Why pictures have not resolution information when saved in BMP format

In old software, we use DPI section of the image files to save the calibration information. The disadvantage of this method is that images with calibration information become very small when opened by excel.

The new software use a new method without the influence on DPI and the above problem is resolved. But this new method is not supported by BMP format. Please select other format when users want to save images with calibration or measurement information.
