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

) in a font. For

example, Chinese fonts contain several thousand characters. Other multibyte

languages include Japanese and Korean.
