Change list

  • New COG render pipeline inference in render-pipeline.ts
    • Currently will infer rendering for 3-band RGB and 1-band paletted images
    • still need to implement photometric support for black is zero and white is zero
  • New shader modules:
    • Convert CIELAB, CMYK, YCbCr color spaces to RGB
  • Helper function to parse the GDAL_NODATA tiff tag
  • Simplify Land Cover and cog-basic example applications by using default render pipeline.
  • Update top-level README
  • Set up render pipeline tests. Polyfill the ImageData class
    • Add test that land cover image defaults to correct render pipeline
