PixelBurst is a image generation tool that processes text-based (.bt files) templates into PNG images. The templates define pixel colors and transparency using a simple syntax, allowing you to create pixel art or patterns programmatically.
[color]: Specifies a color for a single pixel. E.g., [red] creates a red pixel.[color/opacity]: Specifies a color with a specific opacity (0-100%). E.g., [red/50] creates a red pixel with 50% opacity.[color:columns]: Expands the specified color across a number of columns. E.g., [red:3] creates three adjacent red pixels.[color/opacity:columns]: Expands the specified color and opacity across multiple columns. E.g., [red/50:3] creates three adjacent red pixels with 50% opacity.[](rows): Repeats the entire preceding row a specified number of times. E.g., (...) repeats the row downwards.
Below are some examples of how to define your templates:
A basic 3x2 grid with different colors:
[red][green][blue]
[white][black][transparent]
Repeat the entire row 3 times vertically:
[red][green][blue](3)
Expand each color horizontally across 3 columns:
[red:3]
[green:3]
[blue:3]
Specify colors with varying levels of opacity:
[red/20]
[green/40]
[blue/60]
Expand colors horizontally across 3 columns, applying opacity to each expanded column:
[red/20:3]
[green/40:3]
[blue/60:3]
Place your templates in the src directory with a .bt extension. Run the script, and the output will be generated in the dist directory as PNG files. Ensure your color definitions are included in the palette.json file.
