jpeg2stiff - convert a Joint Photographic Experts Group (JPEG) image file to Stream TIFF (STIFF)
As shipped in IRIX 6.5. First release of IRIX 6.5.
NAME jpeg2stiff - convert a Joint Photographic Experts Group (JPEG) image file to Stream TIFF (STIFF) SYNOPSIS jpeg2stiff [-O filename] [-L filename] [-h] [-D] JPEGImageFilename ... DESCRIPTION jpeg2stiff converts Joint Photographic Experts Group (JPEG) image files into Stream TIFF (STIFF) format. jpeg2stiff expects at least one JPEG image file to be specified on the command line after all option switches. By default, jpeg2stiff assumes that its output should be written to the standard output and messages should be written to standard error. The input image file(s) must be in the JPEG File Interchange Format (JFIF). -O filename Specifies the name of the file to which the STIFF output will be sent. If the -O option is not specified, output will be sent to the standard output. -L filename Specifies the name of the file to which error, warning and informational messages are to be written. If the file specified already exists, any messages generated by jpeg2stiff will be appended to the end of the file. If the -L option is not specified, message output will be sent to standard error. -h Prints a program usage message to the standard error. This usage message also lists the currently supported output configurations. -D Specifies verbose output for debugging purposes. NOTES 1. Currently, jpeg2stiff accepts JPEG image data only in the JFIF file format. The TIFF 6.0 JPEG format is not currently supported. 2. jpeg2stiff can decompress baseline and extended sequential JPEG compression methods. Progressive, hierarchical and lossless JPEG methods are not currently supported. 3. jpeg2stiff accepts grayscale and RGB JPEG image colorspaces. A grayscale image will produce a W STIFF image (ST_TYPE_W) and an RGB image will produce an RGB STIFF image (ST_TYPE_RGB). 4. Only input images with eight bits per component are supported at this time. 5. If jpeg2stiff is given an unrecognized or incomplete command line option switch, it will print a warning message to the standard error, ignore the option and continue processing. ACKNOWLEDGEMENTS The jpeg2stiff program uses the JPEG software package provided by the Independent JPEG Group. The Independent JPEG Group's software is available via anonymous ftp from a number of Internet locations.
