YUV Files 635
There are several classes of TIFF files, e ach varying
in the color depth and color palette that they
support.
You can render TIFF files with alpha, luminance
(page 3–964),andUVcolorcoordinate
information, which describes illuminance (page
3–955).Youalsohavetheoptiontorendera
compressed im age. Luminance and illuminance
data are rendered by the Lighting Data Exporter
utility (page 3–303).

When you render to a TIFF file, you have the
following options:
Monochrome—Creates an 8-bit grayscale image.
Co lor—Creates a 24-bit color image (no alpha
channel).
ImageTypegroup
Lets you choose the method for saving image
information:
•
8-bit Greysca le—Creates a n 8-bit grayscale
image.
•
8-bit Color—Creates an 8-bit color image.
•
16-bit Color—Creates a 16-bit color image.
•
16-bit S GI LogL—Creates a color image that
includes a logarithmic encoding of the
luminance channel.
•
32-bit SGI LogLUV —Creates a color image
that includes a logarithmic encoding of the
luminance channel and UV color coordinate
information.
Store Alpha Channel—When on, stores the alpha
channel along w ith other image data. Alpha data

Compression Type group
Lets you render a compressed TIFF file.
Default=No Compression.
•
No Compression—Does not compress the
rendered image.
•
Packbit s —Uses the TIFF Packbits algorithm to
compress the file.
Dots Per Inch—Sets the dots p er inch (dpi) for the
saved image. This s etting does not change the
resolution of the final image, but can affect the way
it prints in documen ts.
YUV Files
YUV files are still-image graphics fi les in the
Abekas Digital Disk format.
YUV is supported only as an input file format. You
can use YUV files as general-purpose bitmaps, but
you can’t render to a YU V file.
