Sample Application
The iVu Plus BCR installation CD has a Data Export sample application that provides for viewing exported data while
setting up the sensor, etc. In a production environment, you will need to create your own application to process data
exported from the sensor.
2.5 Image Export
Image export is only supported on Ethernet ports. Inspection images are a maximum 752×480 8-bits per pixel grayscale
images in Windows 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
