UpsamplingFilters

Scaling filters perform upsampling and downsampling on the image, making it larger or smaller without making it look blocky or jagged.

Besides bilinear and bicubic filtering, Sclender offers "dejag" filters to make the image look better without losing detail. Such filters can "depixelize" an image that has been upscaled without filtering.

Reconstructive Upscalers

Dejag

This filter reduces blockiness in an upscaled image by reconstructing its geometry. It is especially useful for low-res sprites.

Dejag Dither

This filter reduces blockiness in an upscaled image by reconstructing its geometry without any blending, resulting in a grainy appearance. It is acceptable if the image will be seen from a distance, or is followed up with a blurring-type filter.

Dejag Fast

This filter reduces blockiness in an upscaled image by reconstructing its geometry, but does not preserve details as well as Dejag, making it somewhat faster to use. A good compromise between Dejag and Dejag Dither on slower machines.

Dejag Plus

This filter is like Dejag, but works harder to respect the artist's intentions. It is slightly more demanding than Dejag.

Dejag Arc

This filter reduces blockiness in an upscaled image by reconstructing geometry while paying more attention than to arc patterns than Dejag does. "Curved stair" effects are mitigated when anti-aliasing diagonal lines and edges, making it exceptionally good for low-resolution 3D.

High-quality Upscalers

Dejag High-Quality (HQ)

This filter reduces blockiness in an upscaled image by reconstructing its geometry. Results are much better than with Dejag and Dejag Plus, but requires a fast machine to get good FPS.

Dejag Arc Plus

This filter combines Dejag HQ and Dejag Arc to faithfully recreate the details in an image. Results are much better than with Dejag Arc, but requires a fast machine to get good FPS.
