mapscript.rectObj

class mapscript.rectObj(minx: double = - 1.0, miny: double = - 1.0, maxx: double = - 1.0, maxy: double = - 1.0, imageunits: int = 0)

A rectObj represents a rectangle or bounding box. A rectObj may be a lone object or an attribute of another object and has no other associations.

Attributes

maxx	double Maximum easting
maxy	double Maximum northing
minx	double Minimum easting
miny	double Minimum northing
thisown	The membership flag

Methods

__init__(minx: double = - 1.0, miny: double = - 1.0, maxx: double = - 1.0, maxy: double = - 1.0, imageunits: int = 0)

Create new instance. The four easting and northing arguments are optional and default to -1.0. Note the new optional fifth argument which allows creation of rectangles in image (pixel/line) units which are also tested for validity.

draw(map: mapObj, layer: layerObj, image: imageObj, classindex: int, text: char) → int

Draw rectangle into img using style defined by the classindex class of layer. The rectangle is labeled with the string text. Returns MS_SUCCESS or MS_FAILURE

fit(width: int, height: int) → double

Adjust the rect to fit the width and height. Returns cellsize of rect.

getCenter() → mapscript.pointObj

Return the center point of the rectangle.

project(projin: mapscript.projectionObj, projout: mapscript.projectionObj) → int

Reproject rectangle from proj_in to proj_out. Transformation is done in place. Returns MS_SUCCESS or MS_FAILURE

toPolygon() → mapscript.shapeObj

Convert to a polygon of five vertices.

toString() → char

Return a string formatted like: { 'minx': %f , 'miny': %f , 'maxx': %f , 'maxy': %f } with the bounding values substituted appropriately. Python users can get the same effect via the rectObj __str__ method:

>>> r = mapscript.rectObj(0, 0, 1, 1)

>>> str(r)
{ 'minx': 0 , 'miny': 0 , 'maxx': 1 , 'maxy': 1 }
