摘要： TDirectDrawSurface.Fill(); TDirectDrawSurface.FillRect(); TDirectDrawSurface.FillRectAlpha(); TDirectDrawSurface.FillRectAdd(); TDirectDrawSurface.FillRectSub(); 其中 Fill 在前面每个例子中都有用到; 另外注意: 这几个函数中的... 阅读全文

摘要： 上个例子中 TDirectDrawSurface 是从 TDXImageList 中获取的图片, 其实 TDirectDrawSurface 自己获取图片的方法有很多: TDirectDrawSurface.LoadFromFile(); TDirectDrawSurface.LoadFromStream(); TDirectDrawSurface.LoadFromGraphic(); TDi... 阅读全文

摘要： 前面的绘图命令都是来自 TDXImageList, 准确地说是来自 TDXImageList.Items 所包含的 TPictureCollectionItem 对象. 那 TDXDraw 本身有没有绘图命令呢? TDXDraw 本身没有绘图命令, 但它的有绘图表面(TDirectDrawSurface), 譬如: Surface、Primary; TDXDraw 的绘图表面有更多的绘图命令,... 阅读全文
