7       LabQ to display rgb quickly and badly

SYNOPSIS

10       #include <vips/vips.h>
11       #include <vips/colour.h>

13       int im_LabQ2disp( IMAGE *in, IMAGE *out, struct im_col_display *d );
14
15       void *im_LabQ2disp_build_table( IMAGE *out, struct im_col_display *d );

DESCRIPTION

21       These functions convert LabQ images to displayable RGB  as  quickly  as
22       possible.
23
24       im_LabQ2disp()  converts  in to out using the display profile d. It has
25       to build a large lookup table, so takes a while to start.
26
27       im_LabQ2disp_build_table()   is   just   the   table-build   phase   of
28       im_LabQ2disp().  It  returns  a  handle to the built table (or NULL for
29       error). The memory for the table is allocated local to out (ie is freed
30       when out is closed).
31
32       im_LabQ2disp_table() converts in to out using the supplied table.

RETURN VALUE

36       The functions return 0 on success and -1 on error.
