This article was prepared with AI assistance based on an analysis of the current Lumina Studio source code, existing Wiki content, and relevant workflows. It has been checked against the current version, but omissions or details that become outdated may remain as the software evolves. If you find an error or have a clearer explanation, example, or suggestion, please leave a comment on this page or propose an edit on GitHub.
Colors, Smoothness, and Detail
The basic controls decide how many colors are retained and how the contours balance source fidelity against simpler paths.
Number of Colors
Auto uses an internal value of 0. The vectorizer determines a palette size from the image and reports the resolved count in the result summary.
Switch to Manual to choose 2–256 colors. This value is the K-Means palette size used by color segmentation, not the number of SVG shapes:
- Lower values consolidate similar colors into larger, more uniform regions.
- Higher values retain more gradients and local color differences, but can create more fragments.
For icons or pixel art with a known palette, the original color count is a useful starting point. Otherwise, Auto is a sensible first pass.
Smoothness
The range is 0–1, with a default of 0.5. It controls contour decimation and smoothing:
- Near
0, more original turns and small details are retained, usually with more path nodes. - Near
1, paths become smoother and simpler, but sharp corners and small irregularities may be weakened.
Smoothness is not a color-noise filter. If the output contains many tiny color regions, also inspect Preprocessing and Region Filtering.
Detail Level
Detail Level is off by default, represented internally by -1. In this mode, each advanced parameter is used independently.
When enabled, its range is 0–1 and it starts at 0.5. It is a unified detail control that lets the vectorization engine coordinate several detail-related parameters:
- Lower values favor simpler regions and paths.
- Higher values favor retaining more edges and small structures.
It does not change the palette size, and it does not rewrite the advanced values displayed in the UI. Turn it off when you need reproducible control over one specific stage.
