Question

我正在尝试使用renderscript执行以下操作： -将图像从YUV转换为灰度（在我的代码中称为root的脚本） -做一些图像处理 -输出最终图像（在我的代码中称为输出的脚本）我能够做到第一步。但是，当我要输出最终图像时（稍后将进行图像处理），该代码不想编译。这是我的renderScript代码：

using (PaintingDB DB = new PaintingDB()) {

    int YearOfWork = 0;
    int.TryParse(ddlYear.SelectedValue, out Year);

                               //  ireader
    trPaintings.DataSource = DB.Museums_GetPaintings(Musea.ID); 


    // ? trPainting.Comparer = new DataReaderComparer("year",DataReaderType.Integer);
    trPaintings.DataBind()

我的Java代码：

uchar4 __attribute__((kernel)) root(uint32_t x, uint32_t y) {
    oldX = x;
    oldY = y;
    x*=3;
    y*=3;
    if (x < 480) {
        x += 2*(479-x);
    } else {
        x -= 2*(x-479);
    }
    pos = 0;
    yValue = 0;
    for (int i = -1; i <= 1; i++) {
       for (int j = -1; j <= 1; j++) {
           index[pos] = (x+i) * height + (y+j);
           yValue += (float) rsGetElementAt_uchar(yuvIn, index[pos]);
           pos += 1;
       }
    }
    yValue = (float) yValue / pos;
    tImgIndex = oldX * 426 + oldY;
    if (yValue > thresholdValue || y == 426*3) {
       out = (uchar4) {255, 255, 255, 255};
       tImg[tImgIndex] = 1;
    } else {
        out = (uchar4) {0, 0, 0, 255};
        tImg[tImgIndex] = 0;
    }
    return out;
     //rsDebug("called root", rsUptimeMillis());
}

uchar4 __attribute__((kernel)) output(uint32_t x, uint32_t y) {
    out = (uchar4) {0, 0, 0, 255};
    if (tImg[x*426+y] == 0) {
        out = (uchar4) {0, 0, 0, 255};
    } else if (tImg[x*426+y] == 1){
        out = (uchar4) {255, 255, 255, 255};
    } else {
        out = (uchar4) {0, 255, 0, 255};
    }
    return out;
     //rsDebug("called root", rsUptimeMillis());
}

渲染脚本以1个代码执行到脚本
