Saving nonlinear calibration info into a compressed PNG or with no image data

[ferencr]

I need to save nonlinear calibration info into the flash memory of a camera. The flash memory available is limited. Fortunately saving a monochrome compressed PNG image is well within the available space.

However, IMAQ Write Image And Vision Info File 2 saves only uncompressed PNGs. Is there a way to save compressed or without image data?

Does the newest version of Vision save any differently?

Thanks ahead for your reply,

Ferenc

I've solved the problem myself.

Under the Calibration Learn Setup for the IMAQ Learn Calibration Template VI I had Learn Error Map and Learn Correction Table set as true. This increased the file size from 240kB to 84Mb.
