Create transparent bitmap, draw text to the bitmap, draw bitmap. Second step
is illustrated by the code below.
Jan Slodicka
static void DrawTextToBitmap( BmpRsrcType* result, const char* text, UInt16
len )
{
Err error;
WinHandle oldWinH = WinGetDrawWindow();
WinHandle winH = WinCreateBitmapWindow( (BitmapPtr)result, &error );
if( winH != NULL )
{
WinSetDrawWindow( winH );
WinSetForeColor( 1 ) ;
WinSetBackColor( 0 ) ;
WinDrawChars( text, len, 0, 0 );
WinSetDrawWindow( oldWinH );
WinDeleteWindow( winH, false );
BmpRsrcSetFlag( result, kHasTransparencyFlag, true );
}
}
