pfsoutjpeghdr(1) General Commands Manual pfsoutjpeghdr(1)NAMEpfsoutjpeghdr - Write images or frames in JPEG-HDR formatSYNOPSISpfsoutjpeghdr (<file> [--linear] [--quality <val>] [--correction <correct>] [--frames <range>]) [<file>...]DESCRIPTIONUse this command to write JPEG file with HDR extension. This software makes use of the High Dynamic Range Imaging Library from Sunnybrook Technologies Inc. (c) Sunnybrook Inc. 2005OPTIONS--quality <val>, -q <val> The --quality setting controls the overall compression/quality trade-off, with 100 being the maximum setting, producing the lowest losses and the largest output files. Quality settings below 70 may result in significant image degradation, and should be avoided in critical applications. Default: --quality=90 --correction <correct>, -c <correct> The --correction setting controls the algorithm used during downsampling of the HDR ratio image data. The default precorrect option compensates for resampling errors by adjusting the tone-mapped image to maximize the accuracy of the HDR result. This option may sometimes induce modest halo artifacts in the tone-mapped image at lower quality settings. If the tone-mapped (backwards compati- ble) image is more important than the HDR version, the postcorrect option may be used, instead. To avoid all artifacts from HDR resampling, specify the fullsamp option. This will result in slightly larger image files. Default: --correction=precorrect --alpha <a>, -a <a>; --beta <b>, -b <b> The --alpha and --beta settings control color desaturation during tone-mapping, which will also permits super-saturated colors to pass through safely. (See the appendix of the paper by Ward and Simmons cited below for details.) Use --alpha < 1 to desaturate colors and --beta > 1 to enhance color saturation contrast. Any input color space will be converted to the standard YCC color space of JPEG, based on the CCIR-709 (sRGB) primaries. Default: --alpha=1, --beta=1.EXAMPLESpfsin memorial.hdr | pfsoutjpeghdr memorial.jpegBUGSPlease report bugs and comments to Rafal Mantiuk <mantiuk@mpi-sb.mpg.de>.SEE ALSOpfsinjpeghdr(1) Subband Encoding of High Dynamic Range ImagerybyWardandSimmons (www.anyhere.com/gward/papers/apgv04) pfsoutjpeghdr(1)
