分配给输出paramaeter时的Android渲染脚本错误 [英] Android Render Script Error when assigning to Out paramaeter
本文介绍了分配给输出paramaeter时的Android渲染脚本错误的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我得到误差
Fatal signal 11 (SIGSEGV) at 0x51b71000 (code=1), thread 3696 (sssist.magnitab)
每当我将值分配给出来发回值主应用程序的参数,当我删除分配错误消失了,这是我的code,(下面部分的android code)
Whenever i assign value to out parameter for send back the values main app , when i remove assignment error goes away , here is my code ,(below part the android code )
void root(const char *in, int *out, uint32_t x, uint32_t y) {\
int pixelData[size];
for (int i = 0; i <size ; i += 16)
{
//rsDebug("---------------:","3333");
int lumOne = in[i];
lumOne += 128;
pixelData[lumOne]=pixelData[lumOne]+1;
int lumTwo = in[i+2];
lumTwo += 128;
//pixelData[lumTwo]++;
pixelData[lumTwo]=pixelData[lumTwo]+1;
}
out[10]=23;
}
RenderScript mRS;
mRS = RenderScript.create(activity);
ScriptC_mono mScript;
// Convert to Bitmap
Allocation alloc = Allocation.createSized(mRS, Element.I8(mRS), array.length, Allocation.USAGE_SCRIPT);
alloc.copyFrom(array);
int[] ret = new int[array.length];
int[] ret2 = new int[array.length];
Allocation alloc_out = Allocation.createSized(mRS, Element.I32(mRS), array.length, Allocation.USAGE_SCRIPT);
alloc_out.copyFrom(ret2);
mScript = new ScriptC_mono(mRS, activity.getResources(),R.raw.mono);
mScript.set_size(array.length);
mScript.forEach_root(alloc, alloc_out);
alloc_out.copyTo(ret2);
//byte [] outarray = array;
// mOutPixelsAllocation.copyTo(outarray);
mRS.finish();
帮我纠正。
推荐答案
您应该只写出来[0],并且永远不出来[10]。该出指针自动先进和根()在你的输入/输出分配每个单元上运行。每个单元有此功能输入/输出双指针调用一个有效的,真正映射到[Y] [X],OUT [Y] [X](或1D如适用)。
You should only be writing to out[0], and never to out[10]. The out pointer is advanced automatically and root() is run on each cell in your input/output allocations. Each individual cell has this function called with a valid in/out pointer pair that really maps to in[y][x], out[y][x] (or 1D as appropriate).
