I am confused as to why I am getting 128 bytes for scan-lines/rowpitch rather than the 8 I am specifying. The BMP in question being loaded is 4 pixels, red top left, green top right, blue bottom left, yellow bottom right.
Code is as follows:
ID3D11Resource *g_pOverlay_Staging = nullptr;
IWICImagingFactory* WICFactory = nullptr;
IWICBitmapDecoder * WICBitmapDecoder = nullptr;
IWICBitmapFrameDecode * WICBitmapFrame = nullptr;
WICPixelFormatGUID pixelFormat;
HR(CoCreateInstance(CLSID_WICImagingFactory, nullptr, CLSCTX_INPROC_SERVER, __uuidof(IWICImagingFactory), (LPVOID*)&WICFactory));
HR(WICFactory->CreateDecoderFromFilename(L"province_map.bmp", nullptr, GENERIC_READ, WICDecodeMetadataCacheOnDemand, &WICBitmapDecoder));
HR(WICBitmapDecoder->GetFrame(0,&WICBitmapFrame));
HR(WICBitmapFrame->GetPixelFormat(&pixelFormat));
DXGI_FORMAT format;
if (pixelFormat == GUID_WICPixelFormat24bppBGR){
std::wostringstream outs2;
outs2 << "pixelformat = GUID_WICPixelFormat24bppBGR" << std::endl;
OutputDebugString(outs2.str().c_str());
format = DXGI_FORMAT_R8G8B8A8_UNORM;
}
IWICFormatConverter * FC = nullptr;
WICFactory->CreateFormatConverter(&FC);
HR(FC->Initialize(WICBitmapFrame, GUID_WICPixelFormat32bppRGBA, WICBitmapDitherTypeErrorDiffusion, 0, 0, WICBitmapPaletteTypeCustom));
std::unique_ptr<uint8_t[]> temp(new uint8_t[16]);
HR(FC->CopyPixels(0, 8, 16, temp.get()));
D3D11_TEXTURE2D_DESC desc;
desc.Width = 2;
desc.Height = 2;
desc.MipLevels = 1;
desc.ArraySize = 1;
desc.Format = format;
desc.SampleDesc.Count = 1;
desc.SampleDesc.Quality = 0;
desc.Usage = D3D11_USAGE_STAGING;
desc.BindFlags = 0;
desc.CPUAccessFlags = D3D11_CPU_ACCESS_WRITE | D3D11_CPU_ACCESS_READ;
desc.MiscFlags = 0;
D3D11_SUBRESOURCE_DATA initData;
initData.pSysMem = temp.get();
initData.SysMemPitch = 8;
initData.SysMemSlicePitch = 16;
ID3D11Texture2D* tex = nullptr;
HR(d3d11DeviceInterface->CreateTexture2D(&desc, &initData, &tex));
g_pOverlay_Staging = tex;
D3D11_MAPPED_SUBRESOURCE mapped_subresource;
HR(d3d11DeviceContextInterface->Map(g_pOverlay_Staging, 0, D3D11_MAP_READ_WRITE, 0, &mapped_subresource));
uint8_t * v = reinterpret_cast<uint8_t*>(mapped_subresource.pData);
unsigned int x = 0;
while (x < 256 ) {
std::bitset<8> one(v[x]);
std::bitset<8> two(v[x+1]);
std::bitset<8> three(v[x+2]);
std::bitset<8> four(v[x + 3]);
std::wostringstream outs1;
outs1 << "x[" << x << "] = " << one << " x[" << x + 1 << "] = " << two << " x[" << x + 2 << "] = " << three << " x[" << x + 3 << "] = " << four << std::endl;
OutputDebugString(outs1.str().c_str());
x += 4;
}
Output is:

This is expected. After you've uploaded texture memory to the GPU, if you Map it back for read, there's no guarantee that it will come back with the same pitch that you uploaded it as. This is because on upload, the driver re-lays out memory in a way that's optimal for rendering. When you bring it back to the CPU, the driver efficiently converts it back to linear format, usually in a way that reflects various properties of the texture cache or page size.

I am trying to connect to HiveMQ MQTT Broker from my ESP8266, 2 months ago, this code works fine, but now, when I implement more features, the code run with a lot of Exceptions. Sometimes, Exception (28), I'm newbie in this fields and don't know the way to handle it, thanks for your helps.

This crash happens when I added file download function, but I hasn't found an error. Global variables remaining 36% of RAM, but all temp String variables are freed after finishing function automatically. So chunk server sending is collecting a much of junk?
I think that this can happen when converting char to char*. The read function returns a char and at the end of c-strings it should always be null and when converting it is not. Perhaps there is an error in this
I add a mtd partition (512kb) to save panic log by mtdoops on an arm based embedded devices(kernel v4.4).
I trigger the panic using "echo c > /proc/sysrq-trigger".
After the device reboot observe the kernel panic logs in the Oops partition by "strings", but the panic log seems to be truncated(limit in 2kb?).
How to change the limit of mtdoops?

__NSCFString is a class cluster of NSString, you could convert it as is NSString *, no print (call - (NSString *)description) to get hex string needed.
NSData *routeData = [dictSelectedScheduleTrip valueForKey:#"routeSerialize"];
if ([routeData isKindOfClass:NSString.class]) {
routeData = [(NSString *)routeData dataUsingEncoding:NSUTF8StringEncoding]; // or your other prefer data encoding.
}
I need to acquire some points' coordinates (represented by variables xCoord and yCoord) and set to 1 the associated positions in matrix scan_image. It may happen that a point's coordinates are outside matrix's dimensions, so scan_image needs to be resized before setting point's associated position in matrix to 1.
Here's the code:

float currentY = 0;
for(int i = 0; i<(int)vecCI.size(); i++)
{
/* get current info */
listener::completeInformation ci = vecCI[i];
float xCoord = ci.position.first;
float yCoord = ci.position.second;
/* matrix is void */
if(scan_image.empty())
{
cout << "case 1" << endl;
/* create a new row */
Mat firstRow = Mat::zeros(yCoord+1, xCoord+1, CV_32FC1);
scan_image.push_back(firstRow);
/* set element to 1 */
scan_image.at<float>(xCoord, yCoord) = 1;
/* update matrix size */
currentX = xCoord;
currentY = yCoord;
}
/* new coordinate is outside current matrix */
else if (xCoord > currentX && yCoord > currentY)

}

}
I tried many options to modify scan_info's dimensions (you'll find them in comments) in case denoted as CASE 3, but everytime I get a bad memory error:
