What it does

The cameras on the bench

InfiRay .irg files, Hikmicro JPEGs, FLIR R-JPEG and AFF .img files, and DJI R-JPEGs, each detected from the bytes.

Measure, not just look

Click to place named spot readings, read the pixel under the pointer, and see the hottest and coldest points marked live.

Recalibrate

For FLIR files, change emissivity, distance, reflected and air temperature and humidity, and every pixel is computed again.

Export the evidence

Nine palettes with histogram equalisation, and a PNG with every marker and label on it, from the window or the command line.
