How to modify PXCCapture::Sample image in OnNewSample callback ?

[ippei_i_]

Hi,

I want to rotate capture image in PXCCapture::Sample for camera placed lengthwise, to the face detection module.

following code works fine.

pxcStatus PXCAPI OnNewSample(pxcUID, PXCCapture::Sample *sample)
{
    if(sample->color)
    {
        // modify capture image data test
        PXCImage::ImageInfo info = sample->color->QueryInfo();
        PXCImage::ImageData data;
        for(int i=0;i<34;i++)
        {
            // get original capture image data
            if(sample->color->AcquireAccess(PXCImage::ACCESS_READ_WRITE, info.format , &data) >= PXC_STATUS_NO_ERROR)
            {
                int pixelWidth = data.pitches[0]/info.width;
                for(int y=0;y<info.height;y++)
                {
                    for(int x=0;x<info.width;x++)
                    {
                        data.planes[0][y*data.pitches[0] + x*pixelWidth +0] = 0x00; // change red pixel.(test)
                    }
                }
                sample->color->ReleaseAccess(&data);
            }
            Sleep(1);
        }
    }

    // return NO_ERROR to continue, or any error to exit the loop
    if( isStopped )
        return  PXC_STATUS_EXEC_ABORTED;
    else
        return PXC_STATUS_NO_ERROR;
}

pxcStatus PXCAPI OnModuleProcessedFrame(pxcUID mid, PXCBase *module, PXCCapture::Sample *sample)
{
    if (mid==PXCFaceModule::CUID)
    {
        DrawBitmap(sample->color);
    }
}

But can't rotate rotate capture image in PXCCapture::Sample, because can't modify width and height.

How can I do?

Thanks.
