From: Dr J R Stockton on 28 Dec 2009 17:17 Page <http://www.merlyn.demon.co.uk/js-grphx.htm>, both locally and from server, in XP sp3, draws to a canvas when button ReadText is pressed. The canvas is then copied to a PNG. In my up-to-date Chrome 3.0.195.38, right-click gives the expected sort of menu, but "Save image as" is disabled. The corresponding entry is not disabled in Opera, Safari, Firefox. Is that a bug or a feature? Comment? The image can less elegantly be copied to the clipboard and pasted into Windows Paint and saved. A PNG inserted into a page in the ordinary way can be saved directly from right-click in my Chrome. -- (c) John Stockton, nr London, UK. ?@merlyn.demon.co.uk Turnpike v6.05.

That seems distinct, since the graphic has been taken from the canvas and loaded into an image. <FAQENTRY> Perhaps the FAQ should have an entry on Bug Reporting, giving URLs for major implementations and indicating what details should (where not automated) be supplied. -- (c) John Stockton, near London, UK.
