About This Tool

Purpose-built to translate general images into LCD-ready data, this tool targets hardware and firmware teams performing display validation. It maps pixels to a fixed palette, applies quantization and optional dithering, and outputs formats usable by common LCD controllers. Conceptually, the process preserves structure while adapting color depth and sub-pixel layout to the target panel. The result supports rapid hardware testing, regression checks, and firmware QA across multiple color depths and resolutions. Core features include configurable color_depth_bits, dithering_method choices, and optional gamma correction to better mimic real hardware. Outputs include a palette table and an indexed pixel map suitable for embedded software pipelines, plus a preview bitmap for quick assessment. The tool is differentiated by deterministic results, batch-friendly exports, and palettes generated from target color spaces, enabling repeatable comparisons across firmware builds and hardware revisions.

How to Use

Provide inputs: upload the source image, set width_px, height_px, color_depth_bits, and dithering_method.
Choose quantization: select a target palette or generate from color space presets.
Run conversion: the tool maps each source pixel to a palette index and applies optional dithering.
Retrieve outputs: export pixel_indices, palette, and an optional preview image in PNG or JSON.
Validate results: compare the preview with expectations and adjust palette or depth if needed.

Frequently Asked Questions

Find Quick Answers

What inputs are required?

You must provide a source image, target dimensions in pixels, and a color depth in bits. Optional dithering and a palette may be supplied for deterministic results.

What formats are produced?

Outputs include a pixel index map, a color palette array, and a preview bitmap. Exports can be generated as JSON arrays or binary-like formats compatible with common LCD controllers.

How is color quantization performed?

Color values are mapped to the nearest color in the selected palette. When dithering is enabled, spatial error diffusion is applied to reduce banding and preserve detail.

Is this suitable for hardware drivers?

Yes. The produced data aligns with typical LCD controller expectations and provides deterministic, testable results for firmware validation and hardware-in-the-loop workflows.
