Publisher description for SPLINE RESIZE

SPLINE RESIZE program icon

It enables you to MASSIVELY resize a bitmap, say from 300x200 up to 2048x1536, and still get a decent picture. It achieves this using a numerical mathematical technique called Cubic Spline Interpolation. The principle is simple, but the algebra looks complicated. It involves determining the coefficients for a cubic Equation (called a Lagrange Polynomial) to smoothly pass from one original pixel to the next. The number of calculations required is fairly stupendous, so I've only written the Algorithm in Assembler.
