Can you enlarge a low-resolution image without causing pixelation?
When enlarging an image, the computer must generate new pixels that did not exist in the original file. Basic nearest-neighbor scaling repeats existing pixels, producing blocky pixelation. Bicubic interpolation, used by IMAZEOO, samples the 16 nearest surrounding pixels and calculates a smooth weighted color gradient, producing enlarged images with smooth curves and reduced aliasing.
Key Takeaways
- Enlarges dimensions by 2x (200%) or 4x (400%) scaling factors.
- Bicubic interpolation prevents harsh jagged edges and pixel staircasing.
- Honest limitation: Upscaling cannot restore optical camera detail that was never recorded.
- Best suited for moderately sized photos, digital artwork, and vector rasterizations.
