-u

Update mode

--format FILEFORMAT

Specify output file format (default: guess from extension)

Specify the number of output image channels.

--chnames CHANNELNAMES

Rename channels (comma-separated)

-d TYPE

Set the output data format to one of: uint8, sint8, uint16, sint16, half, float

--tile WIDTH HEIGHT

Specify tile size

--separate

Use planarconfig separate (default: contiguous)

--compression NAME

Set the compression method (default = zip, if possible)

--fovcot FOVCAT

Override the frame aspect ratio. Default is width/height.

--wrap WRAP

Specify wrap mode (black, clamp, periodic, mirror)

--swrap WRAP

Specific s wrap mode separately

--twrap WRAP

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 FILTERNAME

Select filter for resizing (choices: box triangle gaussian sharp-gaussian catmull-rom blackman-harris sinc lanczos3 radial-lanczos3 nuke-lanczos6 mitchell bspline disk cubic keys simon rifman, default=box)

--hicomp

Compress HDR range before resize, expand after.

--sharpen SHARPEN

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 STRATEGY

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 --MNDC %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f %f Set the NDC matrix

--prman-metadata

Add prman specific metadata

--attrib NAME VALUE

Sets metadata attribute (name, value)

--sattrib NAME VALUE

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 FILENAME

Specify an individual MIP level

--cdf

Store the forward and inverse Gaussian CDF as a lookup-table. The variance is set by cdfsigma (1/6 by default), and the number of buckets               in the lookup table is determined by cdfbits (8 bit - 256 buckets by default)

--cdfsigma N

Specify the Gaussian sigma parameter when writing the forward and inverse Gaussian CDF data. The default vale is 1/6 (0.1667)

--cdfbits N

Specify the number of bits used to store the forward and inverse Gaussian CDF. The default value is 8 bits

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

--bumpslopes

Create a 6 channels bump-map with height, derivatives and square derivatives from an height or a normal map

--uvslopes_scale VALUE

If specified, compute derivatives for --bumpslopes in UV space rather than in texel space and divide them by a scale factor. 0=disable by default, only valid for height maps.

--bumpformat NAME

Specify the interpretation of a 3-channel input image for --bumpslopes: "height", "normal" or "auto" (default).

--handed STRING

Specify the handedness of a vector or normal map: "left", "right", or "" (default).

Color Management Options (OpenColorIO enabled)

--colorconfig FILENAME

Explicitly specify an OCIO configuration file

--colorconvert IN OUT

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: sRGB - Display, Display P3 - Display, Rec.1886 Rec.709 - Display, Rec.2100-PQ - Display, ST2084-P3-D65 - Display, P3-D65 - Display, ACES2065-1, ACEScc, ACEScct, ACEScg, sRGB Encoded Rec.709 (sRGB), Gamma 1.8 Encoded Rec.709, Gamma 2.2 Encoded Rec.709, Gamma 2.4 Encoded Rec.709, sRGB Encoded P3-D65, Gamma 2.2 Encoded AdobeRGB, sRGB Encoded AP1, Gamma 2.2 Encoded AP1, Linear Rec.709 (sRGB), Linear P3-D65, Linear AdobeRGB, Linear Rec.2020, Raw)

--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.
