Appearance
Interface: ShapeLineProps ​
Line (stroke) options.
A stroke is painted much like a fill: in addition to a solid color, it accepts the inherited gradient and pattern fill options. Setting gradient (or type: 'gradient') paints a gradient stroke, e.g. line: { width: 1, gradient: { kind: 'linear', angle: 0, stops: [{ position: 0, color: 'accent3' }, { position: 100, color: 'accent4' }] } }.
A picture stroke is not one of them, which is why image and type: 'image' are subtracted from the inherited fill props rather than carried. <a:ln>'s paint child is EG_LineFillProperties — a:noFill, a:solidFill, a:gradFill, a:pattFill and nothing else — so unlike a shape interior a stroke has no a:blipFill slot to put a bitmap in, and a package that emitted one is what PowerPoint answers with a repair prompt. The interface carried image from ShapeFillProps regardless, and no call site ever registered the media for it, so a picture stroke reached the emitter with no rel and painted nothing. It is now spelled out as unsupported: a JS caller who sets it anyway gets line/image-fill-unsupported.
A stroke also does not take the bare-colour shorthand a fill does — see FillOption for why. Spell it line: { color: 'FF0000' }.

End arrow type — the ST_LineEndType set (a:tailEnd/@type).
gradient? ​
optionalgradient?:GradientFillProps
Native PPTX gradient fill options. Setting this (or type: 'gradient') paints the shape interior with a gradient instead of a color.
Inherited from ​
pattern? ​
optionalpattern?:PatternFillProps
Native PPTX pattern fill options. Setting this (or type: 'pattern') paints the shape interior with a two-color preset pattern instead of a color.
