Fix Default Gradient Stop Color

Fixes the default color for gradient stop-color is not defined within a gradient.

RadialGradient Stroke

Adds ability to stroke a path with a radial gradient.

Enhances error logging to ensure it is logged to stderr and includes details of erroneous SVG line / file where appropriate.

Image.Options

Adds Image.Options to provide a way for the client to control how the SVG is rendered.

A single option is provided .hideUnsupportedFilters which hides any SVG element that includes an unsupported filter. This option is not enabled by default. Images with unsupported filters render without the filter but log to stderr with a platform specific hint pointing to the option;

Warning: <feGaussianBlur> is not supported. Elements with this filter can be hidden with UIImage(svgNamed: "yawn.svg", options: .hideUnsupportedFilters)

Warning: <feGaussianBlur> is not supported. Elements with this filter can be hidden with NSImage(svgNamed: "yawn.svg", options: .hideUnsupportedFilters)

Warning: <feGaussianBlur> is not supported. Elements with this filter can be hidden with [--hideUnsupportedFilters]

LinearGradient Stroke

Adds ability to stroke a path with a linear gradient.

RadialGradiant Improvements

Supports radial gradient focal points

RadialGradient

Initial support for radial gradients

Closed Path Location Fix

Last location of a closed path now correctly moves back to the start of the last unbroken segment.

currentColor

Adds support for the indirect currentColor keyword.

initWithSVGData

Adds convenience initialisers to platform images;

UIImage(svgData: Data)
UIImage(contentsOfSVGFile path: String)

NSImage(svgData: Data)
NSImage(contentsOfSVGFile path: String)

And exports to Objective-C

- (instancetype) initWithSVGData: (NSData *)
- (instancetype) initWithContentsOfSVGFile: (NSString *)
