Supported arguments are as follows: .TP .BI INFO= w , h , dpi Create the initial information chunk. Arguments .IR w ", " h ", and " dpi describe the width, height and resolution of the image. All arguments may be omitted. The default resolution is 300 dpi. The default width and height will be retrieved from the first mask chunk specified in the command line options. .TP .BI Sjbz= jb2file Create a .SM JB2 foreground mask chunk. File .I jb2file may contain raw JB2 data, or be a DjVu file containing JB2 data such as those produced by program .BR cjb2 . .TP .BI Smmr= mmrfile Create a .SM MMR/G4 foreground mask chunk. File .I mmrfile may contain raw MMR data or be a DjVu file containing MMR data. .TP .BI BG44= iw44file "[:" n "]" Create one or more .SM IW44 background chunks. File .I iw44file must contain .SM IW44 data. Such files can be obtained by compressing the background image with program .B c44 and extracting the raw .SM IW44 data using program .BR djvuextract . The optional argument .I n indicates the number of chunks to copy from the IW44 file. Omitting the number of chunks copies all available chunks. .TP .BI BGjp= jpegfile Create a .SM JPEG encoded background chunk. File .I jpegfile must contain .SM JPEG encoded data. .TP .BI BG2k= jpegfile Create a .SM JPEG-2000 background chunk. File .I jpegfile must contain .SM JPEG-2000 encoded data. The DjVu decoder does not yet display files containing JPEG-2000 data. .TP .BI FGbz= bzzfile Create a foreground color chunk describing one solid color for each .SM JB2 encoded mark. File .I bzzfile is best created by extracting the chunk data from an existing DjVu file using command .BR djvuextract . .TP .BI FG44= iw44file Create a .SM IW44 foreground color chunk. File .I iw44file must contain .SM IW44 data. Such files can be obtained by compressing the background image with command .B c44 and extracting the raw .SM IW44 data using program .BR djvuextract . Only the first chunk is copied. .TP .BI FGjp= jpegfile Create a .SM JPEG foreground color chunk. .TP .BI FG2k= jpegfile Create a .SM JPEG-2000 foreground color chunk. The DjVu decoder does not yet display files containing JPEG-2000 data. .TP .BI INCL= fileid Create a DjVu3 include chunk pointing to the component file named .IR fileid . The resulting file should then be included into a multipage document using command .BR djvm . .TP .BI PPM= ppmfile Create a .SM IW44 background chunk and a .SM IW44 foreground color chunk by masking and subsampling the .SM PPM file .IR ppmfile. Assume, for instance, that we have a .SM PPM image .B myimage.ppm and an identically sized .SM PBM bitonal image .B mymask.pbm whose black pixels indicate which pixels belong to the foreground. Such a bitonal file might have been obtained by thresholding or color-keying the .SM PPM image. We can then produce a DjVuDocument image using the following two commands: .IP "" 3 .B cjb2 mymask.pbm mymask.djvu .br .B djvumake my.djvu Sjbz=mymask.djvu PPM=myimage.ppm .br .br .PP Please refer to the DjVu specification ( .B http://www.djvuzone.org/djvu/djvu/djvuspec/ ) for more information about the composition of a legal DjVu image file. .SH CREDITS This program was written by L\('eon Bottou and was then improved by Andrei Erofeev , Bill Riemers and many others. .SH SEE ALSO .BR djvu (1), .BR djvuextract (1), .BR cjb2 (1), .BR c44 (1)
