# 2 Dimensional Translation in C program | CS1355-Graphics & Multimedia Lab

Translation is a simple straight line movement of the object in x and y direction. We define an image in coordinate system, to display that image Or object. Transformation is refer to transform from one position to another position depends upon there transformation it is classified into.Scaling.Shearing.Reflection.Rotation see the source code in C coding
