Quick Overview

• gc:begin - has to be called to initiate a dummy gc (before calling platform.gc() things)
• gc:clipRect(op, x, y, width, height) - Sets the clipping rectangle for subsequent graphics operations.
• gc:drawArc(x, y, width, height, start angle, finish angle).
• gc:drawImage(image,x,y) First argument in format “TI.Image”, x and y the coords.
• gc:drawLine(xstart, ystart, xend, yend) Draws a line starting at the point (xstart,ystart) and ending at the point (xend, yend)
• gc: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.
• gc: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
• gc:drawString(string, x, y, position) position is the string’s anchor point and can be "baseline", “bottom”, “middle”, or “top”.
• gc:fillArc(x, y, width, height, start angle, finish angle) see gc:drawArc
• gc:fillPolygon(int list1 [,int list2, .., int listN]) see gc:drawPolyLine
• gc:fillRect(x, y, width, height) see gc:drawRect
• gc:finish - has to be called to terminate a dummy gc (after calling platform.gc() things)
• gc:getStringHeight(string) - Returns the string's height.
• gc:getStringWidth(string) - Returns the string's width
• gc:setAlpha(alpha) - where alpha is an integer between 0 and 255. Sets the transparency.
• gc:setColorRGB(red, green, blue) RGB values are integers, from 0 to 255.
• gc:setFont(font, type, size), with font : {“sansserif”, "serif", ..}, type {“b”, “r”, “i”}, size(int)
• gc:setPen(thickness, smoothness) : thickness {“thin”, “medium”, "thick"}, smoothness {“smooth”, "dotted", "dashed"}
