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
       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, -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
              luminance 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.
