InputJPEG

Module used for reading an image (or sequences of images) from a JPEG file or a sequence of JPEG files. The files can be either gray-scale or RGB.

Example XML definition

Read a single file once

  <module
      class = "InputJPEG"
      name = "IN"
      filename = "image.jpg"
  />

Read a sequence of three files ten times (e. g. image00.jpg, image01.jpg, image02.jpg)

  <module
      class = "InputJPEG"
      name = "IN"
      filename = "image%02d.jpg"
      filecount = "3"
      iterations = "10"
  />

Name	Description	Type	Default
class	The class name for the module; must be "InputJPEG".	string
name	The name of this instance of the module.	string
filename	File to read the image from. If a sequence will be produced %d must be included in the name. It will be replaced with the sequence number of each file. Standard C formats can be used, e. g. %02d will insert the number with two figures and an initial '0'.	string
filecount	Number of files to read	int	1
iterations	Number of times to read the image(s)	int	inf
read_once	Makes the module only read each JPEG image once.	bool	yes

Name	Description
INTENSITY	The intensity of the image.
RED	The red channel of the image (or intensity for a gray image)
GREEN	The green channel of the image (or intensity for a gray image)
BLUE	The blue channel of the image (or intensity for a gray image)

The module calculates the intensity as the average of the R, G, and B channels incorrectly.

This software is based in part on the work of the Independent JPEG Group.
