源代�?/a>

outfit7公司生��了一�p�d��的会说话的朋友app,最著名的是会说话的汤姆�?
利用业余旉��做了一个TalkingJohn,资源都是用原app�?在xcode4.1�~�译通过.
为CCDirector增加category�Ҏ��屏幕录像,和音视频合成.
录像模式在模拟器�q�行良好,但是在ipad上运行经常录制不成功.
如果有哪位同学改好了�q�个问题,��L��我发邮�gcugdj at hotmail.com.

几天不写�E�序手就有点生，整理了一�D�|��囄��转成ASCII码的�E�序。暂时只支持24位真彩色囄��Q�ASCII码可以自行扩充。大体算法就是把整个位图分成8*16的小块，计算��块的灰度值��d��Q�然后匹配一个灰度值接�q�的字符。具体算法细节可以参考网上资料�?br>�E�序源代码可以在�q�里下蝲�?br>

Bill Gates: Never surrender to complexity

��四 — Tue, 15 Jan 2008 02:04:00 GMT

The barrier to change is not too little caring; it is too much complexity.

To turn caring into action, we need to see a problem, see a solution, and see the impact. But complexity blocks all three steps.

If we can really see a problem, which is the first step, we come to the second step: cutting through the complexity to find a solution.

Cutting through complexity to find a solution runs through four predictable stages: determine a goal, find the highest-leverage approach, discover the ideal technology for that approach, and in the meantime, make the smartest application of the technology that you already have �?whether it's something sophisticated, like a drug, or something simpler, like a bednet.

The final step – after seeing the problem and finding an approach – is to measure the impact of your work and share your successes and failures so that others learn from your efforts.

But if you want to inspire people to participate, you have to show more than numbers; you have to convey the human impact of the work – so people can feel what saving a life means to the families affected.

GDI+的颜色矩�는�一�?*5的float型数�l�构成，用来�Ҏ��一个像素的颜色(R,G,B,A)做线性变换，每个像素颜色与矩�늛�乘。把一�q�彩色图转成灰度囄��法是，假设像素炚w��色�ؓ(r,g,b)�Q��{换成灰度图三个颜色分量是一��L��Q�称作灰�Ӟ��灰阶的计��是 r*0.299+g*0.587+b*0.114。我们可以逐个像素转换�Q�也可以使用颜色矩阵。所以彩色图转灰度图的颜色矩阵�ؓ
ColorMatrix matrix =
{0.299, 0.299, 0.299, 0, 0,
0.587, 0.587, 0.587, 0, 0,
0.114, 0.114, 0.114, 0, 0,
0, 0, 0, 1, 0,
0, 0, 0, 0, 0}

�q�样转换后，灰度囄��灰阶分布�?~255之间。如果想把一�q�彩色图渲染成双色图�Q�定义一个深颜色darker�Q�一个浅颜色lighter,那么灰度囑֏�是一个darker是黑色而lighter是白色的特例。本来分布在0~255的灰�Ӟ��q�样应该分别分布�?lighter.r~darker.r),(lighter.g~darker.g),(lighter.b~darker.b)�?/p>

�~�写代码如下�Q��用白色和紫色�?/p>

void CDuotoneDlg::OnButton1()
{
    Bitmap  img(L"c:\\test1.jpg");
    Graphics graphix(this->GetDC()->m_hDC);

    Color darker(0);
    Color lighter(8414370);

    const float gray_r = 0.299f;
    const float gray_g = 0.587f;
    const float gray_b = 0.114f;

    float offset_r = (float)darker.GetR() / 255;
    float offset_g = (float)darker.GetG() / 255;
    float offset_b = (float)darker.GetB() / 255;

    float r = (float)(lighter.GetR() - darker.GetR()) / 255;
    float g = (float)(lighter.GetG() - darker.GetG()) / 255;
    float b = (float)(lighter.GetB() - darker.GetB()) / 255;

    ImageAttributes imgatt;
    ColorMatrix matrix =
        {
           gray_r*r, gray_r*g, gray_r*b, 0, 0,
           gray_g*r, gray_g*g, gray_g*b, 0, 0,
           gray_b*r, gray_b*g, gray_b*b, 0, 0,
           0, 0, 0, 1, 0,
           offset_r, offset_g, offset_b, 0, 1
        };

    imgatt.SetColorMatrix(&matrix, ColorMatrixFlagsDefault, ColorAdjustTypeBitmap);

    int iWidth = img.GetWidth();
    int iHeight = img.GetHeight();

    graphix.DrawImage(
        &img,
        Rect(0, 0, iWidth, iHeight),
        0.0f,
        0.0f,
        iWidth,
        iHeight,
        UnitPixel,
        &imgatt);

    graphix.ReleaseHDC(this->GetDC()->m_hDC);
}
