Image effects

Bilinear

Re-calculates the picture if there is size change by taking into account the

upper and lower pixels for the recalculation. This method is fast and espe-

cially suitable for drawings and illustrations.

Bilinear

(Bartlett)

If there is a size change, the picture is re-calculated by taking into account

the surrounding pixels in different parts. Though more exact for picture

size reductions than the simple bilinear method, it is slower. This method

produces the best results for drawings and illustrations.

Bicubic

If there is a size change, the picture is recalculated by taking into account

all adjacent pixels during the recalculation. This method is particularly

suited for realistic photos. The edges and lines are retained relatively well.

However, the method may produce artefacts on sharp edges and is there-

fore not well suited for drawings.

Lanczos

If there is a size change, this recalculates the picture by taking into ac-

count the surrounding pixels in a defined ratio to the recalculation. This

method is qualitatively the best and thus requires the most time to calcu-

late. It is especially well suited for detailed half-tone photos. However the

method may produce artefacts on sharp edges and is therefore not well

suited for drawings.
