NVCOMPRESS(1) General Commands Manual NVCOMPRESS(1)NAME
nvcompress - Compresses the given image and produces a DDS file.
SYNOPSIS
nvcompress [OPTION] INFILE [OUTFILE]
DESCRIPTION
nvcompress is part of the NVIDIA texture toolset. The tool compresses the given infile into a dds file.
INPUT OPTIONS -color
The input image is a color map (default).
-alpha The input image has an alpha channel used for transparency.
-normal
The input image is a normal map.
-tonormal
Convert input to normal map.
-clamp Clamp wrapping mode (default).
-repeat
Repeat wrapping mode.
-nomips
Disable mipmap generation.
COMPRESSION OPTIONS -fast Fast compression.
-nocuda
Do not use cuda compressor.
-rgb RGBA format
-bc1 BC1 format (DXT1)
-bc1n BC1 normal map format (DXT1nm)
-bc1a BC1 format with binary alpha (DXT1a)
-bc2 BC2 format (DXT3)
-bc3 BC3 format (DXT5)
-bc3n BC3 normal map format (DXT5nm)
-bc4 BC4 format (ATI1)
-bc5 BC5 format (3Dc/ATI2)

maketx - convert images to tiled, MIP-mapped textures
SYNOPSIS
maketx [options] files...
DESCRIPTION
The maketx program will read an image (from any file format for which an ImageInput plugin can be found) and then write it in a form in
which it will have high performance when used by TextureSystem. This involves converting it to tiled (versus scanline) orientation, writing
multiple subimages at different resolutions (MIP-map), and setting a variety of header or metadata fields appropriately for texture maps.
The maketx utility is invoked as follows:
maketx [options] input... -o output
Where input and output name the input image and desired output filename. The input files may be of any image format recognized by OpenIm-
ageIO (i.e., for which ImageInput plugins are available). The file format of the output image will be inferred from the file extension of
the output filename (e.g., "foo.tif" will write a TIFF file).
For a complete description, see /usr/share/doc/libopenimageio-dev/openimageio.pdf.gz.
OPTIONS --help Print help message
-v Verbose status messages
-o %s Output filename
--threads %d
Number of threads (default 0 == #cores)
-u Update mode
--format %s
Specify output file format (default: guess from extension)
--nchannels %d
Specify the number of output image channels.
-d %s Set the output data format to one of:
uint8, sint8, uint16, sint16, half, float
--tile %d %d
Specify tile size
--separate
Use planarconfig separate (default: contiguous)
--fov %f
Field of view for envcube/shadcube/twofish
--fovcot %f
Override the frame aspect ratio. Default is width/height.
--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 (default: box)
(choices: box triangle gaussian catrom blackman-harris sinc lanczos3 radial-lanczos3 mitchell bspline disk)
--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)
--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 camera matrix
--hash Embed SHA-1 hash of pixels in the header
--prman-metadata
Add prman specific metadata
--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
--stats
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
--envcube
Create cubic env map (file order: px, nx, py, ny, pz, nz) (UNIMP)
Color Management Options (OpenColorIO DISABLED)
--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, and constant-color optimizations.
