NAME
       pfsinimgmagick - Load images or frames using ImageMagick++ library

SYNOPSIS
       pfsinimgmagick (<file> [--linear] [--absolute <max_lum>] [--frames <range>] [--skip-missing])  [<file>...]

DESCRIPTION
       This  command  can  load  images or frames in the multitude of image formats supported by the ImageMagick library. This includes but is not
       limited to: BMP, JPG, PNG, GIF, EPS, TIFF, DPX. See the manual page of ImageMagick for the full list of available formats.

       pfsinimgmagick reads images or frames from files 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.

       The  output  of	pfsinimgmagick	is scaled to 0-1 range, unless '--absolute' option is specified. By default, the 'LUMINANCE' tag is set to
       'DISPLAY' contents. Using the '--linear' switch you can force the inverse sRGB transformation to provide linear	data.  In  this  case  the
       'LUMINANCE' tag is set to 'RELATIVE' contents. '--absolute' switch can be used to convert pixels to absolute luminance values.

       This command handles properly 'alpha' channel (transparency) stored in images.

       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, -l
	      Converts pixel values to linear luminance (XYZ), assuming the sRGB color	space  for  the  input	image.	The  maximum  pixel  value
	      (255,255,255) is mapped to Y=1. LUMINANCE tag is set to RELATIVE.

       --absolute <max_lum>, -a <max_lum>
	      --absolute  converts  pixel values to an absolute linear luminance (XYZ), that is the color space, in which channel Y contains lumi-
	      nance given in cd/m^2. The sRGB color space is assumed for the input image. The maximum  pixel  value  (255,255,255)  is	mapped	to
	      Y=<max_lum>.  <max_lum>  is  typically  set  to  80 [cd/m^2] for a CRT monitor. LUMINANCE tag is set to ABSOLUTE. --absolute process
	      images almost the same as --relative, but additionally it scales all pixels by <max_lum>.

EXAMPLES
       pfsinimgmagick frame%04d.dpx --frames 0:10 | pfsview

	      Read frames from files frame0000.dpx, frame0001.dpx, ..., frame0010.dpx and show them using pfsview.

BUGS
       pfsinimgmagick can not read frames from the Standard Input.
