Description Rolf Eike Beer 2010-09-15 21:22:51 UTC

Version:           4.5.1 (using KDE 4.5.1) 
OS:                Linux

Microsoft provides testcases for various browser compliance things (see http://samples.msdn.microsoft.com/ietestcenter/#html5). Some of the HTML5 canvas tests faile:

#1 toDataURL on zero width canvas
#5 createlinearGradient() with two points same
#11 bezierCurveTo() must ensure subpaths
#15 Ignore property-independent style sheet syntax "inherit" in Text
#16 "font-size" component
#17 Text maxWidth
#18 drawImage() with SVG images

Reproducible: Didn't try

Comment 3 Rolf Eike Beer 2013-04-17 12:27:13 UTC

The number of the test inside the list on the MS page have changed, but the tests are still there and fail.

Dear user,

KHTML (and KJS) was a long time more or less unmaintained and got removed in KF6.

Please migrate to use a QWebEngine based HTML component.

We will do no further fixes or improvements to the KF5 branches of these components beside important security fixes.

For security issues, please see:

https://kde.org/info/security/

Sorry that we did not fix this issue during the life-time of KHTML.

Greetings
Christoph Cullmann
