.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.

||
|
