DrawRectangle (xLIB palette, TI-OS VALUES) #

real(7,7,X0,Y0,WIDTH,HEIGHT,COLOUR,UPDATELCD):
X0 = left x value
Y0 = top y value
WIDTH = width of rectangle
HEIGHT = height of rectangle
COLOUR = colour index (standard xLIB palette)
UPDATELCD = 0/1 to update LCD after drawing

This function draws a rectangle starting at X0,Y0 for WIDTH,HEIGHT using the custom xLIB palette

InvertRectangle (TI-OS VALUES) #

real(7,8,X0,Y0,WIDTH,HEIGHT,UPDATELCD):
X0 = left x value
Y0 = top y value
WIDTH = width of rectangle
HEIGHT = height of rectangle
UPDATELCD = 0/1 to update LCD after drawing

This function draws a rectangle starting at X0,Y0 for WIDTH,HEIGHT with inverted colours

FillRectangle (xLIB palette, TI-OS VALUES) #

real(7,9,X0,Y0,WIDTH,HEIGHT,COLOUR,UPDATELCD):
X0 = left x value
Y0 = top y value
WIDTH = width of rectangle
HEIGHT = height of rectangle
COLOUR = colour index (standard xLIB palette)
UPDATELCD = 0/1 to update LCD after drawing

This function draws a filled rectangle starting at X0,Y0 for WIDTH,HEIGHT using the custom xLIB palette

InvertFilledRectangle (TI-OS VALUES) #

real(7,10,X0,Y0,WIDTH,HEIGHT,UPDATELCD):
X0 = left x value
Y0 = top y value
WIDTH = width of rectangle
HEIGHT = height of rectangle
UPDATELCD = 0/1 to update LCD after drawing

This function draws a filled rectangle starting at X0,Y0 for WIDTH,HEIGHT with inverted colours

DrawCircle (TIOS VALUES) #

real(7,11,XCENTRE,YCENTRE,RADIUS,COLOUR,UPDATELCD:
XCENTRE = centre x value
YCENTRE = centre y value
RADIUS = radius of circle
COLOUR = colour index (standard xLIB palette)
UPDATELCD = 0/1 to update LCD after drawing

This function will draw a circle (outline only) with its centre at XCENTRE,YCENTRE for RADIUS using the custom xLIB palette

DrawFilledCircle (TIOS VALUES) #

real(7,12,XCENTRE,YCENTRE,RADIUS,COLOUR,UPDATELCD:
XCENTRE = centre x value
