Guna,

You can convert using this formula:

LengthCM = LenghtPixels * 2.54 / DPI

Where DPI is the resolution in dots per inch.

thanks for sending formula ....
Actually  I would like to have the  measurement in cm  while drawing Rectangle.
I have assumed the following things....

1.LengthPixel which u have mentioned in ur formula is the total no. of  pixel between the  two points(x1,y1) and (x2,y2).
I am using the following formula for calculating the total pixel count for rectangle.

2.Dpi which u have mentioned is Image Dpi or Screen dpi...

Please correct me if Iam wrong....

Guna,

What is the formula that you are referring to?

The DPI in the formula below is the Image Horizontal and vertical resolution (DPI)

LengthCM = LenghtPixels * 2.54 / DPI
