### Question:
TileSetCoordinateSpace { public Point<C2D> toPoint(Pixel pixel) { return this.mupTransform.toPoint(pixel); } TileSetCoordinateSpace(Point<C2D> origin, Dimension tileDimension, Envelope<C2D> extent, double unitsPerPixel); Envelope<C2D> boundingBox(TileCoordinate coordinate); PixelRange tilePixelRange(TileCoordinate coordinate); Dimension tileSetPixelDimension(); double tileWidthInMapUnits(); double tileHeightInMapUnits(); TileCoordinate tileCoordinateContaining(Point<C2D> point, boolean lowerLeftInclusive); double unitsPerPixel(); PixelRange pixelRange(Envelope<C2D> bbox); Pixel toPixel(Point<C2D> point); Point<C2D> toPoint(Pixel pixel);  }### Answer:
@Test public void test_to_point() { Point received = space1.toPoint(Pixel.valueOf(0, 199)); Point expected = point(crs, c(50, 55)); assertEquals(expected, received); received = space1.toPoint(Pixel.valueOf(199, 0)); expected = point(crs, c(1045, 1050)); assertEquals(expected, received); received = space1.toPoint(Pixel.valueOf(199, 199)); expected = point(crs, c(1045, 55)); assertEquals(expected, received); received = space1.toPoint(Pixel.valueOf(0, 0)); expected = point(crs, c(50, 1050)); assertEquals(expected, received); received = space1.toPoint(Pixel.valueOf(10, 160)); expected = point(crs, c(100, 250)); assertEquals(expected, received); received = space1.toPoint(Pixel.valueOf(201, 201)); expected = point(crs, c(1055, 45)); assertEquals(expected, received); }
