ViewBox Mixin#
- class svgwrite.mixins.ViewBox#
The ViewBox mixin provides the ability to specify that a given set of graphics stretch to fit a particular container element.
The value of the viewBox attribute is a list of four numbers min-x, min-y, width and height, separated by whitespace and/or a comma, which specify a rectangle in user space which should be mapped to the bounds of the viewport established by the given element, taking into account attribute preserveAspectRatio.
- ViewBox.viewbox(minx=0, miny=0, width=0, height=0)#
Specify a rectangle in user space (no units allowed) which should be mapped to the bounds of the viewport established by the given element.
- 参数:
minx (number) – left border of the viewBox
miny (number) – top border of the viewBox
width (number) – width of the viewBox
height (number) – height of the viewBox
- ViewBox.stretch()#
Stretch viewBox in x and y direction to fill viewport, does not preserve aspect ratio.
- ViewBox.fit(horiz='center', vert='middle', scale='meet')#
Set the preserveAspectRatio attribute.
- 参数:
horiz (string) – horizontal alignment
'left | center | right'vert (string) – vertical alignment
'top | middle | bottom'scale (string) – scale method
'meet | slice'
Scale methods
Description
'meet'preserve aspect ration and zoom to limits of viewBox
'slice'preserve aspect ration and viewBox touch viewport on all bounds, viewBox will extend beyond the bounds of the viewport
Transform Mixin#
- class svgwrite.mixins.Transform#
The Transform mixin operates on the transform attribute. The value of the transform attribute is a <transform-list>, which is defined as a list of transform definitions, which are applied in the order provided. The individual transform definitions are separated by whitespace and/or a comma. All coordinates are user space coordinates.
- Transform.translate(tx, ty=None)#
Specifies a translation by tx and ty. If ty is not provided, it is assumed to be zero.
- 参数:
tx (number) – user coordinate - no units allowed
ty (number) – user coordinate - no units allowed
- Transform.rotate(angle, center=None)#
Specifies a rotation by angle degrees about a given point. If optional parameter center are not supplied, the rotate is about the origin of the current user coordinate system.
- 参数:
angle (number) – rotate-angle in degrees
center (2-tuple) – rotate-center as user coordinate - no units allowed
- Transform.skewX(angle)#
Specifies a skew transformation along the x-axis.
- 参数:
angle (number) – skew-angle in degrees, no units allowed
- Transform.skewY(angle)#
Specifies a skew transformation along the y-axis.
- 参数:
angle (number) – skew-angle in degrees, no units allowed
- Transform.scale(sx, sy=None)#
Specifies a scale operation by sx and sy. If sy is not provided, it is assumed to be equal to sx.
- 参数:
sx (number) – scalar factor x-axis, no units allowed
sy (number) – scalar factor y-axis, no units allowed
XLink Mixin#
- class svgwrite.mixins.XLink#
XLink mixin
- XLink.set_href(element)#
Create a reference to element.
- 参数:
element – if element is a string its the id name of the referenced element, if element is a BaseElement class the id SVG Attribute is used to create the reference.
- XLink.set_xlink(title=None, show=None, role=None, arcrole=None)#
Set XLink attributes (for href use
set_href()).
Set xlink:actuate and xlink:type by the index operator:
element['xlink:type'] = 'simple'
element['xlink:actuate'] = 'onLoad'
Presentation Mixin#
- class svgwrite.mixins.Presentation#
Helper methods to set presentation attributes.
- Presentation.fill(color=None, rule=None, opacity=None)#
Set SVG Properties fill, fill-rule and fill-opacity.
参见
- Presentation.stroke(color=None, width=None, opacity=None, linecap=None, linejoin=None, miterlimit=None)#
Set SVG Properties stroke, stroke-width, stroke-opacity, stroke-linecap and stroke-miterlimit.
参见
- Presentation.dasharray(dasharray=None, offset=None)#
Set SVG Properties stroke-dashoffset and stroke-dasharray.
Where dasharray specify the lengths of alternating dashes and gaps as <list> of <int> or <float> values or a <string> of comma and/or white space separated <lengths> or <percentages>. (e.g. as <list> dasharray=[1, 0.5] or as <string> dasharray=’1 0.5’)
MediaGroup Mixin#
SVG Tiny 1.2
valid for SVG Elements: animation, audio, desc, image, metadata, title, video
- class svgwrite.mixins.MediaGroup#
Helper methods to set media group attributes.
- MediaGroup.viewport_fill(color=None, opacity=None)#
Set SVG Properties viewport-fill and viewport-fill-opacity.
Markers Mixin#
- class svgwrite.mixins.Markers#
Helper methods to set marker attributes.
- Markers.set_markers(markers)#
Set markers for line elements (line, polygon, polyline, path) to values specified by markers.
if markers is a 3-tuple:
attribute ‘marker-start’ = markers[0]
attribute ‘marker-mid’ = markers[1]
attribute ‘marker-end’ = markers[2]
markers is a string or a Marker class:
attribute ‘marker’ = FuncIRI of markers
Clipping Mixin#
- class svgwrite.mixins.Clipping#
- Clipping.clip_rect(top='auto', right='auto', bottom='auto', left='auto')#
Set SVG Property clip.
