How to increase the accuracy of measurements in iTextSharp?

Tags: measurementsaccuracyiText 5

I want to resize a pdf to a specific size, but when I use scaling it loses accuracy because a float rounds the value. How can I avoid this and make measurements more accurate?

The ByteBuffer class has a public static variable named HIGH_PRECISION. By default, it is set to false. You can set it to true so that you get 6 decimal places when rounding a number:

iTextSharp.text.pdf.ByteBuffer.HIGH_PRECISION = true;

That will cost you some performance (but maybe you'll hardly notice that) and the resulting file will have more bytes (but measurements will be more accurate).
