A very easy question, can you help me please

Sorry for my English, but I have no Chinese IME here.

The problem is how can I show a picture according to a predefined data array?

For example.

short[] pixeldata = {0, 255,
0 255};

height = 2;
width = 2;


then I have a 2*2 picture, which looks like

black white
black white

Thank you

把颜色转换成COLORREF比如0就是RGB(0,0,0),255就是(255,255,255)，然后根据长宽做个循环，用SetPixel输出：
for (int i =0;i<height;i++)
for (int j=0;j<width;j++)
pDC->SetPixel(j,i, RGB(pixeldata[j][i],pixeldata[j][i],pixeldata[j][i]));

Thank you for your replies

I wonder if I can copy the source array directly to the target array,
for example

I get the array as
char[] data = {0,0,0,255,255,255,0,0,0,255,255,255};

And I just copy the source data to the target memory space. If this is possible or not?

Thank you

如果是这样的话，你需要根据BMP的文件格式一点点填充内存；

[ringphone]

CreateCompatibleBitmap，然后把数据SetDIBBits
如果不想创建BMP而直接显示，用DrawDibDraw，但是必须自己填充BITMAPINFO和BITMAOINFOHEADER结构，告诉系统图象大小颜色等信息
