FAQPage Schema

How do I remove halo artifacts from pixel art sprites?▼

Removing halo artifacts from pixel art sprites is done by remediating imperfect alpha and fringe fragments using a Node CLI, which cleans native-resolution edges without altering core shapes.

Can I batch process an entire folder of Aseprite sprites to fix alpha fringing?▼

Yes, you can batch process an entire folder of Aseprite sprites to fix alpha fringing by passing the folder path to the CLI, which remediates halo fragments across multiple files automatically.

What causes halo fragments around handmade pixel art assets?▼

Halo fragments around handmade pixel art assets are caused by imperfect alpha channels during generation, leaving unwanted semi-transparent fringe pixels around character edges that require remediation.

Is it safe to overwrite original sprite files in place when cleaning alpha?▼

Yes, it is safe to overwrite original sprite files in place when cleaning alpha if you specify the overwrite flag in the CLI, though maintaining backups of native-resolution assets is advised.

Does the pixelart-cleanup Node CLI work with PixelLab sprite pipelines?▼

Yes, the pixelart-cleanup Node CLI works with PixelLab sprite pipelines by targeting native-resolution assets, remediating halo fragments, and preserving edge clarity without affecting core shapes.
