3.3.2 Supported Input Formats

tdlmake supports most of the common formats used in a production environment:
TIFF
tdlmake supports stripped or tiled TIFFs with 1 to 6 channels. Suppported data types are: Unsigned single channel images (grayscale or b&w) can have either MINISBLACK or MINISWHITE photometric. Either way, the output file (`.tdl') will be MINISBLACK. Signed files are required to have either RGB or MINISBLACK photometric. Files with less than 8 bits per sample are promoted to 8 bits per sample in the output. Otherwise, the output format is the same as the input. LogLuv encoded TIFFs are supported and are kept in their LogLuv form when processed. TIFFs with separate planes are not supported.
JPEG
tdlmake supports 8 bit (grayscale) and 24 bit JPEGs.
Radiance Picture Format
Files produced by Radiance(4) are supported. Both XYZE and RGBE encoding modes are recognized by tdlmake. Run-lenght encoded files are also supported. Note that there is a restriction on image orientation: only -Y +X orientation is correctly recognized, any other orientation will be reverted to -Y +X. This is not a major problem though because it can be corrected by using the `-flips' and `-flipt' options (see section 3.3.1 Command Line Options).
OpenEXR
ILM's OpenEXR format is supported by tdlmake with the restriction that images should be in RGB or RGBA format(5).
zfile
zfiles are only used to produce shadow maps.

For cube environment maps (`-envcube'), all six images are required to be of the same file format.
