TImage attributes.

Image attributes are:

Image Quality (see EImageQuality for the list of qualities)
Compression defines the compression rate of the color data in the internal image structure. Speed and memory depends on this rate, but not the image display itself 0: no compression; 100: max compression
Radio Flag: kTRUE the x/y radio of the displayed image is always identical to the original image kFALSE the x and y size of the displayed image depends on the size of the pad
Palette: Defines the conversion from a pixel value to the screen color

This class is used (in general by secondary inheritance) by some other classes (image display).

Member Enumeration Documentation

◆ EImageQuality

enum TAttImage::EImageQuality

Enumerator
kImgDefault
kImgPoor
kImgFast
kImgGood
kImgBest

Definition at line 69 of file TAttImage.h.

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]	lquality	must be one of EImageQuality (kImgDefault is same as kImgGood in the current implementation)
[in]	lcompression	defines 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]	constRatio	keeps the aspect ratio of the image constant on the screen (in pixel units)

◆ ~TAttImage()

TAttImage::~TAttImage ( )

virtual

TAttImage destructor.

◆ 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 103 of file TAttImage.h.

◆ SetImageQuality()

virtual void TAttImage::SetImageQuality ( EImageQuality lquality )

inlinevirtual

Definition at line 105 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.
