PhotoView with Delete&Transfer of matched files, e.g. RAW

Posted on by EskeRahn

This is a plain PhotoViewer with just TWO special function:

The ability to show more EXIF info than most and to delete or transfer matching partner files on request also, according to user defined masks.

E.g. Also handle RAW or cropped variant of a file named with predefined syntax.

PhotoView_Dump

Settings for position, size, splitter positions, last used folders… can be saved in users registry.

Download zip: PhotoView.Zip

Length of round (carpet) roll

Carpet

For some reason, surprisingly few know this extremely simple formula, please share it.

I have actually seen in a carpet store an employee unrolling the carpet to measure the length!!

[The formula is simple to prove too… r=kφ, L=∫r dφ=∫kφ dφ=½k(φ2²-φ1²)=½k(φ2+φ1)×(φ2-φ1)=½(r2+r1) ×n2π=(r2+r1) × nπ , q.e.d.]
