The software supports multiple output syntaxes:
Before understanding the tool, you must understand the format. RGB 565 is a 16-bit color encoding scheme:
By packing a pixel into exactly 16 bits (2 bytes), RGB 565 uses half the memory of full RGB 888 (24-bit) and significantly less processing power than 32-bit RGBA. This is ideal for microcontrollers with limited RAM and SPI or parallel displays with 16-bit interfaces. imageconverter 565 v2.3
ImageConverter 565 v2.3 automates the tedious process of:
Instead of writing runtime rotation logic (which consumes CPU cycles), import your source image four times, rotate each by 0°/90°/180°/270°, and store them as separate arrays. This technique is common in GUI sliders and compass displays. The software supports multiple output syntaxes:
Add ImageConverter 565 v2.3: a lightweight, fast image conversion utility that converts images to RGB565 (16-bit) with options for dithering, resizing, alpha handling, and output formats suitable for embedded displays and game engines.
Power users and CI/CD pipelines rejoice. ImageConverter 565 v2.3 can be invoked via command line, allowing automated image conversion as part of your firmware build process. Before understanding the tool, you must understand the
Cause: No dithering, or using ordered dithering on a photographic image. Fix: Re-convert using Floyd-Steinberg dithering. Accept that RGB 565 has limits—consider using RGB 888 if your display buffer can afford it.
