DNG2JPG v IrfanView

Používám foťák Canon A630 s firmwarem CHDK, díky kterému mohu fotit i do RAWu. I pouhá mechanická konverze těchto RAWů do JPG vytvoří kvalitnější výsledek než JPG přímo z foťáku. Chtěl jsem, aby se mi tahle mechanická činnost provedla co nejjednodušeji. Výsledek je použití dávkového souboru a IrfanView s pluginy:

rem convert STARTTIME and ENDTIME to centiseconds
set /A STARTTIME=(1%STARTTIME:~0,2%-100)*360000 + (1%STARTTIME:~3,2%-100)*6000 + (1%STARTTIME:~6,2%-100)*100 + (1%STARTTIME:~9,2%-100)

rem calculating the duratyion is easy

rem we might have measured the time inbetween days
if %ENDTIME% LSS %STARTTIME% set set /A DURATION=%STARTTIME%-%ENDTIME%

set /A DURATIONH=%DURATION% / 360000
