When creating a VT Pro-e project, you can elect to compress and reduce the image
size in the “Page Properties” window for the entire page, and/or perform the same
function of reducing the image size using the “Image Properties” window. A
reduction in image size will save a considerable amount of memory space for your
project.
In VT Pro-e, the Compress checkbox permits the image to be compressed when
compiling. The 16 Bits checkbox converts a 24-bit or 32-bit image to 16 bits. This
conversion to a 16-bit image may cause the loss of some subtle shading. To
compensate for this, use the dithering to simulate the original shading. Various
dithering types are available. Refer to the following illustrations.

MultiByte International Characters
Most languages use a single byte of 8 bits to represent a character, e.g. English,
French, German, Hebrew, Russian, Thai, etc.
Multibyte character fonts require more than the usual 8 bits to specify a character.
This occurs when a language has more than 256 characters (2
8
) in a font. For
example, Chinese fonts contain several thousand characters. Other multibyte
languages include Japanese and Korean.
