关于DrawText的问题 (50分)

我画出的文字有时需要左中、中中、中下等对齐方式。<br>如果是单行还行，但如果是多行就不行了，如何解决多行纵向居中？？<br>另外单行中下对齐不行<br>中下对齐：<br>&nbsp; &nbsp;DrawText(XCV.Handle,PChar(Text),Length(Text),R,<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; DT_SINGLELINE or<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; DT_BOTTOM or<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; DT_VCENTER or<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; DT_WORDBREAK);<br>以上不能中下对齐（单行文字）。如何解决？<br>分不够可以加，要多少都行！<br><br>

定义<br>var<br>XCV : TMetafileCanvas;<br>R : Rect;<br>

你写错了[]<br>左中： DT_LEFT or DT_VCENTER<br>中中： DT_CENTER or DT_VCENTER<br>中下： DT_CENTER or DT_BOTTOM

多行居中呢，如何解决？

命苦啊！<br>自己写组件吧，TGraphicControl 。

时间来不及了<br>帮帮忙啊，很急！

多行把 DT_SINGLELINE 去掉就可以了<br>但多行时 DT_BOTTOM、DT_VCENTER、DT_TOP 无效<br>只能自己根据行数计算坐标来设定Rect最终达到目的

多人接受答案了。
