mapscript.styleObj

class mapscript.styleObj(parent_class: classObj | None = None)

The STYLE object. An instance of styleObj is associated with one instance of classObj.

Overview

The styleObj has the following relationships:

Attributes

angle	double Angle, given in degrees, to draw the line work, default is 0, for symbols of Type HATCH, this is the angle of the hatched lines - see ANGLE

linejoin	int See LINEJOIN - moved from symbolObj in version 6.0
linejoinmaxsize	double See LINEJOINMAXSIZE - moved from symbolObj in version 6.0
maxcolor	colorObj Maximum color in the COLORRANGE
maxscaledenom	double See MAXSCALEDENOM
maxsize	double Maximum pen or symbol width for scaling - see MAXSIZE
maxvalue	double related to color ranges
maxwidth	double Maximum width of the symbol - see MAXWIDTH
mincolor	colorObj Minimum color in the COLORRANGE
minscaledenom	double See MINSCALEDENOM
minsize	double Minimum pen or symbol width for scaling styles - see MINSIZE
minvalue	double related to color ranges
minwidth	double Minimum width of the symbol - see MINWIDTH
offsetx	double Draw with pen or symbol offset from map data, for shadows, hollow symbols, etc - see OFFSET
offsety	double Draw with pen or symbol offset from map data, for shadows, hollow symbols, etc - see OFFSET
opacity	int See OPACITY
outlinecolor	colorObj Outline pen color - see OUTLINECOLOR
outlinewidth	double See OUTLINEWIDTH
pattern	pattern : list Python Only
patternlength	int immutable Number of elements in the pattern attribute
polaroffsetangle	double Specified the angle - see POLAROFFSET
polaroffsetpixel	double Specifies the radius/distance - see POLAROFFSET
rangeitem	char Attribute/field that stores the values for the Color Range Mapping - see RANGEITEM
rangeitemindex	int The index of the range item - see RANGEITEM
refcount	int immutable number of references to this object
size	double Pixel width of the style's pen or symbol - see SIZE
sizeunits	int Supersedes class's SIZEUNITS to allow fine-grained sizing for improved SLD (RFC 124)
symbol	int The index within the map symbolset of the style's symbol - see SYMBOL
symbolname	char immutable Name of the style's symbol - see symbolname
thisown	The membership flag
width	double Width refers to the thickness of line work drawn, in pixels - default is 1, for symbols of type HATCH, the with is how thick the hatched lines are - see WIDTH

Methods

__init__(parent_class: classObj | None = None)

Returns new default styleObj instance. The parent_class is optional.

clone() → styleObj

Return an independent copy of the style with no parent class.

注釈

In the Java & PHP modules this method is named cloneStyle.

convertToString() → char

Saves the object to a string. Provides the inverse option for styleObj.updateFromString()

getBinding(binding: int) → char const

Get the attribute binding for a specified style property. Returns NULL if there is no binding for this property.

getGeomTransform() → char

Get the GEOMTRANSFORM for the style.

pattern_get() → void

Python Only** Get the pattern for the style.

pattern_set(nListSize: int) → void

Python Only** Set the pattern for the style.

removeBinding(binding: int) → int

Remove the attribute binding for a specified style property.

setBinding(binding: int, item: char const) → int

Remove the attribute binding for a specified style property.

setGeomTransform(transform: char) → void

Set the GEOMTRANSFORM for the style.

setSymbolByName(map: mapObj, symbolname: char) → int

Setting the symbol of the styleObj given the reference of the map object and the symbol name.

updateFromString(snippet: char) → int

Update a style from a string snippet. Returns MS_SUCCESS or MS_FAILURE
