Consider two ways to draw a rectangle:
//---------------------------------------------
int x=10;
int y=10;
int w=2;
int h=2;
canvas.drawRect(x,y,x+w,y+h,p); // (1)
float[] lines=new float[]{
x,y,x+w,y,
x+w,y,x+w,y+h,
x+w,y+h,x,y+h,
x,y+h,x,y
};
canvas.drawLines(lines,p); // (2)
//---------------------------------------------
You may think that they both produce same rectagle, but you would be
wrong.
Call (2) draws a rectangle without bottom-right pixel. (Call (1) draws
rectangle correctly.)
This is because drawLine doesn't draw endpoint's pixel. So
drawLine(0,0,2,0) draws 2 pixels, not three. Hence the missing pixel
at the bottom-right (drawLines also sorts points, so bottom line is
drawn from (x,y+h) to (x+w,y+h)).
This behaviour is different from J2ME's & J2SE's, where drawLine
always draws both endpoints, and drawing rectange with drawLine
produces same result as drawRect.
The question is: is this a bug?
