http://www.w3.org/Bugs/Public/show_bug.cgi?id=11417 Summary: define pixel interpolation when scaling Product: SVG Version: SVG 1.2 Tiny Platform: All OS/Version: All Status: NEW Severity: normal Priority: P2 Component: Rendering Model AssignedTo: schepers@w3.org ReportedBy: j.chetwynd@btinternet.com QAContact: www-svg@w3.org when pixels are defined, and the display is rendered at an alternative scale, it is vital that interpolation is accurate. in the attached example, which is simple to understand but not a reduced testcase, a gradient matrix is interpolated using lerp, pixel by pixel, across a defined width and height. in this instance for simlicity, the root is deliberately set as a percentage, however zooming would also have a similar effect. currently all though there is variation, Opera, Mozilla and Webkit nightlies all display significant artefacts. interpolation does take processing, and it may be that authors will need to consider this, none the less the browser should not introduce artefacts. -- Configure bugmail: http://www.w3.org/Bugs/Public/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug.
