+.P
+.SH NAME
+opj_decompress \- 
+This program reads in a jpeg2000 image and converts it to another 
+image type. It is part of the OpenJPEG library.
+.SP
+Valid input image extensions are
+.B .j2k, .jp2, .j2c, .jpt
+.SP
+Valid output image extensions are
+.B .bmp, .pgm, .pgx, .png, .pnm, .ppm, .raw, .tga, .tif \fR. For PNG resp. TIF it needs libpng resp. libtiff .

+.SH OPTIONS
+.TP
+.B \-\^i "name"
+(jpeg2000 input file name)
+.TP
+.B \-\^l "n"
+n is the maximum number of quality layers to decode. See LAYERS below)
+.TP
+.B \-\^o "name"
+(output file name with extension)
+.TP
+.B \-\^r "n"
+(n is the highest resolution level to be discarded. See REDUCTION below)
+.TP
+.B \-\^x "name"
+(use name as index file and fill it)
+.TP
+.B \-\^ImgDir "directory_name"
+(directory containing input files)

+.P
+.SH JPIP OPTIONS
+Options usable only if the library has been compiled with
+.B BUILD_JPIP
+.TP
+.B -jpip
+Embed index table box into the output JP2 file (compulsory for JPIP)
+.TP
+.B -TP R
+Partition a tile into tile parts of different resolution levels (compulsory for JPT-stream)
+.P
+.SH JPWL OPTIONS
+Options usable only if the library has been compiled with
+.B BUILD_JPWL
+.TP
+.B -W c\fR[=Nc] (Nc is the  number of expected components in the codestream; default:3)
+.TP
+.B -W t\fR[=Nt] (Nt is the maximum number of tiles in the codestream; default:8192)
+.TP
+.B -W c\fR[=Nc]\fB, t\fR[=Nt] \fR(same as above)
+.P
+.SH REDUCTION
+Set the number of highest resolution levels to be discarded.
+The image resolution is effectively divided by 2 to the power of the number of discarded levels. The reduce factor is limited by the smallest total number of decomposition levels among tiles.
+.SH TILES
+Set the maximum number of quality layers to decode. If there are less quality layers than the specified number, all the quality layers are decoded.
