Conversion From Delphi 7XE to C/Cpp/C#

The existing application converts the input from a line scan camera into string values that are displayed on the software which we call the 'Line Scan Display'. A bit of trigonometry is involved which checks the change in values when an object is detected through the line-scan camera. A sensor is attached to the camera which sends the values to the computer. The platform it runs on is the usual Windows 7 64-bit and we plan to run it on both 32-bit and 64-bit processors for a better flexibility. I am attaching some files with this mail, please have a look at the code along with the pseudo code (which is not full, only a part of the original source code) and the calibration software's screenshot, which we are calling the "Line Scan Display".
