Constructor

Declaration [src]
int
vips_dcrawload (
const char* filename,
VipsImage** out,
...
)
Description [src]
Read a RAW camera file using LibRaw.
This loader supports the most RAW formats, including ARW, CR2, CR3, CRW, DNG, NEF, NRW, ORF, PEF, RAF, RAW, RW2, SRW, X3F, and many others.
The loader applies demosaicing and basic processing to produce an RGB or grayscale image suitable for further processing. It attaches XMP and ICC metadata, if present.
The loader will search for embedded, JPEG-encoded thumbnail and preview
images, attaching them as jpeg-thumbnail-data and jpeg-preview-data.
Set half_size to decode at half-size. This can be much faster, though of
course the image is smaller.
Set bit_depth to control the number of bits to decode to. Either 8 or 16,
default 8,
Optional arguments
bitdepth:gint, number of bits to decode tohalf_size:gboolean, decode at half-size.
This constructor is not directly available to language bindings.
