.

exrtools currently only works with RGBA OpenEXR files. As well, the code assumes that the EXR files and PNG files all use sRGB primaries and gamma function.

exrtools and its source code is released under an MIT-style license and may be used in both commercial and non-commercial applications without fee. See the license here (http://scanline.ca/exrtools/COPYING.exrtools) or in the source distribution below.

The Application contains the following programms: exrblur - Applies a gaussian blur to an image. exrchr - Applies spatially-varying chromatic adaptation to an image. exricamtm - Performs tone mapping using the iCAM method. exrnlm - Performs non-linear masking correction to an image. exrnormalize - Normalize an image. exrpptm - Performs tone mapping using the photoreceptor physiology method. exrstats - Displays statistics about an image. exrtopng - Converts an image to PNG format. jpegtoexr - Converts an image to EXR format from JPEG. pngtoexr - Converts an image to EXR format from PNG. ppmtoexr - Converts an image to EXR format from PPM. Works with the 16 bit per channel PPM files from dcraw for digital cameras with RAW modes.

[edit] Installing the package

Download and install the neko_exrtools-0.4 (version 1) tardist package from the Nekoware repository.

Installation of the precompiled binary package can be achieved using either Software Manager or inst: In the case of inst, all that's required is the command:

~ $ inst -f /path/to/neko_exrtools-0.4.tardist
install all
keep *.opt.src
go
quit

You will need "root" privileges to install the software.

A list of all files is installed by this package is available.

[edit] Package Dependencies

The following additional packages are required to run this software correctly:

• neko_libpng (version 2)

• neko_zlib (version )

• neko_libjpeg (version 2)

• neko_openexr (version 1)

[edit] Package Incompatibilities

The following packages are marked as incompatible.

• No incompatibilities.

[edit] Package Layout

Default indicates whether the subsystem will be installed if "install standard" (or similar) is used. Order is used if any given subsystem must be installed before others.

[edit] Compiling

As for the majority of Nekoware packages, the 7.4.x release of SGI's MIPSpro Compiler suite has been used to build this package.

The Application contains the following programms:
exrblur - Applies a gaussian blur to an image.  
exrchr - Applies spatially-varying chromatic adaptation to an image.  
exricamtm - Performs tone mapping using the iCAM method.  
exrnlm - Performs non-linear masking correction to an image.  
exrnormalize - Normalize an image.  
exrpptm - Performs tone mapping using the photoreceptor physiology method.  
exrstats - Displays statistics about an image.  
exrtopng - Converts an image to PNG format.  
jpegtoexr - Converts an image to EXR format from JPEG.  
pngtoexr - Converts an image to EXR format from PNG.  
ppmtoexr - Converts an image to EXR format from PPM. Works with the 16 bit per channel PPM files from dcraw for digital cameras with RAW modes.
