# ------------------------------
#
# Public methods
#
#	drawttftext(fontsize,angle,x,y,text,colorIndex,fontfile) 
#	Writes text to the image using TrueType fonts 
#	fontsize	The font size. Depending on your version of GD, this should be specified as the pixel 
#			size (GD1) or point size (GD2)
#	angle		The angle in degrees, with 0 degrees being left-to-right reading text. Higher values 
#			represent a counter-clockwise rotation. For example, a value of 90 would result in 
#			bottom-to-top reading text. 
#	x,y		The coordinates given by x and y will define the basepoint of the first character 
#			(roughly the lower-left corner of the character). 
#	colorIndex	0=White	1=Black
#	fontfile	Location and name of the ttf file to use
#	see php imagettftext() for more details
#
#	drawtext(fontsize,x,y,text,colorIndex) 
#	Writes text to the image using built-in font
#	fontsize	The font size. From 1 to 5
#	x,y		The coordinates given by x and y will define the basepoint of the first character 
#			(roughly the lower-left corner of the character). 
#	colorIndex	0=White	1=Black
#	see php imagestring() for more details
#
#	rectangle(x1,y1,x2,y2,colorIndex,filled)
#	Creates a rectangle starting at the specified coordinates.
#	x1,y1		Upper left x,y coordinate. 0,0 is the top left corner of the image. 
#	x2,y2		Bottom right x,y coordinate 
#	colorIndex	0=White	1=Black
#	filled		Boolean, optional (default if False)
#	see php imagerectangle() and imagefilledrectangle() for more details	
#
#	ellipse(cx,cy,width,height,colorIndex,filled) 
#	Draws an ellipse centered at the specified coordinates.
#	cx,cy		x-coordinate and y-coordinate of the center 
#	width		the ellipse width 
#	height		the ellipse height 
#	colorIndex	0=White	1=Black
#	filled		Boolean, optional (default if False)
#	see php imageellipse() and imagefilledellipse() for more details	
#
#	line(x1,y1,x2,y2,colorIndex) 
#	Draws a line
#	x1,y1		x,y coordinates for the first point
#	x2,y2		x,y coordinates for the second point
#	colorIndex	0=White	1=Black
#	see php imageline() for more details
#
#	setGDImage(image) 
#	Imports an externally generated GD image
#	image		GD image to import
#
#	getGDImage() 
#	Exports the current GD image
#
#	setFontPath(fontpath)
#	Set directory path for the fonts to use
#	fontpath	Directory for the ttf fonts
#	Default value
#		Windows based platform		C:\Windows\Fonts
#		Linux based platform			../fonts
#
# Example 1
#	require_once('AastraIPPhoneGDImage.class.php');
#	$PhoneImageGD = new AastraIPPhoneGDImage();
#	$time = strftime("%H:%M");
#	$PhoneImageGD->drawttftext(30, 0, 10, 39, $time, 1,'Ni7seg.ttf');	
#
# Example 2
#	require_once('AastraIPPhoneGDImage.class.php');
#	$PhoneImageGD = new AastraIPPhoneGDImage();
#	$utf8text = "&#19996;&#19997;&#19998;&#19999;&#20024;";
#	$PhoneImageGD->drawttftext(20, 0, 5, 35, $utf8text, 1,'arialuni.ttf');
