Function Documentation

string RFileExt

(

const string &

name

)

Function returning file name extansion.

Parameters

name

file name

Referenced by RAnimSequence3D::CreateSequences(), and RSetFileExt().

string RFileBaseName

(

const string &

name

)

Function returning base file name, without directory and without extansion.

Parameters

name

file name

Referenced by RAnimSequence3D::CreateSequences().

string RFileDirName

(

const string &

name

)

Function returning the file directory from the file name.

Parameters

name

file name

string RSetFileExt	(	const string &	name,
		const string &	ext
	)

Function that sets a selected extansio to a file name. If the file name does not already have an extansion, it is added.

Parameters

name	base name
ext	extansion

Color_t RGetColor	(	const string &	color_str,
		Color_t	default_val
	)

Read a ROOT color code in a string, either as an integer color code, either as a #RRGGBB code, where RR, GG and BB are the hexadecimal values for color components.

Parameters

color_str	input string
default_val	default value in case of error

Referenced by RString::ReadColor(), and RString::ReadSubColor().

string RColorString	(	Color_t	c,
		Color_t	c_max
	)

Write a ROOT color definition in a string. The color is written as a ROOT color number if the color number is lower than c_max, else it is written as its components: #RRGGBB.

Parameters

c	color number
c_max	maximum color number for color codes, after which #RRGGBB is written

void RSetPaletteZero	(	const Double_t	vmin,
		const Double_t	vmax,
		const Double_t	vctr,
		const Int_t	ncol,
		const Double_t *	rgb_min,
		const Double_t *	rgb_max,
		const Double_t *	rgb_ctr
	)

Function that defines a color palette, from a central color to colors defined for lowest and highest values.

For example, for an histogram with values ranging from -1 to +1, using default values, the functions creates a palette ranging from blue to white for values between -1 and 0, and from white to red for values ranging from 0 to 1.

Colors are defined with RGB values.

Parameters

vmin	lower value (histograme scale)
vmax	upper value (histograme scale)
vctr	central value
ncol	number of colors for the palette
rgb_min	RGB color at lower value
rgb_max	RGB color at upper value
rgb_ctr	RGB color at central value

void RSetPaletteZero	(	const TH1 *	hptr,
		const Double_t	vctr,
		const Int_t	ncol,
		const Double_t *	rgb_min,

		const Double_t *	rgb_ctr
	)

Colors are defined with RGB values.

Parameters

hptr	histogram from whiwh lower and upper values are taken
vctr	central value
ncol	number of colors for the palette
