exrtools 0.4

exrtools project 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. Fixing this is not very difficult, and the code to fix allows for some interesting possibilities. That said, I do not have time right now, so this will have to wait. 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. Applications 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. Whats New in This Release: - Added the ppmtoexr application to convert from PPM formats including the 48 bit per pixel format output by dcraw..
