im_LabQ2disp(3) im_LabQ2disp(3)
NAME
im_LabQ2disp, im_LabQ2disp_build_table, im_LabQ2disp_table - convert
LabQ to display rgb quickly and badly
SYNOPSIS
#include <vips/vips.h>
int im_LabQ2disp( IMAGE *in, IMAGE *out, struct im_col_display *d );
void *im_LabQ2disp_build_table( IMAGE *out, struct im_col_display *d );
int im_LabQ2disp_table( IMAGE *in, IMAGE *out, void *table );
DESCRIPTION
These functions convert LabQ images to displayable RGB as quickly as
possible.
im_LabQ2disp() converts in to out using the display profile d. It has
to build a large lookup table, so takes a while to start.
im_LabQ2disp_build_table() is just the table-build phase of
im_LabQ2disp(). It returns a handle to the built table (or NULL for
error). The memory for the table is allocated local to out (ie is freed
when out is closed).
im_LabQ2disp_table() converts in to out using the supplied table.
RETURN VALUE
The functions return 0 on success and -1 on error.
