- imgareatlx=x
- Set the x-coordinate of the top-left corner of the image area to x.
- imgareatly=y
- Set the y-coordinate of the top-left corner of the image area to y.
- tilegrdtlx=x
- Set the x-coordinate of the top-left corner of the tiling grid to x.
- tilegrdtly=y
- Set the y-coordinate of the top-left corner of the tiling grid to y.
- tilewidth=w
- Set the nominal tile width to w.
- tileheight=h
- Set the nominal tile height to h.
- prcwidth=w
- Set the precinct width to w. The argument w must be an integer power of two. The default
- value is 32768.
- prcheight=h
- Set the precinct height to h. The argument h must be an integer power of two. The default
- value is 32768.
- cblkwidth=w
- Set the nominal code block width to w. The argument w must be an integer power of two.
- The default value is 64.
- cblkheight=h
- Set the nominal code block height to h. The argument h must be an integer power of two.
- The default value is 64.
- mode=m
- Set the coding mode to m. The argument m must have one of the following values:
- int : integer mode
- real : real mode
- If lossless coding is desired, the integer mode must be used. By default, the integer mode
- is employed. The choice of mode also determines which multicomponent and wavelet transforms
- (if any) are employed.
- rate=r
- Specify the target rate. The argument r is a positive real number. Since a rate of one
- corresponds to no compression, one should never need to explicitly specify a rate greater
- than one. By default, the target rate is considered to be infinite.
- ilyrrates=r0[,r1,. . . ,rN
- Specify the rates for any intermediate layers. The argument to this option is a comma
- separated list of N rates. Each rate is a positive real number. The rates must increase
- monotonically. The last rate in the list should be less than or equal to the overall rate
- (as specified with the rate option).
- prg=p
- Set the progression order to p. The argument p must have one of the following values:
- lrcp : layer-resolution-component-position (LRCP) progressive (i.e., rate scalable)
- rlcp : resolution-layer-component-position (RLCP) progressive (i.e., resolution scalable)
- rpcl : resolution-position-component-layer (RPCL) progressive
- pcrl : position-component-resolution-layer (PCRL) progressive
- cprl : component-position-resolution-layer (CPRL) progressive
- By default, LRCP progressive ordering is employed. Note that the RPCL and PCRL
- progressions are not valid for all possible image geometries. (See [4] for more details.)
- nomct
- Disallow the use of any multicomponent transform.
- numrlvls=n
- Set the number of resolution levels to n. The argument n must be an integer that is
- greater than or equal to one. The default value is 6.
- sop
- Generate SOP marker segments.
- eph
- Generate EPH marker segments.
- lazy
- Enable lazy coding mode (a.k.a. arithmetic coding bypass).
- termall
- Terminate all coding passes.
- segsym
- Use segmentation symbols.
- vcausal
- Use vertically stripe causal contexts.
- pterm
- Use predictable termination.
- resetprob
- Reset the probability models after each coding pass.
- numgbits=n
- Set the number of guard bits to n.
