Options

--help
Print help message
-v
Verbose status messages
-o %s
Output filename
--threads %d
Number of threads (default: #cores)

--format %s
Specify output file format (default: guess from extension)
--nchannels %d
Specify the number of output image channels.
--chnames %s
Rename channels (comma-separated)
-d %s
Set the output data format to one of: uint8, sint8, uint16, sint16, half, float
--tile %d %d
Specify tile size

--wrap %s
Specify wrap mode (black, clamp, periodic, mirror)
--swrap %s
Specific s wrap mode separately
--twrap %s
Specific t wrap mode separately
--resize
Resize textures to power of 2 (default: no)
--noresize
Do not resize textures to power of 2 (deprecated)
--filter %s
Select filter for resizing (choices: box triangle gaussian sharp-gaussian catmull-rom blackman-harris sinc lanczos3 radial-lanczos3 mitchell bspline disk cubic keys simon rifman, default=box)
--hicomp
Compress HDR range before resize, expand after.
--sharpen %f
Sharpen MIP levels (default = 0.0 = no)
--nomipmap
Do not make multiple MIP-map levels
--checknan
Check for NaN/Inf values (abort if found)
--fixnan %s
Attempt to fix NaN/Inf values in the image (options: none, black, box3)
--fullpixels
Set the 'full' image range to be the pixel data window --Mcamera %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f Set the camera matrix --Mscreen %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f Set the screen matrix
--prman-metadata
Add prman specific metadata
--attrib %s %s
Sets metadata attribute (name, value)
--sattrib %s %s
Sets string metadata attribute (name, value)
--sansattrib
Write command line into Software & ImageHistory but remove --sattrib and --attrib options
--constant-color-detect
Create 1-tile textures from constant color inputs
--monochrome-detect
Create 1-channel textures from monochrome inputs
--opaque-detect
Drop alpha channel that is always 1.0
--no-compute-average
Don't compute and store average color
--ignore-unassoc
Ignore unassociated alpha tags in input (don't autoconvert)
--runstats
Print runtime statistics
--mipimage %s
Specify an individual MIP level

Basic modes (default is plain texture):

--shadow
Create shadow map
--envlatl
Create lat/long environment map
--lightprobe
Create lat/long environment map from a light probe

Color Management Options (OpenColorIO enabled)

--colorconvert %s %s
Apply a color space conversion to the image. If the output color space is not the same bit depth as input color space, it is your responsibility to set the data format to the proper bit depth using the -d option. (choices: linear, sRGB, Rec709)
--unpremult
Unpremultiply before color conversion, then premultiply after the color conversion. You'll probably want to use this flag if your image contains an alpha channel.

Configuration Presets

--prman
Use PRMan-safe settings for tile size, planarconfig, and metadata.
--oiio
Use OIIO-optimized settings for tile size, planarconfig, metadata.
