@developmentseed/deck.gl-raster/gpu-modules

GPU shader modules for raster rendering. Each module is a luma.gl ShaderModule that performs one transformation on raw pixel data — decoding, rescaling, masking, colorization, etc. Compose them into a render pipeline by passing an array of RasterModule entries to the renderPipeline prop on RasterLayer or RasterTileLayer.

import {
  FilterNoDataVal,
  LinearRescale,
} from "@developmentseed/deck.gl-raster/gpu-modules";

const renderPipeline = [
  { module: FilterNoDataVal, props: { value: 0 } },
  { module: LinearRescale, props: { rescaleMin: 0, rescaleMax: 0.05 } },
];

Pipelines run in order: each module receives the output of the previous one. A typical pipeline starts with decoding (e.g. FilterNoDataVal, CompositeBands), applies numeric transforms (LinearRescale), then maps values to colors (Colormap, BlackIsZero, CMYKToRGB).
