INTI Selector...

INTI Selector is a specially designed tool for INTI image png processed image. It helps to compare and select the best image(s) from your serie of scans. It relies on the standard practice of having the reference image on the left and allow to circulate images on the right. Once a better image is found, it can be transferred as the new prefered image. Using mouse to zoom and drag allows a more confirtable assessment. A list of best images can be built in case you have multiple best images.
