NAME
image_to_j2k - convert a PNM, PGM, PPM, PGX or BMP into a J2K or JP2 file
SYNOPSIS
DESCRIPTION
image_to_j2k converts an image into a JPEG 2000-encoded image
OPTIONS
-ImgDir sourcedir Directory of PGM, PPM, PNM, PGX or BMP files to convert -OutFor extension J2K or JP2 output file format -i source PNM, PGM or PPM file to convert -o destination J2K or JP2 file to output to -h Display help information -cinema2k fps Digital Cinema 2K profile compliant codestream for 2K resolution. 24 or 48 fps. -cinema4k [fps] Digital Cinema 4K profile compliant codestream for 4K resolution. fps default is 24 -r ratios compression factor for successive layers, comma seperated -q psnr psnr for successive layers, comma seperated -n rescount number of resolutions -b blocksize width and height of code block, comma-seperated -c precintsize width and height of precinct, comma-seperated -t tilesize width and height of tile, comma-seperated -p progression progression order, one of LRCP, RLCP, RPCL, PCRL, CPRL -s subsampling subsampling factor in X and Y, comma-seperated. Values larger than 2 can produce errors -POC orders progression order change -SOP write SOP marker before each packet -EPH write EPH marker after each header packet -M modeflags Sum of the values of the modes, as follows: 1. BYPASS (LAZY) 2. RESET 4. RESTART (TERMALL) 8. VSC 16. ERTERM (SEGTERM) 32. SEGMARK (SEGSYM) -x indexfile create an index file -ROI:quantize quantization indices upshifted for component c between 0 and 2 inclusive with an upshift of U between 0 and 37 inclusive -d imageoffset X and Y offset of the origin of the image, comma-seperated -T tileoffset X and Y offset of the origin of the tiles, comma-seperated -I use the irreversible DWT 9-7
EXAMPLE
ratios: 20,10,1 Quality 1: compress 20x; Quality 2: compress 10x; Quality 3: lossless compression psnr: 30,40,50 quantize: c=0,U=25 orders: T1=0,0,1,5,3,CPRL Title 1: Resolution 0 start, component 0 start, layer 1 end, resolution 5 end, component 3 end, CPRL progression
