Constructor & Destructor Documentation

◆ TAttImage() [1/2]

TAttImage::TAttImage ( )

TAttImage default constructor.

Calls ResetAttImage to set the attributes to a default state.

Definition at line 524 of file TAttImage.cxx.

◆ TAttImage() [2/2]

TAttImage::TAttImage ( EImageQuality  lquality,
UInt_t  lcompression,
Bool_t  constRatio 
)

TAttImage normal constructor.

Image attributes are taken from the argument list

Parameters
[in]lqualitymust be one of EImageQuality (kImgDefault is same as kImgGood in the current implementation)
[in]lcompressiondefines the compression rate of the color data in the image. Speed and memory depends on this rate, but not the image display itself 0: no compression; 100: max compression
[in]constRatiokeeps the aspect ratio of the image constant on the screen (in pixel units)

Definition at line 544 of file TAttImage.cxx.

◆ ~TAttImage()

TAttImage::~TAttImage ( )
virtual

TAttImage destructor.

Definition at line 559 of file TAttImage.cxx.

◆ ResetAttImage()

void TAttImage::ResetAttImage ( Option_t option = "")
virtual

Reset this image attributes to default values.

Default values are:

  • quality: kImgPoor, (no smoothing while the image is zoomed)
  • compression: 0 (no compression)
  • constRatio: kTRUE
  • palette: a default rainbow palette

Definition at line 584 of file TAttImage.cxx.

◆ SaveImageAttributes()

void TAttImage::SaveImageAttributes ( std::ostream &  out,
const char *  name,
EImageQuality  qualdef = kImgDefault,
UInt_t  comprdef = 0,
Bool_t  constRatiodef = kTRUE 
)
virtual

Save image attributes as C++ statement(s) on output stream, but not the palette.

Definition at line 620 of file TAttImage.cxx.

◆ SetConstRatio()

void TAttImage::SetConstRatio ( Bool_t  constRatio = kTRUE)
virtual

Set (constRatio = kTRUE) or unset (constRadio = kFALSE) the ratio flag.

The aspect ratio of the image on the screen is constant if the ratio flag is set. That means one image pixel is always a square on the screen independent of the pad size and of the size of the zoomed area.

Definition at line 641 of file TAttImage.cxx.

◆ SetImageCompression()

virtual void TAttImage::SetImageCompression ( UInt_t  lcompression)
inlinevirtual

Definition at line 97 of file TAttImage.h.

◆ SetImageQuality()

virtual void TAttImage::SetImageQuality ( EImageQuality  lquality)
inlinevirtual

Definition at line 99 of file TAttImage.h.

◆ SetPalette()

void TAttImage::SetPalette ( const TImagePalette palette)
virtual

Set a new palette for the image.

If palette == 0 a default rainbow color palette is used.

Reimplemented in TASImage.

Definition at line 650 of file TAttImage.cxx.

◆ SetPaletteEnabled()

virtual void TAttImage::SetPaletteEnabled ( Bool_t  on = kTRUE)
inlinevirtual

Reimplemented in TASImage.

Definition at line 96 of file TAttImage.h.

◆ StartPaletteEditor()

void TAttImage::StartPaletteEditor ( )
