-r top left height width

Specifies the rectangle for region decode

-T m

Reduced resolution (mipmap) decode 0: Full resolution (default) 1: 1/2 res (down-sampled from full res) 2: 1/4 res (native decode) 3: 1/8 res (down-sampled from 1/4 res) 4: 1/16 res (native decode)

>4: 1/(2^m) res (down-sampled from 1/16 res)

-O orientation

0: No transformation (default) 1: Flip vertically 2: Flip horizontally 3: Flip vertically & horizontally 4: Rotate 90 degrees CW 5: Rotate 90 degrees CW & flip vertically 6: Rotate 90 degrees CW & flip horizontally 7: Rotate 90 degrees CW & flip vert & horiz

-s skip subbands

Used for compressed domain transcoding 0: All subbands included (default) 1: Skip flexbits 2: Skip highpass 3: Skip highpass & lowpass (DC only)

-a alpha decode

0: Decode without alpha channel 1: Decode only alpha channel 2: Decode image & alpha (default)

-p strength

Post processing filter strength 0: None (default) 1: Light 2: Medium 3: Strong 4: Very strong

-C

Suppress overlapping boundary macro blocks (Used for compressed domain tile extraction)

-t

Display timing information

-v

Display verbose decoder information

Eg: JxrDecApp -i input.jxr -o output.bmp -c 0
