onOne Software Perfect Resize full review
Previously called Genuine Fractals, Perfect Resize is one of the big names in image resizing. There are common document presets to choose from or a new size can be manually input. The important features here are texture control and sharpening.
Texture enhancement is added after clicking OK, while sharpening is applied to the full-screen preview. The texture control also has presets for low-res JEPGs, portraits, landscapes and high detail or you can manually adjust the settings. The sharpening has a choice of unsharp mask, high pass or progressive. You may be better turning this off though. There are also options for adding grain to featureless areas, tiling and image wrapping.
The host of texture options depend on image type and detail required
