Comments
This will be the local display mode setting for the class object and is used when painting the bitmap.
The first parameter specifies which flags are affected, and the second specifies which of those to turn on. The other affected flags are turned off.
Therefore:
To turn a flag on, specify
it in the first parameter and the second.
To turn a flag off, specify
it in the first parameter, but not the second.
For example, the following statement turns on fast painting, turns off dithered painting, and leaves all other flags as they were:
MyBitmapBase::SetDisplayMode( DISPLAYMODE_FASTPAINT | DISPLAYMODE_DITHEREDPAINT, DISPLAYMODE_FASTPAINT );
This will set the display flags for the floater bitmap to the passed values and will create a new paint palette for the bitmap window and the floater.
