Parameters:

bounds - limits of the covered area

data - point to use to interpolate

var -

destination - image to draw in

width - of the target image

height - of the target image

alpha - transparency

colorMap - the colorMap (greyScale etc)

minValue - the minimum value in the dataset (affects colors)

maxValue - the maximum value in the dataset (affects colors)
