    text
    copied!<p>Process of scaling x,y coordinates of one rectangle to other rectangle coordinates is pretty simple as better explained at this link</p> <p><a href="http://www.icoachmath.com/math_dictionary/scale_factor.html" rel="nofollow">http://www.icoachmath.com/math_dictionary/scale_factor.html</a></p> <p>if we have two rectangle one is having Maxwidth: 2000 and Maxheight: 1000</p> <p>and second rectangle of size MaxWidth : 4000 and MaxHeight = 2000</p> <p>so scale factor for converting coordinate of rect1 to rect2 would be </p> <p>for x in rect2 : (x in rect1) * (MaxWidth of Rect2/ MaxWidht of Rect1) for y in rect2 : (y in rect1) * (MaxHeight of Rect2/ MaxHeight of Rect1)</p> <p>but what should be scale factor when </p> <p>for one rectangle center is origin(X,Y - 0,0) would be at the center and there would be negative values for x and y as well if you go left from center then x would be in negative and in right side it would be positive same for Y, if you go up then y would be positive but if you go to bottom, thenY Would be negative, so extents of this rectangle tends to ( -MaxWidth to +MaxWidth, -MaxHeight to +MaxHeight)</p> <p>Now we have second rectangle which is having center at most left and top most position (most left and top most-0,0) and as we have to travel in right direction along x axis and down along y axis, So there would be always positive values for x and y.</p> <p>So, how to calculate scale factor for converting coordiantes of rectangle which has the origin at center of rectanlge(MaxWidth/2,MaxHeight/2) to the rectanlge which has origin at most left and top most position</p>
