access: | private
#### Parameters:
double | $pixelPos | pixel coordinate
double | $pixelMax | maximum pixel coordinate
double | $geoMin | minimum geographical coordinate

[ Top ] ### method point2Coords [line 63]
`Point point2Coords( Point $pixelPoint, Dimension $imageSize, Bbox $bbox)`
Converts a point coordinates from pixel to geographical. Pixel coordinates have their origin on image top left. x grows positively from left to right, and y grows from top to bottom. #### Tags:
return: | point in geographical coordinates
static: |
#### Parameters:
Point | $pixelPoint | the point in pixel coordinates
Dimension | $imageSize | the size of the image containing the pixel point
Bbox | $bbox | the geographical bbox extent of the image.
