static L_UINT * LBitmapSettings::SetUserMatchTable(pTable)

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


L_UINT * pTable

The pointer to the table.


The pointer to the previous table.


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.

Required DLLs and Libraries
