im_LabQ2disp3
Convert labq to display rgb quickly and badly
Usage
#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 );
Overview
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.
