从笔刷/笔转换为颜色

Question

我正在制作一个绘画程序，PictureBox图形的颜色支持FillShape中的画笔和DrawShape中的钢笔。

如果你有任何解决方案，请告诉我如何转换画笔/钢笔的颜色?所以我还可以使用ColorDialog来自定义颜色

Answer 1

我认为你想要的是能够从颜色创建画笔或笔。在这种情况下，应该这样做:

        'create a brush from a known colour
        Dim brush = New SolidBrush(Color.AliceBlue)
        'create a brush from a user defined colour
        Dim brush2 = New SolidBrush(Color.FromArgb(128, 128, 128))
        'create a pen from a known colour
        Dim pen = New Pen(Color.Red)
        'create a pen from a custom colour
        Dim pen2 = New Pen(Color.FromArgb(0, 128, 255))
        'create a pen from a brush
        Dim pen3 = New Pen(brush)
        'don't forget to dispose of your brushes/pens when finished
        brush.Dispose()
        brush2.Dispose()
        pen.Dispose()
        pen2.Dispose()
        pen3.Dispose()
