NAME

       pfsoutppm, pfsouttiff, pfsoutrgbe, pfsoutexr - Write images or frames in one of the several formats

SYNOPSIS

       pfsoutppm (<file> [--srgb] [--frames <range>])  [<file>...]

       pfsouttiff (<file> [--srgb] [--frames <range>])	[<file>...]

       pfsoutrgbe (<file> [--frames <range>])  [<file>...]

       pfsoutexr (<file> [--frames <range>])  [<file>...]

DESCRIPTION

       This  command can be used to write pfs frames piped to standard input in one of the several recognized formats. See the manual page of pfs-
       inppm to get a list of available formats.

       To write images to standard output use a single dash '-' instead of filename.

       Each file name can contain a %d pattern, which is substituted with frame numbers. The pattern has the same syntax as C printf command.  For
       example, 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.

       --srgb, -s
	      Apply  the  sRGB non-linearity (approximately 2.2 gamma) before writing a file. This can be used instead of using pfsgamma -g 2.2 to
	      store the result of some tone-mapping operators. The option will compress contrast to make sure that tone values are properly  shown
	      on a display. It should be only used with linearized (not gamma corrected) images that are normalized to the 0-1 range.

       --bit-depth <val>, -b <val>
	      Enforce  bit-depth  (per	color  channel).  The allowed values are from 8 to 32. If not specified, the bit depth from the pfs stream
	      ('BITDEPTH' tag) will be used instead. If the 'BITDEPTH' tag is missing, the ImageMagick default value will be  used  (usually  16).
	      The bit depth of actually stored file may be lower of that specified, if the file format does not support higher bit depths.

EXAMPLES

	pfsin memorial.tiff | pfsoutrgbe memorial.hdr
	      Converts from one HDR format to another

       pfsin test.jpg | pfsout test.png
	      Convert from one image format to another.

	pfsin --linear test.jpg | pfsout --srgb test.png
	      The same as above, but apply inverse gamma correction after reading an image (--linear) and then apply gamma correction before writ-
	      ing an image (--srgb).

BUGS

       Writing TIFF files with pfsouttiff seems to be broken, but pfsoutimgmagick can be used instead. pfsout will attempt to use  pfsoutimgmagick
       and fall back to pfsouttiff if pfstools were not compiled with ImageMagick.

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.
