djxl_ng - djxl_ng
.SH DESCRIPTION
Warning: This is work in progress, consider using djxl instead!
djxl_ng: JPEG XL decoder
.IP
Flags from ./tools/djxl_ng_main.cc:
.HP
\fB\-allow_more_progressive_steps\fR (allow decoding more progressive steps in
.IP
truncated files. No effect without \fB\-\-allow_partial_files\fR) type: bool
default: false
.HP
\fB\-allow_partial_files\fR (allow decoding of truncated files) type: bool
.IP
default: false
.HP
\fB\-bits_per_sample\fR (0 = original (input) bit depth) type: int32 default: 0
.HP
\fB\-color_space\fR (defaults to original (input) color space) type: string
.IP
default: "RGB_D65_SRG_Rel_Lin"
.HP
\fB\-display_nits\fR (luminance range of the display to which to tone\-map; the
.IP
lower bound can be omitted) type: string default: "0.f\-255."
.HP
\fB\-downsampling\fR (maximum permissible downsampling factor (values greater than
.IP
16 will return the LQIP if available) type: uint32 default: 0
.HP
\fB\-jpeg_quality\fR (JPEG output quality. Setting an output quality implies
.HP
\fB\-\-pixels_to_jpeg\fR.) type: uint32 default: 95
.HP
\fB\-num_reps\fR (How many times to decompress.) type: int64 default: 1
.HP
\fB\-num_threads\fR (Number of worker threads (0 == use machine default).)
.IP
type: int64 default: 0
.HP
\fB\-pixels_to_jpeg\fR (By default, if the input JPEG XL contains a recompressed
.IP
JPEG file, djxl reconstructs the exact original JPEG file. This flag
causes the decoder to instead decode the image to pixels and encode a new
(lossy) JPEG. The output file if provided must be a .jpg or .jpeg file.)
type: bool default: false
.HP
\fB\-preserve_saturation\fR (with \fB\-\-tone_map\fR, how much to favor saturation over
.IP
luminance) type: double default: 0.10000000000000001
.HP
\fB\-print_read_bytes\fR (print total number of decoded bytes) type: bool
.IP
default: false
.HP
\fB\-quiet\fR (silence output (except for errors)) type: bool default: false
.HP
\fB\-tone_map\fR (tone map the image to the luminance range indicated by
.HP
\fB\-\-display_nits\fR instead of performing a naive 0\-1 \-> 0\-1 conversion)
.IP
type: bool default: true
