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 OpenImageIO (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/openimageio-doc/openimageio.pdf.gz.

       --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

       --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

       --ignore-unassoc
              Ignore unassociated alpha tags in input (don't autoconvert)

       --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

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

   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.
