Higher depth creates larger images but takes longer to process.
Hilbert Curve preserves image structure best by keeping similar colors together.
PNG is recommended to preserve exact color values.
What is an AllRGB Image?
An AllRGB image is a picture that contains every possible color in the RGB spectrum exactly once. For example, an 18-bit AllRGB image contains exactly 262,144 unique pixels, each representing a unique color from the 18-bit color space.
-
Unique Colors: Every pixel is mathematically unique.
-
Artistic Conversion: Your uploaded images are used as a reference to organize the colors, creating a unique mosaic effect.
-
Hilbert Curve Mapping: Uses advanced space-filling curves to maintain image structure while strictly adhering to the unique color constraint.
