Preview and convert DDS files from the command line (compressed textures and HDR cubemaps).

This only supports a limited range of DDS formats, see here.

npm install preview-dds -g

The CLI options are as follows:

Usage:
  preview-dds file [opt]

Options:
  --level, -l   optional mipmap level (default 0)
  --face, -f    optional cubemap face to preview (default all)
  --output, -o  write image to stdout (default: not used)
  --quality, -q if output is JPG, encoder quality (0.0 - 1.0)

Preview a cubemap as an unwrapped cross:

preview-dds my-cubemap.dds

Or, preview a single face and mipmap level of the cubemap:

preview-dds my-cubemap.dds --level=1 --face=px

Where face option can be a string like px, py, or pz -- or a number index into the faces array (see cube-face-name).

If no face is specified, all faces are shown together.

You can also use this tool to extract compressed textures and cube faces from a DDS file, by specifying --output=png|jpg.

For example:

preview-dds my-cubemap.dds --output=jpg -q 0.8 -l 2 -f px > cube-face.jpg

The above writes a new file cube-face.jpg with a quality of 0.8, showing mipmap level 2 and the "positive x" face. Result:

The --output flag (or -o) defaults to PNG.
