Constant Summary collapse
- NEAREST =
Nearest neighbor sampling; this is the fastest
and lowest quality mode. Quality is normally unacceptable when scaling down, but may be OK when scaling up.
0 or :nearest
- TILES =
This is an accurate simulation of the PostScript
image operator without any interpolation enabled. Each pixel is rendered as a tiny parallelogram of solid color, the edges of which are implemented with antialiasing. It resembles nearest neighbor for enlargement, and bilinear for reduction.
1 or :tiles
- BILINEAR =
Best quality/speed balance; use this mode by
default. Bilinear interpolation. For enlargement, it is equivalent to point-sampling the ideal bilinear-interpolated image. For reduction, it is equivalent to laying down small tiles and integrating over the coverage area.
2 or :bilinear
- HYPER =
This is the slowest and highest quality
reconstruction function. It is derived from the hyperbolic filters in Wolberg's "Digital Image Warping", and is formally defined as the hyperbolic-filter sampling the ideal hyperbolic-filter interpolated image (the filter is designed to be idempotent for 1:1 pixel mapping). **Deprecated**: this interpolation filter is deprecated, as in reality it has a lower quality than the <b>GDK_INTERP_BILINEAR</b> filter (Since: 2.38)
3 or :hyper
