6.1.6 Image Export
Image export is only supported on Ethernet ports. Inspection images are a maximum 752x480 8-bits per pixel grayscale images in Win-
dows BMP format that represent all the data in a full Field of View (FOV).
Each exported image is comprised of a header (64 bytes) followed by the image data (approximately 361K). All 16- and 32-bit numeric
entries are little endian.
The header includes the following information:
Byte Offset

6.1.6 Image Export Sample Application
The iVu Plus BCR installation CD has a Image Export sample application that provides a way to save exported images. In a production
environment, you will need to write your own application to process exported images, for example to display them on an HMI or to save
them to disk.
