Reset the current draw buffer
void PgClearDrawBuffer( void ); void PgClearDrawBufferCx(void *dc);
ph
These functions reset the current draw buffer without flushing. PgClearDrawBuffer() works on the current draw context, while you can specify the draw context for PgClearDrawBufferCx().
/* * Draw the following group of 3 lines */ PgDrawILine( 100, 100, 200, 300 ); PgDrawILine( 200, 300, 700, 700 ); PgDrawILine( 700, 700, 0, 0 ); PgFlush(); /* * Don't draw the following group of 3 lines */ PgDrawILine( 50, 100, 50, 300 ); PgDrawILine( 300, 20, 30, 700 ); PgDrawILine( 500, 700, 0, 100 ); PgClearDrawBuffer(); PgFlush();
