Method
VipsImagecast
Declaration [src]
int
vips_cast (
VipsImage* in,
VipsImage** out,
VipsBandFormat format,
...
)
Description [src]
Optional arguments:
shift: %gboolean, integer values are shifted
Convert in to format. You can convert between any pair of formats.
Floats are truncated (not rounded). Out of range values are clipped.
Casting from complex to real returns the real part.
If shift is TRUE, integer values are shifted up and down. For example,
casting from unsigned 8 bit to unsigned 16 bit would
shift every value left by 8 bits. The bottom bit is copied into the new
bits, so 255 would become 65535.
