在VB中用Paintpicture方法进行图形处理

在控件picture1中放一张源图，在控件picture2上进行图形处理:



1.复制：picture2.paintpicture picture1.picture,0,0,picture2.width,picture.height,0,0, -



picture1.width,picture1.height



2.图形左右倒置：picture2.paintpicture picture1.picture,0,0,picture2.width,picture2.height,picture1.width,0, -



-picture1.width,picture1.height



3.图形上下倒置：picture2.paintpicture picture1.picture,0,0,picture2.width,picture2.height,0, picture1.height,-



picture1.width,- picture1.height
