Delphi 与 DirectX 之 DelphiX(15): TPictureCollectionItem.DrawWaveX、DrawWaveY ...

为什么80%的码农都做不了架构师？>>>

此类函数有:TPictureCollectionItem.DrawWaveX();
TPictureCollectionItem.DrawWaveXAdd();
TPictureCollectionItem.DrawWaveXAlpha();
TPictureCollectionItem.DrawWaveXSub();
TPictureCollectionItem.DrawWaveY();
TPictureCollectionItem.DrawWaveYAdd();
TPictureCollectionItem.DrawWaveYAlpha();
TPictureCollectionItem.DrawWaveYSub();

本例仅使用了 DrawWaveX、DrawWaveY, 效果图:
