When creating a VisionTools 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 VisionTools 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. Check your
image with each of the available dithering types to determine which will deliver the
best quality image.
Dithering type selection can be accessed from the “Page Properties” or “Image
Properties” windows in VT-Pro-e. Refer to the following illustrations.
