    Generate a JPG image from a raster.

    Generate a JPG image from a raster.

    Use this operation when you have a raster of data that you want to visualize with an image.

    To render a data raster into an image, the operation needs to know which values should be painted with which colors. To that end, you'll need to generate a ColorBreaks object which represents the value ranges and the assigned color. One way to create these color breaks is to use the geotrellis.raster.stats.op.stat.GetClassBreaks operation to generate quantile class breaks.

    Generate a JPG from a raster of RGBA integer values.

    Generate a JPG 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 JPG. If you have a raster with data that you wish to render, you should use RenderJpg 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).
