# Image to OpenSCAD array, v12

# Convert image to OpenSCAD array

This utility accepts an image that can be displayed in your browser, and converts it to grayscale expanded to use the maximum possible luminance range. The file types supported depend on your browser. Alpha channel is ignored. After processing the image as desired, you may save it as an OpenSCAD array.

Keep the output image width small! A large size results in a huge output file when converting an image to text data.

You can also paste an image (Ctrl+V) into this section from your clipboard.
