Concrete Value Members

  1. def renderPng(colorRamp: ColorRamp): Png
  2. def renderPng(colorMap: ColorMap): Png
  3. def renderPng(colorEncoding: PngColorEncoding): Png

    Generate a PNG from a raster of color encoded values.

    Generate a PNG from a raster of color encoded values.

    Use this operation when you have created a raster whose values are already encoded color values that you wish to render into a PNG.

  4. def renderPng(): Png

    Generate a PNG from a raster of RGBA integer values.

    Generate a PNG from a raster of RGBA integer values.

    Use this operation when you have created a raster whose values are already RGBA color values that you wish to render into a PNG. If you have a raster with data that you wish to render, you should use RenderPng instead.

    An RGBA value is a 32 bit integer with 8 bits used for each component: the first 8 bits are the red value (between 0 and 255), then green, blue, and alpha (with 0 being transparent and 255 being opaque).
