VB没DIB方法。
但可采用Point 方法
按照长整数,返回在 Form 或 PictureBox 上所指定磅的红-绿-蓝 (RGB) 颜色。
'使用Point方法 , 窗体判色代码:Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
Text1 = X
Text2 = Y
Text3 = Point(X, Y)
Text4 = (Val(Text3) Mod 65536) Mod 256 'Red
Text5 = (Val(Text3) Mod 65536) \ 256 'Green
Text6 = Val(Text3) \ 65536 'Blue
Shape1FillColor = RGB(Val(Text4), Val(Text5), Val(Text6))
End Sub
'PictureBox判色代码:
Private Sub Picture1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
Text1 = X
Text2 = Y
Text3 = Picture1Point(X, Y)
Text4 = (Val(Text3) Mod 65536) Mod 256 'Red
Text5 = (Val(Text3) Mod 65536) \ 256 'Green
Text6 = Val(Text3) \ 65536 'Blue
Shape1FillColor = RGB(Val(Text4), Val(Text5), Val(Text6))
End Sub
private void Form4_Load(object sender, EventArgs e) { //遍历panel1里的控件 foreach (Control c in panel1Controls) { if (c is PictureBox) { PictureBox pic = c as PictureBox; picClick += new EventHandler(pic_Click);//添加点击事件 } } } void pic_Click(object sender, EventArgs e) { panel2ControlsClear();//清空panel2中的控件 PictureBox pic = sender as PictureBox; PictureBox pic2 = new PictureBox (); pic2Image = picImage; pic2SizeMode = picSizeMode; panel2ControlsAdd(pic2);//向panel2添加新建的PictureBox }
PictureBox1Point(x, y),注意x,y的单位是Picture1ScaleMode决定的,要转换为像素,需要使用ScaleX,ScaleY转换,即
x=PictureBox1ScaleX(x, PictureBox1ScaleMode,VBPixels)y=PictureBox1ScaleY(y, PictureBox1ScaleMode,VBPixels)
lColor=PictureBox1Point(x, y)
以上就是关于VB中使用DIB方法,取出图片中各个像素的 RGB值全部的内容,包括:VB中使用DIB方法,取出图片中各个像素的 RGB值、c#,在panel1控件内添加pictureBox控件,请问点击pictureBox怎么取得针对panel1控件的坐标、vb问题:如何可以获取在pictutebox中的一坐标点的颜色信息等相关内容解答,如果想了解更多相关内容,可以关注我们,你们的支持是我们更新的动力!
