Qtpfsgui 1.9.1 (Development branch)
04-10-2008
Qtpfsgui is an open source graphical userinterface application that aims to provide aworkflow for HDR imaging. Supported operationsinclude: creations of a HDR file from a set ofimages of a scene taken at different exposuresettings, tone-mapping an HDR image into a commonLDR image format (e.g JPEG or PNG), and loading,saving, and rotating existing HDR images.License: GNU General Public License (GPL)Changes:|

pfsintiff(1) General Commands Manual pfsintiff(1) NAME
pfsintiff - Load images or frames in several variants of TIFF format (both LDR and HDR) SYNOPSIS
pfsintiff (<file> [--linear] [--frames <range>] [--skip-missing]) [<file>...] DESCRIPTION
pfsintiff command loads images in TIFF format and writes pfs stream to the Standard Output. The pfs stream is usually piped to another pro- gram for further processing. To detect the format automatically based on the extension, use pfsin command. Both the standard LDR tiff and extended HDR (logLuv encoding http://www.anyhere.com/gward/pixformat/tiffluv.html); Note that both LDR and HDR tiff files provide photometric data (ie linearly related to luminance). The 'LUMINANCE' tag is set to 'RELATIVE', also the '--linear' switch is ignored. To read images from standard input use a single dash '-' instead of filename. The images are read until EOF is reached. Each file can contain a %d pattern, which is substituted with frame numbers. The pattern has the same syntax as C printf command. For exam- ple, you can use %04d to make the frame number four digit with proceedings zeros. You can select the frames using the following options (the options must be always given after the file name): --frames <range> Range is given in mathlab / octave format: startframe:step:endframe Frame numbers start with startframe (default 0), are increased by step (default 1) and stop at endframe You can skip one of those values, for example 1:100 for frames 1,2,...,100 and 0:2: for frame 0,2,4,... up to the last file that exists. --skip-missing Skip up to ten frames in a row if corresponding files are missing. Otherwise the program stops reading sequence at the first file that does not exists. This switch does not apply to the first frame in a sequence. This switch can be useful if there is a rendered animation where some of the frame has not been generated. --linear Ignored for compatibility with pfsinppm. EXAMPLES
pfsintiff frame%04d.tif --frames 0:10 | pfsview Read frames from files frame0000.tif, frame0001.tif, ..., frame0010.tif and show them using pfsview. BUGS
