LBitmapSettings::SetUserMatchTable

#include "ltwrappr.h"

static L_UINT * LBitmapSettings::SetUserMatchTable(pTable)

L_UINT * pTable;

/* pointer to the table */

Selects a table that speeds conversion when using a palette that you create.

Parameter	Description
pTable	The pointer to the table.

Returns

The pointer to the previous table.

Comments

This function is used with other functions in the following sequence:

1.	Call LBitmapSettings::CreateUserMatchTable to create the table.
2.	Call LBitmapSettings::SetUserMatchTable to make this the current table. (Having this as a separate function allows you to save tables in files and get the one you need, without creating it again.)
3.	Call LBitmapBase::ColorRes with the CRF_USERPALETTE and CRF_FASTMATCHPALETTE options.
4.	Call LBitmapSettings::FreeUserMatchTable when the table is no longer needed.

The completed table occupies 64K bytes of memory. Creation of the table is a slow, memory-intensive process that is useful only if you are using your own palette more than once. For example, you may want to create the table once, save it to a file, and ship that file with your application.
