Image scaling - Wikipedia
en.wikipedia.org › wiki › Image_scalingBilinear interpolation works by interpolating pixel color values, introducing a continuous transition into the output even where the original material has discrete transitions. Although this is desirable for continuous-tone images, this algorithm reduces contrast (sharp edges) in a way that may be undesirable for line art.
Bilinear interpolation - Wikipedia
en.wikipedia.org › wiki › Bilinear_interpolationIn mathematics, bilinear interpolation is a method for interpolating functions of two variables (e.g., x and y) using repeated linear interpolation.It is usually applied to functions sampled on a 2D rectilinear grid, though it can be generalized to functions defined on the vertices of (a mesh of) arbitrary convex quadrilaterals.
Linear interpolation - Wikipedia
https://en.wikipedia.org/wiki/Linear_interpolationIf a C function is insufficient, for example if the process that has produced the data points is known to be smoother than C , it is common to replace linear interpolation with spline interpolation or, in some cases, polynomial interpolation. Linear interpolation as described here is for data points in one spatial dimension. For two spatial dimensions, the extension of linear interpolation is …

(9.2) Mp = D R × Sp L + D L × Sp R + D T × Sp B + D B × Sp T D R + D L + D T + D B, where Mp is the missing pixel, Sp L, Sp R, Sp T, Sp B are the left, right, top, and bottom source pixels, and D L, D R, D T, and D B are the corresponding distances from the missing pixel.
