14.1.5 Image Export
Image export is only supported on Ethernet ports. Inspection images are in bitmap (.bmp) format and are the same size as
the current Field of View (FOV) setting. The images represent all the data in a full FOV.
Each exported image is comprised of a header (64 bytes) followed by the image data. All 16- and 32-bit numeric entries are
little endian.
The header includes the following information:
Byte Offset

Note: If FOV's are adjusted so that they are smaller, the bitmaps will also be smaller.
Image Export Sample Application
The iVu installation package has an Image Export sample application that provides a way to save exported images. In a
production environment, you need to write your own application to process exported images, for example to display them
on an HMI or to save them to disk.
