"gc" is the Graphics Context.
All these functions are called like that : gc:function(...)

Quick Overview

• begin -
• clipRect(?, x, y, width, height) -
• drawArc(x, y, width, height, start angle, finish angle).
• drawImage(image,x,y) First argument in format “TI.Image”, x and y the coords.
• drawLine(xstart, ystart, xend, yend) Draws a line starting at the point (xstart,ystart) and ending at the point (xend, yend)
• drawPolyLine(int list1 [,int list2, .., int listN]) Draws a shape from a list contaning successively the x and y coordinates of each point the line have to draw.
• drawRect(x, y, xwidth, yheight) Draws a rectangle at (x,y) with the “x” side being “xwidth” long and the “y” side being “yheight” long
• drawString(string, x, y, position) position is the string’s anchor point and can be "baseline", “bottom”, “middle”, or “top”.
• fillArc(x, y, width, height, start angle, finish angle) see drawArc
• fillPolygon(int list1 [,int list2, .., int listN]) see drawPolyLine
• fillRect(x, y, width, height) see drawRect
• finish -
• getStringHeight(string) - Returns the string's height.
• getStringWidth(string) - Returns the string's width
• isColorDisplay Bool (Read-only) Returns 1 if the device has a color display, 0 if not.
• setAlpha(alpha) - where alpha is an integer between 0 and 255. Sets the transparency.
• setColorRGB(red, green, blue) RGB values are integers, from 0 to 255.
• setFont(font, type, size), with font : {“sansserif”, "serif", ..}, type {“b”, “r”, “i”}, size(int)
• setPen(thickness, smoothness) : thickness {“thin”, “medium”, "thick"}, smoothness {“smooth”, "dotted", "dashed"}
