NAME
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.
