主题：gdi+ 坐标原点可不可以从右下角开始？

 统一为800，就不帮你做了；右下角的，参考下面代码

Dim img As Image = getimage("d:\test.jpg")
Dim g As Graphics = Graphics.FromImage(img)
Dim fnt As New Font("宋体",16)
Dim msg As String = "I Like Foxtable"
Dim sz As Object = g.MeasureString(msg, fnt)
g.DrawString(msg,fnt,Brushes.Red, img.Width - sz.Width - 10, Img.Height - sz.Height - 10)
img.Save("d:\test.jpg")
g.Dispose()
