Pentasonic HifiColor GBASIC graphics commands

HCLSc

clears the graphical memory with the specified color c
see HCOLOR for the color coding. If no c is specified, the value of the previous HCLS is used.

HCOLORc

set the color to use with draw commands. Codes:

0: white (R+G+B)	4: yellow (R+G)
1: cyan (G+B)	5: green (G)
2: magenta (R+B)	6: red (R)
3: blue (B)	7: black ()

HPLOTx1,y1[TOx2,y2 [,B[F]]]

Five variants:

HPLOTx1,y1	draws a point at x1,y1
HPLOTx1,y1TOx2,y2	draws a straight line from x1,y1 TO x2,y2
HPLOTx1,y1TOx2,y2, B	draws a box from x1,y1 TO x2,y2
HPLOTx1,y1TOx2,y2, BF	draws a filled box from x1,y1 TO x2,y2
HPLOT@TOx2,y2, BF	draws a filled box from the previous x1,y1 TO x2,y2

HCIRCLEx, y, r [,q]

Two variations:

HCIRCLEx, y, r	draws a circle with the centre at x, y and radius r
HCIRCLEx, y, r, q	draws 1/8 of a circle, starting at 3 0'clock, counter-clockwise. q specifies the octant. Each bit in the value represents 1/8 of a circle (represented as "small hand" clock positions): 1 - 1:30 to 3:00 16 - 7:30 to 9:00 2 - 12:00 to 1:30 32 - 6:00 to 7:30 4 - 10:30 to 12:00 64 - 4:30 to 6:00 8 - 9:00 to 10:30 128 - 3:00 to 4:30

HPRINTx,y"message"

Write message to the display at coordinates x,y. Value for x is between 0 and 512, the value of y is between 0 and 47.

HAXEp,n,[X|Y]

Draws an horizontal ("X" specified) or vertical ("Y" specified) axis. The origin is defined by a previously executed HPLOTx,y command. p specifies the range and n specifies the number of intermediate grades.

This Basic extension is similar to the µInflux HRC 80 GBASIC.
