如何更改位图的颜色? [英] How to change the color of bitmap?

问题描述

我的位图的颜色是黑色，我想将其更改为白色.
我已经经历了以下无法更改颜色的练习.

The color of my bitmap is black and i want to change it to white.
I had already gone through following practices which could not able to change the color.

/*Dim oColor As System.Drawing.Color
        oColor = Color.White
      oBitmap.SetPixel(1, 1, oColor)

*/

/* oBitmap.SetPixel(10, 10, Color.BlueViolet)*/

所有库都已包含.
有人可以帮我解决这个问题吗?

All libraries are already included.
Can anybody help me to sort out this problem?

到底是什么意思?
更改像素颜色后是否保存了位图?
:)

What do you mean, exactly?
Did you save the bitmap after changing color of the pixel(s)?
