| .SH NAME |
| im_LabQ2disp, im_LabQ2disp_build_table, im_LabQ2disp_table \- convert LabQ to display rgb quickly and badly |
| .SH 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 ); |
| |
| .SH 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. |
| |
| .SH RETURN VALUE |
| The functions return 0 on success and -1 on error. |
