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 eight bits to represent a character, e.g. English, 
French, German, Hebrew, Russian, Thai, etc. 
Multibyte character fonts require more than the usual eight bits to specify a 
character. This occurs when a language has more than 256 characters (2
8
) in a font.
