5.1.6 Image Export
Image export is only supported on Ethernet ports. Inspection images are a maximum 320x240 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 78K). All 16- and 32-bit numeric
entries are little endian.
The header includes the following information:
Byte Offset Field Size in
Bytes
Data Type Description
0-15 Header Prefix 16 char "IVU PLUS IMAGE"
16-19 Header Version 4 UInt32 1
20-23 Image Size 4 UInt32 Number of bytes (Windows BMP image)
24-27 Image Frame Number 4 UInt32 Most recently snapped image frame number
28-29 Image Width 2 UInt16 320 (max)
30-31 Image Height 2 UInt16 240 (max)
32-33 Image Format 2 UInt16 0: Bitmap, 1: JPEG
34-63 Reserved 32 byte Reserved for future use
NOTE: If FOV's are adjusted so that they are smaller, the bitmaps will also be smaller.
5.1.6 Image Export Sample Application
The iVu Plus TG 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.
