23067 2009-01-01 13:51:59 -0800 [CG] Canvas: stroked text with pattern or gradient can have truncated miters 2025-12-26 11:16:11 -0800 1 1 1 Unclassified WebKit Canvas 528+ (Nightly build) Mac OS X 10.5 NEW InRadar P2 Normal --- 1 simon.fraser webkit-unassigned dino krit mdelaney7 oliver simon.fraser webkit-bug-importer oldest_to_newest 103988 0 simon.fraser 2009-01-01 13:51:59 -0800 CanvasRenderingContext2D::drawTextInternal() uses the computed textRect as the size of the mask image created for painting text stroke with a gradient or pattern. textRect is too small if stroking text, because it does not take the bounds of the stroke into account; it fails to account for miters etc. 103990 1 26351 simon.fraser 2009-01-01 13:58:02 -0800 Created attachment 26351 Testcase 108479 2 krit 2009-02-05 12:39:51 -0800 Maybe Path::strokeBoundingRect() can help here. We moved it from SVG to Path. See SVGPaintServer.cpp and RenderObject.cpp for the usage. 111407 3 krit 2009-02-27 00:25:47 -0800 Other platforms don't use clipToImageBuffer anymore. That means it's only a CG related bug. My last suggestion can't work here. Text's are no paths :-P But why using clipToImageBuffer for both, gradients and pattern. We just need it for gradients, right? 1702854 4 webkit-bug-importer 2020-10-29 14:02:43 -0700 <rdar://problem/70824500> 26351 2009-01-01 13:58:02 -0800 2009-01-01 13:58:02 -0800 Testcase canvas-stroked-text.html text/html 1313 simon.fraser PCFET0NUWVBFIGh0bWwgUFVCTElDICItLy9XM0MvL0RURCBIVE1MIDQuMDEgVHJhbnNpdGlvbmFs Ly9FTiIKICAgImh0dHA6Ly93d3cudzMub3JnL1RSL2h0bWw0L2xvb3NlLmR0ZCI+Cgo8aHRtbCBs YW5nPSJlbiI+CjxoZWFkPgogIDxtZXRhIGh0dHAtZXF1aXY9IkNvbnRlbnQtVHlwZSIgY29udGVu dD0idGV4dC9odG1sOyBjaGFyc2V0PXV0Zi04Ij4KICA8dGl0bGU+Q2FudmFzIEluY3JlbWVudGFs IFJlcGFpbnQ8L3RpdGxlPgogIDxzdHlsZSB0eXBlPSJ0ZXh0L2NzcyIgbWVkaWE9InNjcmVlbiI+ CiAgICBjYW52YXMgewogICAgICB3aWR0aDogNDAwcHg7CiAgICAgIGhlaWdodDogMjAwcHg7CiAg ICAgIGJvcmRlcjogMnB4IHNvbGlkIGJsYWNrOwogICAgfQogIDwvc3R5bGU+CiAgPHNjcmlwdCB0 eXBlPSJ0ZXh0L2phdmFzY3JpcHQiIGNoYXJzZXQ9InV0Zi04Ij4KCiAgICBmdW5jdGlvbiBpbml0 aWFsaXplQ2FudmFzKCkKICAgIHsKICAgICAgdmFyIGNhbnZhcyA9IGRvY3VtZW50LmdldEVsZW1l bnRCeUlkKCdjYW52YXMnKTsKICAgICAgY2FudmFzLmhlaWdodCA9IDIwMDsKICAgICAgY2FudmFz LndpZHRoID0gNDAwOwogICAgICB2YXIgY3R4ID0gY2FudmFzLmdldENvbnRleHQoJzJkJyk7Cgog ICAgICBjdHguZm9udCA9ICI4MHB4ICdUaW1lcyBOZXcgUm9tYW4nIjsKICAgICAgY3R4LmxpbmVX aWR0aCA9IDQwOwogICAgICBjdHguZmlsbFN0eWxlID0gJ2JsYWNrJzsgCgogICAgICB2YXIgZ3Jh ZGllbnQgPSBjdHguY3JlYXRlTGluZWFyR3JhZGllbnQoMCwgMCwgMCwgMTUwKTsKICAgICAgZ3Jh ZGllbnQuYWRkQ29sb3JTdG9wKDAsICd5ZWxsb3cnKTsKICAgICAgZ3JhZGllbnQuYWRkQ29sb3JT dG9wKDEsICdyZWQnKTsKCiAgICAgIGN0eC5zdHJva2VTdHlsZSA9ICdncmF5JzsKICAgICAgY3R4 LnN0cm9rZVRleHQoIlZXIiwgMzAsIDEwMCk7CiAgICAgIGN0eC5maWxsVGV4dCgiVlciLCAzMCwg MTAwKTsKCiAgICAgIGN0eC5zdHJva2VTdHlsZSA9IGdyYWRpZW50OwogICAgICBjdHguc3Ryb2tl VGV4dCgiVlciLCAyMjAsIDEwMCk7CiAgICAgIGN0eC5maWxsVGV4dCgiVlciLCAyMjAsIDEwMCk7 CiAgICB9CiAgICAKICAgIGZ1bmN0aW9uIHBhZ2VMb2FkZWQoKQogICAgewogICAgICBpbml0aWFs aXplQ2FudmFzKCk7CiAgICB9CiAgPC9zY3JpcHQ+CjwvaGVhZD4KPGJvZHkgb25sb2FkPSJwYWdl TG9hZGVkKCkiPgoKPHA+TWl0ZXJzIG9uIGdyYWRpZW50IHN0cm9rZSBzaG91bGQgbm90IGJlIHRy dW5jYXRlZDwvcD4KPGNhbnZhcyBpZD0iY2FudmFzIj48L2NhbnZhcz4KCjwvYm9keT4KPC9odG1s Pgo=
