vtk - Know slice number? -


I have a DICOM series with the following original, spacing and range: 

  int NExtent [6]; Double despection [3]; Double daugin [3]; M_pReader-> GetOutputInformation (0) - & gt; Go (vtkStreamingDemandDrivenPipeline :: WHOLE_EXTENT (), nExtent); M_pReader-> GetOutput () - & gt; GetSpacing (dSpacing); M_pReader-> GetOutput () - & gt; GetOrigin (dOrigin);

Where m_pReader is a vtkDICOMReader object ...

degrade 0, 0, 0;

DSPIID ID 0.447266, 0.447266, 3. 998718;

nExtent is 0, 511, 0, 511, 0, 43;

The series is axial now, if I slice the chain through the axial scheme, then I can split the series with 44 slices, such as: 

  Double delta = 0.0; Delta + = 1.0; PReslice-> Updates (); Double dSliceSpacing = pReslice-> GetOutput () - & gt; GetSpacing () [2]; VtkMatrix4x4 * pMatrix = pReslice-> GetResliceAxes (); // Transfer to Disentant Deportes that we are smashing through Double Depot [4]; Double Dee Center [4]; DPoint [0] = 0.0; DEPUT [1] = 0.0; DEPUT [2] = DSLICI Spacing * Delta; DEPUT [3] = 1.0; PMatrix-> Multipoint (dPoint, dCenter); PMatrix-> Set aliment (0, 3, de center [0]); PMatrix-> Set aliment (1, 3, de center [1]); PMatrix-> Set aliment (2, 3, denter [2]);

Everything is fine ...

Problem: If I slice the chain through the coronal plan, slices are not 44 !! But how many people? If Coronal or Sagittal is planned then how can I know the slice number?

For example

For example < / P>

For example, for each axis (X, Y, Z) you need to calculate your minimum / maximum origin 

  myOriginMax.x = myOrigin.X + ((ImageDimension.SizeX - 1) * mySpacing.X);

You can calculate your new origin at your slicing event, where _positionDelta is your inc / dec value. (More or less proxy code)

e.g. 

  double [] _origin = myImageReslice.GetResliceAxesOrigin (); If (_view == "segel") {_origin [0] = monastery (_origin [0] + _position_delata * mySpacing.X, myOriginMax.x); } And if (_view == "coronal") {_origin [1] = monastery (_origin [1] + _position delta * mySpacing.Y, myOriginMax.Y); } And // XAC {_origin [2] = Math.min (_origin [2] + _positionDelta * mySpacing.Z, myOriginMax.Z); } MyImageReslice.SetReliceAxesOrigin (_origin [0], _origin [1], _origin [2]); to present();

html - CSS autoheight, but fit content to height of div -

I have a div in which there are three children- div in the left and middle div: float: left while true: float: true because it is my layout Actually will spoil, I've used ClearFix Hack: .cf {zoom: 1; }. Cf: First,. Cf: {content: ""; Display: Table; }. Cf: After {clear: both; } It still works, but I want to be the right div an indicator. So it should fill 100% of the parent unit of height. How can I complete this? PS is the full code: & Lt; / Div & gt; & Lt; Div class = "mobile_content" & gt; & Lt; H5 & gt; {{Data.titel}} & lt; / H5> & Lt; Table & gt; & Lt; TR & gt; & Lt; Th & gt; Komponist: & lt; / Th & gt; & Lt; TD & gt; {{Data.komponist}} & lt; / TD & gt; & Lt; / TR & gt; & Lt; TR & gt; & Lt; Th & gt; Instrument: & lt; / Th & gt; & Lt; TD & gt; {{Data.instrumente}} & lt; / TD & gt; & Lt; / TR & gt;...

qt - How to prevent QAudioInput from automatically boosting the master volume to 100%? -

I have been trying to use Qt5 multimedia to record audio with QAudioInput, however, when I see If QAudioInput is started, it increases the master volume of my sound device to 100%. How can I prevent QAudioInput from changing the master volume? My current development platform is Linux with PalsAdio (with flat audio disabled). How can I use QAudioInput : QAudioDeviceInfo device_info = QAudioDeviceInfo :: defaultInputDevice (); QAudio format format; Format.setSampleRate (44100); Format.setChannelCount (1); Format.setSampleSize (16); Format.setCodec ("Audio / PCM"); Format.setSampleType (QAudioFormat :: SignedInt); Format.setByteOrder (QAudioFormat :: LittleEndian); Std :: cout & lt; & Lt; Device_info.deviceName ().
