Introduction to libraw
Libraw is a library for reading RAW files obtained from digital photo cameras (CRW/CR2, NEF, RAF, DNG, and others).

Short Descriptions
4channels
|
generates four TIFF files from RAW data, one file per channel
|
dcraw_half
|
emulates "dcraw -h" (see DCRAW manpage)
|
mem_image
|
emulates "dcraw [-4] [-6] [-e]" (see DCRAW manpage)
|
postprocessing_benchmark
|
creates eight different renderings from one source file. The first and fourth one should be identical
|
simple_dcraw
|
emulates call to "dcraw [-D] [-T] [-v] [-e] [-4]" (see DCRAW manpage)
|
dcraw_emu
|
is an almost complete dcraw emulator (see DCRAW manpage)
|
half_mt
|
emulates call to "dcraw -h [-w] [-a] [-v]" (see DCRAW manpage)
|
multirender_test
|
creates eight different renderings from one source file. The first and fourth one should be identical
|
raw-identify
|
emulates call to "dcraw -i [-v]" (see DCRAW manpage)
|
unprocessed_raw
|
generates unprocessed raw image: with masked pixels and without black subtraction
