我在繪制文本的時候，將二元光柵模式設定為R2_NOTXORPEN，但是沒有效果，求大神指點，謝謝
uj5u.com熱心網友回復：
SetROP2 注釋中有這樣的說明Remarks
The drawing mode specifies how the colors of the pen and the interior of filled objects are combined with the color already on the display surface.
The drawing mode is for raster devices only; it does not apply to vector devices. Drawing modes are binary raster-operation codes representing all possible Boolean combinations of two variables, using the binary operators AND, OR, and XOR (exclusive OR), and the unary operation NOT.
