图片框循环时在DO中线程超时 [英] Thread time out in DO while loop of a picturebox

问题描述

我使用do while循环来打印图片框中图片的RGB值.如果我使用大尺寸图片，则它为小图片高度和宽度打印RGB值.它没有响应或线程时间不足60分钟.给出一些程序代码以打印HIGH宽度和高度的图片RGB值而没有响应或快速...我的代码是

        listBox1.Items.Add("Pixel             Color")
        Try 
            Dim img As Bitmap = New Bitmap(pictureBox1.Image)
            Dim c As Color
            Dim i As Integer = 0
            Do While (i < img.Width)
                Dim j As Integer = 0
                Do While (j < img.Height)
                    c = img.GetPixel(i, j)
                    listBox1.Items.Add((i.ToString + (","  _
                                    + (j.ToString + ("             " + c.Name)))))
                    j = (j + 1)
                Loop
                i = (i + 1)
            Loop
        Catch ex As Exception
            MessageBox.Show(ex.Message)
        End Try
    End Sub

推荐答案

我猜你正在杀死列表框

如果您的图片是1024 * 1024，那么您试图将超过100万个项目放入列表框

也许将其放入日志文件会更容易...

I''d guess you''re killing the listbox

If your picture is 1024 * 1024 then you''re trying to put more than 1 million items into a listbox

Perhaps putting it into a logfile would be easier ...
