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 program 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 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.
- --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.
