Member Function Documentation

toImageData()

static bool pqImageUtil::toImageData ( const QImage &  img, vtkImageData *  vtkimage  )

static

convert a QImage to a vtkImageData of type VTK_UNSIGNED_CHAR.

Use RGB(A) format.

fromImageData()

static bool pqImageUtil::fromImageData ( vtkImageData *  vtkimage, QImage &  img  )

static

convert vtkImageData of type VTK_UNSIGNED_CHAR to QImage Z axis is ignored.

Use RGB for 3 components data, RGBA for 4-components data.

imageDataToFormatedByteArray()

static bool pqImageUtil::imageDataToFormatedByteArray ( vtkImageData *  vtkimage, QByteArray &  bArray, const char *  format  )

static

Convert vtkImageData of type VTK_UNSIGNED_CHAR to a QByteArray containing a buffered version of the image saved in the given format.

Z axis is ignored. Use RGB for 3 components data, RGBA for 4-components data. Available format values are given by QImageWriter::supportedImageFormats().

saveImage() [1/2]

static int pqImageUtil::saveImage ( vtkImageData *  vtkimage, const QString &  filename, int  quality = -1  )

static

Save an image to a file.

Determines the type of the file using the file extension. Returns the vtkErrorCode on error (vtkErrorCode::NoError i.e. 0 if file is successfully saved). quality [0,100] – 0 = low, 100=high, -1=default

saveImage() [2/2]

static int pqImageUtil::saveImage ( const QImage &  image, const QString &  filename, int  quality = -1  )

static

Save an image to a file.

Determines the type of the file using the file extension. Returns the vtkErrorCode on error (vtkErrorCode::NoError i.e. 0 if file is successfully saved). quality [0,100] – 0 = low, 100=high, -1=default
