About This Tool

The tool converts a raster image into an LCD-friendly bitmap suitable for embedded displays. It accepts common image formats and outputs data ready for firmware deployment. Target dimensions and color depth are defined per the display, ensuring compatibility with typical graphic LCDs and small OLED panels.
The processing pipeline includes resizing, optional cropping, color quantization to the chosen bit depth, and optional dithering to preserve detail in low-bit-depth outputs. It supports Floyd-Steinberg and Ordered (Bayer) dithering to balance quality and performance. Data layout can be configured for row-major or column-major memory organization to align with driver expectations. Output formats include C arrays, hex strings, Python literals, or JSON objects, enabling direct integration into firmware pipelines.
This tool is intended for embedded developers, hardware designers, and firmware engineers who need predictable, exportable bitmap data for display rendering. Its differentiation lies in focused support for LCD-native bit depths, explicit data packing, and convenient templates tailored to common microcontroller toolchains.

How to Use

Provide inputs: upload source image, set target width and height, select bits per pixel and dithering method.
Choose processing options: decide on scaling vs. cropping, and select memory layout (row-major or column-major).
Run conversion: execute the conversion to generate the bitmap data.
Review outputs: inspect the bitmap preview and copy or export the data as C array, hex string, or JSON.
Integrate: paste the generated data into the firmware project and align with the display driver.

Frequently Asked Questions

Find Quick Answers

What output formats are available?

The tool can export as C arrays, hex strings, Python literals, or JSON data, with accompanying width, height, and bit-depth metadata to simplify driver integration.

Which input formats are supported?

Common raster formats such as PNG, JPEG, BMP are accepted. Transparency is treated as background color based on the chosen depth.

What bit depths are supported?

Supported depths include 1, 2, 4, and 8 bits per pixel, enabling 1-bit monochrome up to 8-bit grayscale or indexed palettes depending on the driver.

Can I choose the memory layout for the output?

Yes. You can select row-major or column-major packing to match your LCD driver’s expected data order, reducing post-processing in firmware.
