I have a document which containing some elements.  I am trying to show it in a webview but in a smaller size than the original size.  The problem is that I don´t get the correct positions in of the different spots in the webview. I got the correct size of the new spots but not the position. I made the calculations in the following way:


Original size (INDD document)

DocumentWidth = 768

DocumentHeight = 1024

New Size (Size of the webview)

Width = 522

Height = 696


percentW = newWidth(Webview)/DocumentWidth

percentH = newHeight(Webview)/DocumentHeight;

From these percent values I am calculating all the new values I will need in the ImageMapper (top,left,bottom,right).


Formula for that


myPrecent = (percentW/percentH) * 100;

        result =  myPrecent * ((top,left,right,bottom) / 100);


I suppose that I am thinking wrong in my calculation but I cant figured out what I´m doing wrong. So I will be appreciate if someone has any idea what I have doing wrong.

Hi Chintoo, 

try this:

verticalScaling = Height/DocumentHeight

horizontalScaling = Width/DocumentWidth

newTop = Top * verticalScaling

newLeft = Left * horizontalScaling

newBottom = Bottom * verticalScaling

newRight = Right * horizontalScaling
